SAS Microbial Monitoring Equipment

Hand Held Air Samplers - Isolator Sampling - Compressed Air Sampling - Multi SAS System - Air Sampler Calibration

Cherwell has been supplying the UK market with the SAS range of microbial air samplers for over 30 years. The SAS air sampler range includes a wide selection of portable hand held units, a compressed air sampling device and an isolator specific unit, all of which provide benefits for specific environmental monitoring purposes. Our expertise is primarily focused within the pharmaceutical and related industries, however, microbial air monitoring is increasingly being used for evaluating hospital operating theatres, office ventilation space and food manufacturing.

SAS air sampling units use the multi point impaction (single stage sieve) sampling technique and sample air at a fixed rate. Air borne particles are impacted onto the agar surface of a standard Contact plate, with Petri dish versions also available.
