BioStage

The BioStage single-stage cascade impactor operates on the principle of inertial impaction and meets NIOSH requirements and ACGIH recommendations for sampling indoor and outdoor air for viable microorganisms including bacteria and fungi. Made of precision-tooled aluminum, the sampler components are held together securely by the SureLock positive seal. Using a high flow pump such as the BioLite, air is drawn through the impactor where particles are impacted onto an agar collection medium.

BioStage
  • Easy to use
  • Made of corrosion resistant aluminium and autoclavable
  • Collected organisms remain intact and viable
