The kit comprises a simple sterilized plastic or glass bottle that contains dry powder medium. The powder is completely soluble in water and a dark amber colour solution is formed on the addition of water.
This is a simple bacteriological testing kit that could be used to indicate the presence of pathogens. It does not attempt to identify the pathogens.
The kit can be used with any water irrespective of its source, including chlorinated water.
The solution will change colour to black in the presence of H2S producing organisms in ambient temperatures between 25ºC and 44ºC, preferably to be kept at 35-37ºC, for an observation time of 24 to 48 hours. No incubator is needed for this range of temperatures.
