The BioCaptImpactor Active Microbial Air Sampling Atrium enables the capture of microbiologically viable particulates on a suitable media surface for later incubation and enumeration. The slits in the BioCaptImpactor are precision cut to ensure laminar flow, thus maximizing collection efficiencies for viable particles in accordance with ISO 14698-1. Biological efficiency is guaranteed by ensuring optimal impaction velocity and giving statistical control over false positive results. The BioCaptImpactor can be used in dedicated facility monitoring system (FMS) applications as a standalone microbial sample collection device or in portable microbial monitoring applications in conjunction with a sampling device, such as the MiniCapt™ Portable Microbial Sampler. Highest validated physical and biological collection efficiencies per ISO 14698-1/Annex B 316L stainless steel atrium is autoclavable Optimal slit design ensures that microorganisms are undamaged during sampling Immediate and easy detection of false positives
