1. TEST TUBEUsed for heating and

mixing small quantities of chemicals

2. BEAKERUsed for heating and

mixing large quantities of chemicals

3. FUNNELUsed to transfer

liquids and powders from one container to another

4. ERLENMEYER FLASKUsed for dissolving and

mixing chemicals which must be protected from unnecessary air contact; mix by gently swirling; identified by its tapered sides and flat bottom.

5. FLORENCE FLASKUsed for boiling and

distilling; identified by its round bottom.

6. FORCEPSUsed to pick up

objects to avoid contact with one’s hand; looks like tweezers

7. TEST TUBE HOLDERClamps onto the test

tube and is held in the hand to support the test tube in mixing and heating.

8. TEST TUBE BRUSHIs inserted into the

test tube to clean the test tube.

9. RUBBER STOPPERUsed as a top on

various kinds of glassware; can be solid or with 1 or 2 holes.

10. GRADUATED CYLINDER

Used to measure liquid in milliliters.

11. RING CLAMPMetal rings used to

hold a funnel or to support glassware over a flame.

12. RING STANDUsed to hold ring

clamps and test tube clamps

13. GLASS STIRRING ROD

Slender piece of glass used to mix chemicals

14. METRIC RULERUsed to measure the

length of flat surfaces that can not be bent. Measure in centimeters or millimeters.

15. PETRI DISHUsed to hold objects

for observation

16. DROPPERUsed to measure

drops of a liquid.

17. TRIPLE BEAM BALANCE

Used to measure mass. The unit is in grams.

18. HAND LENSHeld in the hand and

used to make objects appear larger so that small details are easier to see.

19.BUNSEN BURNERUses natural gas to

provide a flame in the lab.

20. MICROSCOPEUsed to see small

things that cannot be seen with the naked eye or hand lens

21. TEST TUBE CLAMPUsed to hold a test

tube over a flame by attaching it to the ring stand.

22. THERMOMETERUsed to measure

temperature in degrees Celsius.

23. DISSECTING PANA tray that is used to

contain the specimen while dissecting

24. DISSECTING PINSUsed to secure the

specimen onto the dissecting pan to ensure no movement.

25. SCALPELExtremely sharp

dissecting tool used for slicing the specimen.

26. SCISSORSUsed to cut the

specimen while dissecting.

27. DISSECTING NEEDLE

Dissecting tool used to hold or scrape the dissecting specimen.

28. SPRING SCALE

Equipment used to measure force in newtons.

EYE WASH STATIONprovided in all labs to

flood eye with water for 15 minutes to remove foreign materials and to dilute any harmful chemical.

FIRE BLANKETUsed to smother out a fire,

can be used to wrap around an individual, smother a table surface fire, or smother a fire in a waste basket.

FIRE EXTINGUISHERused to put out small

chemical or paper fires. In case of major fires, signal alarm and evacuate building, using fire drill procedures.

SAFETY GOGGLESThey are vital to the safety of

your vision. Wear them when heating,

when working with chemicals or at any time you are instructed to do so by your teacher.

MATERIAL SAFETY DATA SHEET

contain important information about the chemicals you use in lab.

LAB APRONrubber coated and acid-

resistant, alcohol-resistant and has a better oil-resistance than natural rubber
