Vortexer
Quickly mix all kinds of solutions with the affordable vortexer. Sturdy, quiet unit is efficient, minimizing excessive vibration and noise. Operate continuously or by touch with a “push top to start” feature. Suction feet keep the vortexer stable, eliminating any “walking” across the lab bench. Variable speed control from 200 to 3200 rpm. Compatible for cold rooms or incubators and has spill-proof electronic controls. 13 x 16 x 17 cm. 2-year warranty.

DNA Isolation—Student Laboratory Kit
The procedure for securing student cheek cells is safe and requires only a rinsing of the mouth with water. Isolating “personal” DNA adds a great deal of student interest to
a lab that otherwise might be less than exciting. Note: The procedures detailed in this kit can be used to “spool” DNA from many different sources other than cheek cells. Complete for 30 students working individually.

UV Light Transilluminator
A safe and effective way to view DNA at a reasonable price! This midrange UV transilluminator is optimized to visualize DNA bands stained with either ethidium bromide or SYBR® Safe. The UV filter measures gels up to 7 x 14 cm. The UV-blocking cover protects users from the UV light and the lamp turns off automatically if the cover is opened. 7 x 14 cm viewing area.

A Process to Dye for: Gel Electrophoresis— Student Laboratory Kit
Introduce your students to the basic principles and operation of gel electrophoresis with this quick and easy experiment using colorful dyes. Students learn how biological molecules are sepa- rated during electrophoresis by comparing the charge, size and molecular formulas of five dyes. Students observe the direction and measure the rate of migration of the dyes and then use the results to identify an unknown mixture of dyes. The use of dyes eliminates the need for staining the samples, which means the entire process can be completed in one class period. Materials provided include agarose gel in a melt-and-pour bottle (suffi- cient to make 10 gels), TAE buffer, dye samples, microcentrifuge tubes, needle-tip pipets, and rulers, plus complete instructions. Complete for eight student groups.
