Clear plates with deep uniform wells; replace beakers and test tubes in the microchemistry lab

Petrifilm provides accurate results in three easy steps: inoculate, incubate and count. Use it to determine total aerobic bacterial populations and to identify coliform levels, E. coli and other coliforms. It can also be used to enumerate coliforms plus potential pathogens in 24 to 48 hours. Shelf life is 18 months from manufacture.

A collection of some of the more popular forms of coliphage. The successful culture of coliphage requires growing in the appropriate host bacterium (available separately)

Eliminate the need for glassware and provide a semi-micro environment for conducting many experiments with this clear tray about the size of an index card. You can use Chemplates instead of test tubes, as a demonstration vessel for your overhead projector, for individual student experiments, or even as a gas generator or water reservoir. Twelve large numbered cavities are molded into the high-impact plastic. In addition, each plate has a jumbo-sized cavity and a snap-off measuring spatula. Gas collecting tubes, available separately, fit the Chemplate caps. Package of ten.
