Microbial Sampler with Hepa Filtered Exhaust

The ActiveCount100H is a high-performance portable active air sampler suitable for use in cleanrooms and aseptic environments. The ActiveCount100H is ISO 14698 compliant with a d50 collection efficiency of 1 micron and HEPA filtered exhaust ports designed to avoid re-aspiration of sampled air. The ActiveCount100H offers self-adjusting flow control to ensure accurate sampling and continuous & periodic sampling modes for optimum sampling flexibility.

The impactor head, dust cover, and adjustable petri dish holder are entirely autoclavable. You will find these components easily removed and installed on the chemically compatible and sanitizable stainless steel enclosure of the AC100H.

This unit’s exhaust is HEPA filtered to ensure ActiveCount100H will not contaminate your critical environments.

The optional remote sample head minimizes disturbance of unidirectional airflow within a biological safety cabinet or laminar flow bench. The gas sample option provides the versatility needed to accomplish all your critical sampling requirements.
