AB  - ABSTRACT: When monitoring the microbiological quality of air in unidirectional air flow units the Biotest air sampler Reuter Centrifugal Sampler (RCS) is often used. In this unidirectional air flow the dispersion region of contaminants (disturbance region caused by turbulence) around the RCS sampler is much larger than that of undisturbed parallel air flow. The recently developed air sampler from Biotest, the RCS +, has a smaller and a different type of dispersion region (disturbance region) than that of the common RCS sampler. The differences must be taken into consideration when the two types of RCS air sampler are used within unidirectional air flow units, especially during aseptic operations in pharmaceutical production.
