Description: Practical Organic Synthesis
Success in an experimental science such as chemistry depends on good laboratory practice, a knowledge of basic techniques, and the intelligent and careful handling of chemicals. Practical Organic Synthesis is a concise, useful guide to good laboratory practice in the organic chemistry lab with hints and tips on successful organic synthesis. Topics covered include:
safety in the laboratory
environmentally responsible handling of chemicals and solvents
crystallisation
distillation
chromatographic methods
extraction and work-up
structure determination by spectroscopic methods
searching the chemical literature
laboratory notebooks
writing a report
hints on the synthesis of organic compounds
disposal and destruction of dangerous materials
drying and purifying solvents
Practical Organic Synthesis is based on a successful course in basic organic chemistry laboratory practice which has run for several years at the ETH Zurich and the University of Bern, and its course book Grundoperationen, is now in its sixth edition. Condensing over 30 years of the authors’ organic laboratory teaching experience into one easy-to-read volume, Practical Organic Synthesis is an essential guide for those new to the organic chemistry laboratory, and a handy benchtop guide for practising organic chemists.

Laboratory Rules for the HCI Emergency alarm: Tel. 888
1. The most important regulations for the work place: Must!
Every employee must act responsibly with respect to safety and to the environment. All newly arriving employees will be instructed by their group safety officer about safety and environmental issues, and must follow his/her orders. New employees must oblige themselves to follow all safety- and environmental protection rules and regulations and act according to orders from the Stab SGU.
Protect yourself!
Personal protection equipment is obligatory when working with chemicals and equipment; 1st priority: safety glasses! People who wear glasses must use safety goggles over their glasses (these can be obtained from the HCI-shop). For ETH employees, safety glasses with lenses are available upon request from the Stab SGU. It is obligatory to wear a protective laboratory coat as well as laboratory compatible, flame resistant normal clothes. Where necessary, protective gloves, breathing apparatus, etc. must be used.
Workspace!
Generally, users must keep the workspaces and fume hoods clean and in order, and are responsible for good housekeeping and adequate working hygiene. Workspaces and fume hoods may not be filled with large amounts of chemicals. The service team can close the dirty workspace off. Desk-areas in laboratories may not be used to place, store or handle chemicals or objects contaminated with chemicals.
Forbidden!
Food and consumption products in any form, cosmetics and medications, may never be stored and used near chemicals, biological agents, dangerous equipment, etc. Smoking is prohibited everywhere within HCI.
Contamination!
Used protective gloves must be disposed of at the place of use. Never walk through the building with contaminated gloves or other tools. People wearing gloves will not be helped at the various service desks.
Risk analysis!
When working with chemicals or biological agents that bear increased safety risks, the local safety officer or assistant must be informed in advance. For such work, the students, apprentices, guests, service technicians etc. require the direct presence of a knowledgeable laboratory assistant. Before high-risk work starts, a danger/risk analysis must be completed. Pay attention to Material Safety Data Sheets as well as pictograms on the chemicals labels and GHS H-/P-statements (risk/safety-statements, replacing the older R-/S-statements). Tips: www.msds.com (requires registration), www.reaxys.com. If no MSDS data are available, it must be made sure that all possible risk factors have been considered that may be related to the unknown chemical. Be aware of the general rule: the smaller the amounts of educts and products used in the experiment, the smaller the possible risks and effects of accidents. For dangerous experiments, the Poison Laboratory HCI D312 is available after contacting the safety officer or laboratory assistant.
Ignition!
Open fire or ignition sources (e.g. hot air guns, bunsen burners with gas bottles or hose) may only be used in rooms where no flammable compounds reside in near vicinity. Alkali metals and their hydrides can ignite spontaneously in the vicinity of air and water. Special care must be taken with distillation residues, which may contain alkali metals.
Fumes!
Any work using or producing toxic, flammable and malodorous chemicals, gases, aerosols or fumes, must be done in appropriate fume hoods. Additional absorbers must be installed to catch possibly escaping gases, fumes and aerosols.
Overpressure!
Vacuum, overpressure and stirring operations in unsuitable glass equipment may lead to fracturing of the glass. Quality and wall thicknesses of the used glass containers and equipment must be selected according to the intended use. Experimental autoclaves must be equipped with a pressure gauge and with a overpressure protection disc, and before use, require approval from the Stab SGU when the pressurized volume exceeds >10 [bar x l], or may be operated in the high pressure laboratory, depending on space requirements.
Prevention!
Before starting any experiment, all required protection measures must be taken in advance (and necessary emergency material must be organized) in order to prevent any possible accident. This also includes protection for spreading bad smelling compounds!
Gas cylinders!
Gas cylinders must always be secured against falling by chaining. Gas cylinders and pressurized exit gas require appropriate pressure reducing valves. Corroded pressure reducers may never be used.
Liquefied gases!
Additionally to the risk of suffocation and cold burns, using liquefied gases requires: Special awareness for Oxygen-enrichment in liquid Nitrogen, especially in cold traps of high vacuum systems. During air supplying, the Oxygen-enrichment with highly flammable liquid Oxygen occurs in the cold traps, which are cooled with liquid Nitrogen. The Oxygen can react very strongly with condensed solvents when they thaw. Ampoules (or similar containers) with chemicals that have been frozen out with liquid Nitrogen under Argon protection may never be sealed in these conditions. Warming up will possibly lead to evaporation of frozen Argon, and may cause a serious risk of explosion due to overpressure.
Doors and escape
routes!
Laboratory-, emergency balcony-, escape- and entrance doors to the building may never be blocked with any objects, left open, or prevented from closing with a wedge. Closed doors guarantee the building ventilation balance, as well as sufficient underpressure in the laboratories, so that incidents can be better held back and fought. In case of emergency, work must be interrupted and one must leave the laboratory, until the cause of the incident has been removed! Furthermore, open balcony doors in the D- and E-floors allow unauthorised people as well as creatures such as mice, insects, etc. enter the building. The laboratory service team will remove and dispose of illegally deposited objects on the escape route or escape balconies.
Respect!
Sound-/radio equipment may only be used with permission of the superiors and may never be heard outside the personal area. In case of unacceptable noise or disco states, the laboratory service will disconnect and remove the equipment.

Laboratory Rules for the HCI Emergency alarm: Tel. 888 2. Building and Laboratory operation regulations for HCI:
Instructions: Balcony- and Laboratory doors may never be left open! Stepping on the escape balconies in front of the practical work laboratories is (except in emergencies) forbidden.
It is allowed to stay on the escape balconies (except in front of the practical work laboratories) as long as the doors are closed
behind you.
The automatic door closing devices may never be removed from the doors between the laboratories and the corridor.
The viewing windows in the laboratory doors may never be covered or taped off, except when permission from the Stab SGU
has been obtained (e.g. in laser laboratories).
Transport of chemicals (including for waste disposal purposes): special safety carrying baskets must be used for the
transportation of chemicals inside the building, special Dewars for the transport of liquefied gases. Gas cylinders may only be
transported with a screwed on cap and chained to special trolleys. Chemicals, liquefied gases, mobile waste disposal units and
pressurized gas cylinders may only be transported using the goods lift, never with a persons' lift.
3. Technical infrastructure and equipment: 3.1 In general:
Only certified and tested laboratory equipment may be used for experiments and only for their intended use. Use of hobby
and household equipment for laboratory experiments is not allowed. Never use damaged glass parts (risk of injury); dispose of
damaged glass parts (glass waste) or send it to the glass-blower shop for repair.
Operation manuals must be kept with the equipment. Before using equipment one must always read the instruction manuals,
or get help and advice from an experienced person!
Before taking new equipment and apparatus into operation: test them for leaks (water, vacuum, gas connections, etc.). Avoid
closed systems because heating, reactions, etc. may cause the risk of overpressure! Check all cabling, hose connections, and
seals of any kind regularly for disintegration, fatigue or damage, and replace defective parts if needed.
3.2 Standard laboratory fume hoods:
To protect oneself and to protect the environment, the window of the fume hood should always be kept as low as possible. Note:
with a fully opened window, not all gases that have a higher density than air can be transported away anymore.
Operation of the fume hoods:
o Function "Tag" (day) respectively "Std" (hours): When actuated, the timer for the operation of the fume hood is
activated, and the indicator "Betrieb" (operation) lights up. After the specified time has expired, the exhaust ventilation will
automatically reduce to the minimum prescribed value, and the indicator "Abluft aus" (no exhaust) lights up.
o Function "Not" (emergency): When pressing, this switches the fume hood exhaust ventilation to maximum power,
generally for 15 minutes.
o Indicator "Zu niedrig" (too low) combined with an acoustic warning: there is not enough exhaust ventilation power
available. If this situation cannot be solved, any dangerous experiments have to be stopped immediately. Problems must be
reported to the safety officer or assistant.
o Indicator "Schieber zu": Window position it too high!
o Functions "Quit": Turning off the acoustic alarm.
3.3 Local laboratory vacuum networks:
The membrane vacuum pumps for vacuum networks need to be checked several times a day for a filled condensate tank.
Defects must be reported to the group safety office. Membrane vacuum pumps (type Vacuubrand or Büchi) can be given for
service or repair to the central repair service in the HCI-shop.
Only rotation evaporation equipment may be permanently connected to the vacuum network. It is allowed to quickly 'borrow'
such a vacuum network for other purposes, as long as those who require a good vacuum are informed and agree. For all other
purposes it must be checked beforehand if nearby vacuum networks would suffer from a long-term vacuum loss of quality.
It is absolutely forbidden to suck up liquids (even in small amounts) with a vacuum network! A liquid trap must always be
connected between the vacuum using system and the vacuum module.
Accidentally pumped liquids into the vacuum network must always be reported immediately to the safety officer or the assistant.
During operation of the membrane vacuum pump systems, the pump exhaust must always be fed to an extraction device, never
in the room atmosphere.
3.4 Cooling water modules in the media columns:
Operation: The cooling water circuit is closed when the valve is turned to the 0-position and the flow control valve is closed.
To open the cooling water flow: turn the valve to the 1-position, and then carefully open the flow control valve. Prevent
pressure shocks! Cooling water connector Screw on nipple drip stop
- 11 -
Laboratory Rules for the HCI Emergency alarm: Tel. 888
Drip-stops are mounted inside the supply and return connectors of the module, which prevent the leaking of water from the
connections in case no connectors are mounted. Screwing the connectors onto the cooling water module press the drip-stops
inwards and opens the cooling water circuit, as long as the valves are open. Due to corrosion and deposits it happens frequently
that the drip-stops get jammed in the open position and therefore the connections leak water if they are released. This means that
when opening the valves without connections, water can suddenly flow!
In case the drip-stops are leaking or dripping water: build a bridging connection from the supply to the return connector,
or mount a closed cooling water loop.
In case water is still leaking from the cooling water module after bridging the connections, this should be reported immediately
to the safety officer or the assistant.
In an emergency water leak use telephone 888 to inform the alarm office and then close the main cooling water valve in the
services duct in the corridor (marked with red dots). The door to this service duct can be unlocked with your house key. Make
sure other cooling water dependent equipment and experiments are secured before shutting down the cooling water supply!
When cooling water modules are no longer needed and nothing else was agreed upon, the media connections must be
removed immediately. In case of a leaking connection, leave the bridging connection.
3.5 Gas modules in media columns:
Operation: always open gas valves slowly (prevent pressure shocks! Prevent unwanted pressure increases in closed
containers. Blocked or broken gas valves, as well as uncontrollable pressure should be reported to the safety officer or
assistant.
Note: the gas module can only regulate the gas pressure not the gas flow. A flow regulator is available from the HCI-shop.
Prevent unnecessary wasting of Nitrogen gas, always make sure to use a safe but carefully chosen amount of Nitrogen
purging gas.
3.6 Media connections:
Media connections: all nipple/hose type media connections must be secured with straps on the side of the media column as
well as on the equipment side. Only proper hose qualities may be used for cooling water and gas connections. Methane
connections also have a special type of hose. When you smell natural gas, immediately dial 888 and inform the alarm office.
3.7 Freezer/fridges; rotary vane vacuum pumps:
Freezer/fridges must be regularly checked; cleaned and de-iced (the melting water must be caught properly).
Rotary vane vacuum pumps: in case solvents or similar chemicals are being distilled with rotary vane vacuum pumps, cooling
traps must always be used to prevent condensation of solvents inside the pump oil. Before returning a pump to the HCI shop for
repair, the user must complete a contamination declaration and the oil must be drained from the pump and must be properly
disposed of.
4. Waste disposal:
Waste disposal facilities HCI D276:
o Opening hours: Monday - Friday between 14 and 16 hrs (Tel: 34603) o During semester holidays only Tuesdays and Thursdays between 14 and 16 hrs or by appointment.
(Tel: 34983/37689)
Chlorinated and non-chlorinated solvents wastes are collected separately in mobile waste disposal units. When these are full, they
must be brought to the waste disposal office D276, immediately. There the proper facilities exist to empty them. The mobile waste
disposal units must be cleaned regularly (basin, outside, structure). Defective and leaking mobile waste disposal units must be
reported immediately to the safety officer or assistant!
Liquid special wastes may be disposed of in well labelled 5, 10 or 20 L – liquids containers, chemicals in 5, 10 or 20 L – plastic
buckets. Organic and inorganic solids, Mercury, acids, bases, heavy metal containing solutions, photo chemicals, pharmaceuticals
etc. must always be collected and disposed of separately. Filled containers must be taken to the waste disposal facilities properly
closed and secured in their own catchments. Such empty containers and catchments can be obtained there for free.
Tissues, objects etc which are contaminated with less toxic chemicals may be placed in garbage bins only if it is packaged in
such a way that the cleaning staff will not suffer any health or injury risks when emptying the bins. Chemicals themselves may
never be placed in garbage bins!
All biological wastes must be collected in autoclavable, labelled containers and must be autoclaved afterwards, before they are
placed in normal garbage bins.
- 12 -
Laboratory Rules for the HCI Emergency alarm: Tel. 888
Glass waste, needles, sharp objects: These should never be disposed of via the normal garbage. There is a risk of injury and
contamination by the cleaning staff. Syringe needles must be disposed of in special waste containers (available in the HCI-shop)
and handed over to the central disposal location HCI D276.
Glass bottles: This is not collected separately by colour. In most laboratories a separate collection bin for glass is available. Always remember to rinse bad smelling or fuming glass vessels (previously emptied) with water or solvents prior to disposal (observe safety information on label)! For very toxic substances, the rinsing water is also collected and disposed of as being hazardous. The disposal of waste glass with hazardous chemical residues is forbidden. Glassware that cannot be cleaned of hazardous waste must be brought to the waste disposal office.
Paper, cardboard, Aluminium, PET bottles must be disposed of in the dedicated recycling collection bins distributed throughout HCI!
5. Storage of toxic, bad smelling and corrosive chemicals:
Highly toxic, bad-smelling and corrosive chemicals must be stored separately in appropriate, vented safety cabinets, freezers or refrigerators. These containers must be specially marked, e.g. with references to the dangers involved in using these chemicals, as well as the required actions in the event of an incident. Larger quantities of liquids containers must be stored in chemically resistant drip pans. Note: When filling of solvents in glass bottles, these may never be completely filled and closed for storage; at least 5% empty volume must be left, to prevent breaking of the glass as the room temperature increases.
6. Labelling of chemicals and samples: registration in the chemicals database:
For permanent and temporary storage of chemicals and samples, used chemicals containers, and neutral glass bottles (not recognizable as food containers) may be used. Existing labels must be covered completely with a proper product label. The new identification label for solvents must additionally be covered with a transparent plastic protective tape. Chemicals in spray bottles, flasks, Erlenmeyer glasses etc. must at least be labelled with a special marker that is hard to dissolve. Solvent drums must be labelled with engraved tags. Identification of contents for chemicals and samples:
o Product name and/or formula
o User's name
o Date of filling
o For hazardous materials: Risk notes, storage conditions
o For solvent drums: engraved tag with product name and laboratory number
Use of empty food-, cosmetics- and medication containers for the storage of all chemicals and samples is forbidden!
Chemicals can be ordered only with the consent of the group leader or assistant. Newly delivered chemicals as well as collection and the return of chemicals from and to the storage room must be recorded in the central chemical inventory systems without exception. Never return empty, damaged, unlabeled containers or contaminated chemicals back to the chemical storage.
7. Night-, weekend-, and holiday work:
Interns, students, and apprentices may never work in the laboratory without the supervision of an assistant. Any work before 08.00 or after 19.00 hrs requires an additional approval from the head of the working group. Diploma students may work before 08.00 resp. After 19.00 hrs, their mentor is responsible for their safety.
All other people must make sure to have a second emergency qualified person to be present, whenever they work with chemicals or glass equipment on holidays or between 22.00 and 06.00 hrs. Both people are responsible for each other and for a safe work procedure. Planned night-, weekend- and holiday-work using chemicals or glass equipment must be announced early to the group safety officer or assistant.
8. At the end of the workday:
Reactions and equipment without increased safety risk, which need to stay in operation over night (if possible with safety drip pan; heated only with a contact thermometer or regulators), must have a night work sign (available in the HCI-shop). This night work sign must be easily visible at the fume hood window, or must be fastened in the vicinity of the experiment or the equipment. Equipment for continuous operation must be labelled with a phone number of the responsible person and with information on what to do in an emergency.
Everyone has to make a final inspection in the laboratory after work, and ensure that all equipment without a night work sign is turned off, all chemicals are stored away safely, all valves of gas and liquids on the media columns and on gas cylinders are closed, and that all equipment running overnight is declared with a night work sign, and reaction vessels are working properly. Especially the distilleries with alkali metals in the distillation residue, as well as the main natural gas switch must be checked to be off.
Never touch the main electrical switch for the laboratory (except in case of an emergency)!
9. Disregard of the laboratory and operation rules:
The safety officers, assistants, and group leaders must enforce the observance of the Labour policy and operational requirements.
The safety officer, assistant or group leader must report multiple violations of the laboratory rules by a person or group of people to the Stab SGU. The head of the Stab SGU decides on further action.
Every incident must be reported. Accidents, near accidents, critical situations, etc. must be reported to the Stab SGU.
10. Responsibilities, web sites and contact addresses:
The Stab SGU implements the ETH safety policy at HCI.
Further general and work group specific laboratory rules are to be obeyed, too.
Also consult the safety manual of the Stab SGU.

Information and overview for the Equipment box
In your equipment box (stacking container, white, 50 cm x 44 cm x 10 cm) you will find, amongst other things, a modern new magnetic stirring device of the brand IKA with a temperature sensor (PT 1000) or a device of the brand Heidolph, with or without a temperature sensor. The market costs of the devices are around CHF 1000.-. Also new are the lifts (Laborboys).
Please treat these valuable devices carefully and remove spilled chemicals immediately with water and soap. Please do NOT use aceton, alcohol, etc.
On the left side of the magnetic stirrer you will find an engraved number. The last three digits correspond to the number of the stacking container and the laboratory place number. These numbers must match each other at hand-over.
The equipment must be returned, well cleansed, at hand-over. A post-cleaning of the material to be carried out by us will be charged to your personal semester bill!
Please report all defects on devices during the semester to the HCI-Shop. We will provide you with
replacements.
The photograph shows the arrangement of the equipment at the beginning of the semester. This is
how it should look like at the end of the semester.
- 17 -
Instruction manual for the IKA magnetic stirrer (short version)
Error codes of the IKA magnetic stirrer Errors occurring while the device is running are printed on the display (E and F). Please proceed as follows:
Switch off the device > Take corrective action > Re-start the device
If the error can’t be eliminated as described above or if another error code is displayed, please contact the
HCI-Shop.
- 18 -
Administrative Registration
You should register early enough, however the latest two weeks prior to semester start electronically at: http://www.mystudies.ethz.ch or https://shib-p1.bi.id.ethz.ch/myStudies/
You we will be regarded as legally registered only if you inscribe electronically! For practicals requiring space allocation you are advised to stick to the above mentioned deadline, if you want to be sure there is lab space reserved for you at the start of the practical.
In case you will not attend the practicals, please sign off at the beginning of the semester at the HCI-Shop. You will also need to sign off at the HCI-Shop if you discontinue the practicals prematurely. In this way you will avoid the transfer of the overall costs of the practicals to your bill.
Take-over of Lab space
Students will be provided with necessary information by the responsible demonstrator.
In this information booklet for students you will find check lists for your corresponding semester as well as drawings of glassware and a retractable safety information sheet in the middle of the brochure. Please read carefully and preserve it!
The key to your laboratory space and wardrobe will be handed over to you at the counter of the HCI-Shop or by your assistant. For every key which you collect at the shop, a deposit of CHF 50.- will be booked to your account. For every key that is not returned, the deposit will be billed to you at the end of the semester. Take care, in your own interest, that you return all the keys.
In case you should forget your key, a second one is available at the shop. In case you break a key you will be given a second one, free of charge, in exchange for the broken key at the HCI-Shop. Don’t throw away the broken key! We would have to charge the same deposit to your account as in the case of a lost key.
Please check the available glassware at your laboratory space and confirm its completeness with your signature on the separate acknowledgment of receipt form. Missing or defective glassware will only be replaced/exchanged on the date of laboratory space takeover.
After handing in the acknowledgement of receipt form at the HCI-Shop counter you will be given your customer card. Students who do not need glassware sets for practicals, will be given their customer card and possibly a wardrobe key at the HCI-Shop. Some of the wardrobes will indeed need a padlock. Padlocks can be purchased, but not borrowed, at the HCI-Shop.
Customer cards for the HCI-Shop will be prepared for each student. During the semester, in order to avoid problems with accounting, equipment may only be purchased with the customer card. Students may purchase lab supplies, glassware and office materials with their customer card. Students are not allowed to purchase chemicals with their customer card! Chemicals are handed out to students only upon approval of a demonstrator - authorized by signature.
Lab space handover
At the end of the practicals, please check with the help of the already known acknowledgment of receipt whether your glassware is complete.
Missing or defective ware must be replaced before the handover. We reserve the right to inspect the glass sets during the return, randomly for the 1st semester and every glass set for higher semesters. Please place the acknowledgment of receipt with the glass set.
Please make sure that your IKA or Heidolph magnetic stirrer has the right number. After the handover of the glassware in the storage room (C294.1) of the HCI-Shop, please also return your lab space key and your customer card at the counter of the HCI-Shop.
- 19 -
ATTENTION: Do not forget to completely clear the wardrobe of personal belongings and wastes prior to the handover. Please make sure that all electrical devices and material goods (photograph page 16) are in the equipment box (= stacking container with lab place number). Please do not place any glassware in this container. The equipment box is the first box, which you should handover during the return of the glassware. Please beware of this sequence when transporting the boxes to the storage room (C294.1). Please hold the burettes, pipettes and thermometers separately, as they have to be handed out first, at the return in the storage room (C294.1), even before the equipment box.
Invoice for the practicals fee and the HCI-Shop purchases
At the end of the semester, in consultation with the demonstrators, the students’ participation in the practicals will be checked.
Note: Every student participating in a practical will get a bill! Glassware, lab supplies and chemicals are required during every practical, also if the experiments are only carried out by the demonstrators. The accumulating costs are charged to a practicals account in the HCI-Shop and are divided proportionately amongst the students at the end of the semester. Fluctuating chemical prices and changing numbers of participants at the practicals lead to differences in the amount billed to the students from semester to semester.
The fee for the respective practical will be charged to your HCI-Shop account. Thereafter, the data
will be forwarded to the finance department and from there, the bills will be sent to the students.
The following items will usually be charged to you:
Deposit for every wardrobe key that is not returned at the end of the practicals.
Personal purchases on your HCI-Shop account, e.g. box with lab supplies for practicals
for the 1st semester, issued scripts, glass breakage replacement for defective loan
material.
Share amount “material from the demonstrator”; the head of the practicals determines
the amount.
Share amount protection goggles Fr. 8.-
You can get details to your bill and to your HCI-Shop account directly from the HCI-Shop or via the mail address listed on the bill. For questions about payment transactions (e.g. cancellation of incorrectly transferred amounts, confirmation of bookings and transfers) please contact the ETH finance department directly at [email protected].
Reminder
If a bill is not paid by a student, a reminder will be issued! As a student you have the possibility to view your reminder levels. Should someone have several open bills, the highest reminder level will be displayed. Already as of the first reminder level, you won’t be able to register for the next semester. Your “myStudies” account will be partially blocked. It is advisable to settle the bill quickly and to follow up any problems immediately. The reminder status will be activated the day after the booking, this means, after paying the bill the reminder level will not immediately be refreshed.
Safety: Night and continuous operation board for Overnight Experiments
Experiments and devices without high safety risks, running overnight, must be declared via a night board. The night board must be clearly, visibly attached to the chapel window, respectively close to the experiment or installation. General night boards are not allowed; each experiment needs a new board. Devices under continuous operation must be specially labelled with the phone number of the responsible person in as well as with hints for behavior in case of emergency. Devices running without a night board will be switched off between 22:00 and 06:00 on weekends, bank holidays and during the week. https://www.ethz.ch/content/dam/ethz/associates/services/Service/sicherheit-gesundheit-

Dear Students
Please, for safety reasons, transport all your chemicals
in a transportation basket with safety insert!
No basket, no chemicals! Thank you.
Don’t forget: Always remove your gloves, before leaving the lab!
