"Water"

Supplier: Thermo Fisher Scientific

The Barnstead™ E-Pure™ is designed to connect directly to the tap water feed, and it can handle all of the laboratory high volume ultrapure water applications with low operating costs. This system is ideal for AA, GS, buffer preps, or as a purified feed water source for analytical instruments or labware washers.

Safe drinking water is vitally important to health. Both pathogenic and harmless bacteria can be found in the guts of mammals and birds. Testing water for every possible type of pathogenic bacteria is slow and costly. Thus, water is tested for a characteristic type of gut bacteria - the coliforms - including the familiar E. coli. Presence of coliforms is an indicator for faecal contamination. In this experiment, students test for coliforms in simulated contaminated water using colour and fluorescent reagents. They can use these same reagents to test water samples from the environment. As an extension activity, a Gram Stain test can be performed on the collected samples.
