Microbiological Sampling

Pharmaceutical pressurized gases have to meet the microbiological environmental limits / purity classes if used as process air. The requirements of the EU-guideline have to be met especially if product contact is the case. DPhE uses a microbial sampler which conducts a defined sample volume so that it impacts on agar plates. These are being taken to microbiology for further processing and counting to be evaluated afterwards.
