Applied microbiology in Cleanroom

Air samples are quantitatively accurate. Microbiology is an exact science. Contamination detect by an active air samplers means that the product made at the same time is contaminated. Air sampling devices are generally equal in their ability to detect contamination. Statistic + sampling plan analysis are suf cient to enable the manager to create a formula for determining “accept/reject” of a product lot. Microbes will survive forever in a cleanroom unless killed by a disinfectant.
