Meet ActiveCount… the portable microbial air sampler for cleanrooms and aseptic environments. With self-adjusting flow control and programmable settings, experience a new practical approach to routine sampling.
The monitoring plan sets the routine. Continuous, periodic, and gas sampling modes let teams select an approach that fits their process. For work that calls for a separate impactor, the optional Remote Impactor Kit is available for ActiveCount100H and ActiveCount25H. An optional compressed gas sampler supports gas sampling workflows.
ActiveCount brings self-adjusting flow control to cleanroom microbial monitoring. A portable microbial air sampler for teams working in an aseptic environment.
Regulated work calls for clearly defined sampling performance. ActiveCount100H is EN17141 compliant, with a d50 collection efficiency of 1µm. That gives your QA and validation teams documented performance to assess against their monitoring requirements.
Routine sampling should feel routine. A touchscreen puts eight programmable sampling volumes, 50 user names, and 400 locations within easy reach. Self-adjusting flow control supports accurate sampling, with flow rate alarms to flag changes that need attention. An internal battery supports 8 to 10 hours of normal use, with AC operation available for stationary sampling.
Traceability starts with the details. USB data logging records the user, location, sample volume, timing, and status, giving teams the context behind each sampling run. Password-protected sample settings help keep setup changes under control. Compatibility with the Rapid Micro Biosystems® Growth Direct System supports labs using that microbiology workflow.
Best for sampling at 25 L/min when the plan calls for a lower flow rate and HEPA-filtered exhaust.
Best for routine sampling at 100 L/min when HEPA-filtered exhaust is not a selection requirement.
Best for routine sampling at 100 L/min with HEPA-filtered exhaust.
A modular, scalable, remote accessory set ready to meet the demands of regulated cleanroom environments.

Viable sampling should fit your day, not slow it down. The ActiveCount Remote Impactor Kit gives your team a compact, modular way to sample in regulated cleanrooms, with either petri plates or Rapid Micro Bio (RMB) cassettes. Pair it with an ActiveCount25H or ActiveCount100H, or connect it to your house vacuum. Then pick the flow rate that suits the job: 10, 25, 28.3, or 100 LPM.
Tight spots are no trouble. The low-profile impactor samples from the side or the bottom, and a sanitary flange accessory makes isolators and LAF cabinets easy to reach. Every part is autoclavable, and each sample head carries a laser-etched barcode that holds up through cleaning, so tracking stays simple. Start with one location today, add more zones next month, and we’ll help you build a setup that fits your workflow.
ActiveCount is a portable microbial air sampler for cleanrooms and aseptic environments. It supports cleanroom microbial monitoring with programmable sampling and self-adjusting flow control.
ActiveCount100Hsamples at 100 liters per minute with HEPA-filtered exhaust. ActiveCount25Hsamples at 25 liters per minute with HEPA-filtered exhaust. ActiveCount100 samples at 100 liters per minute.
ActiveCount100H is EN17141 compliant, with a d50 collection efficiency of 1 micron.
ActiveCount100H and ActiveCount25H have HEPA-filtered exhaust. On ActiveCount100H, the exhaust ports are positioned to avoid drawing sampled air back into the sampler.
The sampling head, dust cover, and removable Petri dish holder on the H models are autoclavable. The stainless steel enclosure is sanitizable and supports routine wipedowns.
Yes. ActiveCount offers eight programmable sampling volumes, selectable through the touchscreen interface.
