RIPPLE TANK

Item No. DescriptionRPLTNK1 Ripple Tank

This outstandingly versatile transverse wave machine consists of aseries of pendulums independently suspended on a common baseand coupled together by long, light springs. It has two moduleswith 21 pendulums each, a damping unit with a paddle andwater bath, and a motor-powered eccentric driver for controlledexcitation of traveling or standing waves. The ends of thependulums are bright yellow for excellent visibility of the wavepattern. Coupling hardware is supplied so that the Demonstratorcan be used with either a single module or with both modulescoupled to make a longer machine. A brake mechanism allowsall the pendulums to be arrested simultaneously, "freezing" themomentary pattern of the pendulums. Basic phenomena intransverse wave propagation can be clearly shown. Using thedamping module, running waves can be generated and standingwave patterns, wave reflection, and superposition can be shownwhen the damping module is removed.

MITOSIS MANIPULATIVES KIT

Item No. DescriptionMITKIT Mitosis Manipulatives Kit

Teaching meiosis presents challenges for both teaching andlearning because it is an abstract concept that requires visual andtactile models for most students to conceptualize. The exchangeprocess of maternal and paternal alleles during cross-over isespecially difficult without such a reference. A lot of time wasspent designing, testing and refining this kit in classrooms to meetyour needs. This kit will make teaching and learning meiosismuch more enjoyable for you, just as it has for others. The kit includes:• Teacher Demonstration Models: Thirty large chromosomesarranged in five colorful sets that can be seen on your board fromthe back of your classroom. Each set consists of a maternal andpaternal homolog and four sister chromatids Alleles and parentallineage are clearly identified. The fifth set has removable allelesfor demonstrating cross-over.

• Student Models: Students carry out teacher directed assignmentsat their desk using their own smaller sets of chromosomes. Thereare no consumables so the kit can be used over and over again. • Instructional CD and Teacher Manual: We will walk you thruusing the kit for the first time in an easy, familiar and pictorialslide show fashion. Don’t worry if this is your first time teachingmeiosis because absolutely everything you need is in the kit.Recommended student activity and assessment options are alsoincluded.

Pipettes are manufactured from specially selected heavy-wallmachine-drawn borosilicate accurate bore glass tubing. Theyhave precision formed jets and bevel ground ends to resistchipping. The graduation marks are in durable white enamel oramber stain, both are resistant to normal laboratory agents andrepeated washing. All the pipettes are individually measured andthen marked. Accuracy is ensured between any two readings,because of uniformity of bore. The pipettes can be autoclavedand if necessary can be flamed for sterilization.

Physical Properties of United Glassware

CHEMICAL COMPOSITION

• Our glassware is manufactured from low alkali Type 3.3

borosilicate glass. It is virtually free of magnesia-lime-zinc group

and is completely free of arsenic and other heavy metals.

THERMAL PROPERTIES

• Our low expansion borosilicate glass can be used for

applications up to 500°C. It can withstand higher temperatures

and sudden changes in temperature/thermal shocks. Minute

scratching of the surface can reduce its thermal resistance

CHEMICAL DURABILITY

• Our glassware is highly resistant to water, neutral and acid

solutions, concentrated acids and their mixtures as well as to

chlorine, bromine, iodine, and organic matters. During

extended periods of reactions and at temperatures above

100°C, its chemical resistance exceeds that of most metals and

other materials. It can withstand repeated sterilization.

OPTICAL PROPERTIES

• Our glassware shows no noticeable absorption in the visible

region of the spectrum, thus is clear and colorless.

For additional information regarding thermalproperties and chemical durability pertaining to your

specific application, please contact us.

TEST TUBE BASKETS

High-quality borosilicate glass test tubes.
