Thing to consider should also be specified to your timeliness of microbial enumeration testing right after sample collection. The quantity of detectable planktonic microorganisms inside a sample gathered in the scrupulously thoroughly clean sample container will usually fall as time passes. The planktonic germs throughout the sample will tend to either die or to irretrievably adsorb for the container walls minimizing the number of viable planktonic microbes which might be withdrawn through the sample for testing.
