Microbial Air Sampler 100 LPM Flow Rate

The Microbial Air Samplers have a stainless steel enclosure that is Pharmaceutical / Industrial Grade Drop & Vibration Tested. It is an active air microbial sampler used in either sequential or continuous monitoring applications in aseptic areas. The Climet CI-9xA & NEW CI-97 Series of microbial samplers are designed and built with the same ruggedness users have to come to expect in Climet particle counters. It is the only pharmaceutical grade microbial air sampler that meets and exceeds all requirements AND recommendations of ISO 14698, as well as augmented by some requirements in ISO 21501-4. The NEW CI-97 also includes FDA 21 CFR PART 11 – Advanced Data Integrity Features.

CI-97 Series CI-90A Series

CI-302 High Pressure Diffuser

The CI-302 High-Pressure Diffuser is used to sample high-pressure gases with Climet particle counters or microbial air samplers. The CI-302 works by regulating the flow rate with an external port to provide a path for the excess pressure. Allows the instrument to “pull-in” the gas and control the flow rather than blast the gas through the unit.

Adapter Heads- 

In combination with the high pressure difusser, the CI-9xA Adapter Head allows for you to sample your high pressure gases for viable particles. Used in the CI-90A & CI-95A
