BioVigilant Products

IMD-A® systems provide clean room environmental monitoring in real time, instantly detecting microbes so you can act. Advanced optics and signal processing help reduce risk—and require no staining, reagents or human intervention. Save time and money by knowing what’s lurking in your environment.

IMD-A 300-Series Instantaneous Microbial Detection Systems

BioVigilant’s IMD-A 300 and 350 systems revolutionize environmental air monitoring for microbial contamination.

Continuous, immediate and real-time…

Using proprietary optical technology, the IMD-A system is capable of simultaneously detecting both size and intrinsic fluorescence of airborne particulates – screening for biologic particles as small as 0.5 microns.  The system offers a ready means for determining the microbial content of an aerosol sample on a particle-by-particle basis, thereby providing a continuous, real-time analysis of environmental bioburden.  This constant monitoring and effective trending deliver knowledge to act, actions that could prevent excursions from leading to the catastrophic loss of a batch. The IMD-A 300 system samples air at 1.15 liters per minute and the IMD-A 350 samples air at 28.3 liters per minute.
