The definition of a dipslide is a means of testing the microbial content of liquids or surfaces. It consists of a plastic carrier bearing a sterile culture medium which can be dipped in the liquid or pressed on to the surface to be sampled. It is than incubated for 48 hours at a spedific temperature to allow microbial growth. The resulting microbial colonies are estimated by reference to a chart. If the treatment programme is effective, the dipslide count will 4 be consistently low (<10 ). If a high result is obtained, the test should be repeated and the treatment programme checked. Water-i.d. dipslides for bacterial testing are provided as 10 dipslides in a box. Water-i.d. offers a variety of incubators along with the dipslide range.
