BioStage FAQs

The BioStage® single-stage bioaerosol impactor operates on the principle of inertial impaction and meets NIOSH Method 0800 and 0801 specifications and ACGIH recommendations for sampling indoor and outdoor air for viable microorganisms, including bacteria, fungi, and actinomycetes. Made of precision-tooled aluminum, the sampler contains a jet classification stage and base plate precision-threaded together for a positive seal and an inlet cone. The impactor stage contains precision-drilled holes. A sample pump draws air through the sampler where multiple jets of air direct airborne particles toward the surface of the agar collection medium. Two models of the BioStage Impactor are available to accommodate two different flow rates.

Only SKC offers the SureLock positive seal advantage! The SKC Standard BioStage Cascade Impactor is constructed with the same 400-hole jet classification stage as the Andersen N-6 Impactor. However, only the SKC BioStage features the SureLock positive seal that:

• Prevents air leaks to ensure complete sample integrity
• Does not depend on spring clamps that wear out or fail
• Requires minimal maintenance

• Grain processing and transportation
• Bio-risk response

Operation
The BioStage single-stage impactors are easy to use. A barbed outlet fitting allows fast and easy connection to a vacuum pump. The SureLock positive seal keeps the jet classification stage and agar plate securely in place and prevents leakage during sampling. Sampling is as simple as sealing an agar plate inside the BioStage, connecting the impactor to a pump such as the QuickTake 30 operating at the appropriate flow rate, sampling for two to five minutes, removing the agar plate, and sending it to a qualified laboratory for analysis.


About the BioStage 200
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. Use a quiet, portable, and battery-operated 15 L/min sample pump such as the QuickTake 30 for fast, convenient sampling.

The QuickTake 30 The SKC QuickTake 30 Sample Pump is designed for easy use with the SKC BioStage and other impaction devices that require flows to 30 L/min. The mounting bracket accessory holds the BioStage Impactor securely onto the QuickTake 30 sample pump for fast setup, easy sampling, and portability.
