Dependant upon the cleanroom classification, there can be extremely stringent requirements on the end result of environmental monitoring.

The leading notion of test for sterility relies on The truth that if microbes are inoculated in a transparent medium which supports their growth (i.e., the best possible temperature, pH, nourishment, and h2o), the presence of microbes might be detected by improve in turbidity of medium, supplied that the test is carried out in uncontaminated conditions.
