Product: BioStage - Single-Stage Viable Cascade Impactor

Easy to use

Corrosion-resistant aluminum

  • Autoclavable

Collected organisms remain intact and viable

SureLock positive seal ensures sample integrity

Easy setup and calibration

Proven principle of operation

  • Meets ACGIH recommendations for bioaerosol sampling
  • Meets NIOSH Method 0800 and 0801 requirements
  • Performance equivalent to Andersen N-6 and Aerotech A6‡


The BioStage® single-stage cascade impactor operates on the principle of inertial impaction and meets NIOSH 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 QuickTake 30, air is drawn through the impactor where particles are impacted onto an agar collection medium.

Methicillin-resistant Staphylococcus aureus (MRSA) infections occur typically in hospitals, elder and child care facilities, gyms, schools, and jails. A 2008 IAQA presentation** recommends a viable cascade impactor (such as the SKC BioStage) with ChromAgar for sample times of 2 to 5 minutes for sampling MRSA in air and sterile swabs for sampling MRSA on surfaces where the superbug can live for weeks to months.


BioStage 200 with SureLock

In addition to the standard BioStage, SKC offers the BioStage 200 with a 200-hole jet classification stage. Designed to cut the sampling job in half, BioStage 200 accommodates a 90 to 100-mm agar plate and requires only a 14.15 L/min flow rate.
