The use of HettCube incubators and cooled incubators for colony counts in drinking water

Drinking water has to satisfy strict requirements in terms of the micro-organisms it can contain. The total number of culturable micro-organisms is one parameter that has to be determined. The colonies that are to be counted include those isolated from humans and animals as well as those found in the soil or water. The results of such colony counts allow inferences to be drawn on the nature and origin of the colonies. 1ml water must not contain more than 100 colonies.
