Cat. #951 Chromogenic Analysis of Water Contaminants
For 10 Groups. Testing drinking water for every possible type of pathogenic bacteria is slow and costly. Thus, drinking water is tested for coliforms - including the familiar E. coli . Presence of coli- forms is an indicator of fecal contamination. In this experiment, students will test for coliforms in simulated contaminated water using color and fluorescent reagents. They can use these same reagents to test water samples from the envi - ronment. As an extension activity, a Gram Stain test can be performed on the collected samples.

Cat. #969 Long Wave UV Light
Cat. #953 Multiplex PCR-based Testing of Water Contaminants
For 25 Students. Drinking water is routinely tested for contamination. If a screening tests positive, more sophisticated tests are required. One such test uses PCR in multiplex format. In this experi- ment, students will test for the presence of three separate, classroom-safe organisms in a water sample using a single PCR reaction.
