A dipslide is a means of testing the microbial content of liquids. This is a common method of monitoring and measuring microbial activity within many systems and commonly cooling systems. Usually the use of a dipslide is the first line of defence for the testing of microbial issues that could be caused to manufacturers and machine shop fluid systems.
Dipslides consist of a plastic barrier which bears a sterile culture medium which can be dipped into the liquid being sampled. The resulting microbial colonies are estimated by reference to a chart.
Dipslides are usually incubated for 48 hours after use and any subsequent bacteria in the sample water will grow and form colonies.
