Single Stage N6 Viable Anderson Cascade Impactor System 220V with Pump & Case SKU: TE-10-890X

The TE-10-890X is a single-stage Anderson cascade impactor designed for collecting and analyzing airborne aerosols containing bacteria or fungi. Constructed with precision-tooled aluminum components held together by three spring clamps and sealed with O-ring gaskets, the impactor stage contains 400 precision-drilled orifices. This complete sampling system includes an integrated 220V vacuum pump, making it ideal for field deployment and laboratory applications.

Operating Principle

Air to be sampled enters the sampler and accelerates through the jet orifices of the classification stage where smaller particles are inertially impacted on the agar plate. Viable particles are retained on the agar plate while exhaust air is carried through the outlet in the base of the instrument to the vacuum source. Petri dishes containing an agar medium are placed in the instrument and air samples are drawn through, collecting corresponding particulates at each stage on the agar medium before removal for incubation and counting.

Applications

The 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. Applications include monitoring airborne microbial contamination in operating theaters and healthcare environments, as well as industrial hygiene assessments, environmental monitoring, and bioaerosol research.

Maintenance Notes

Requires a flow rate of exactly 28.3 L/min for maximum collection efficiency. Regular calibration verification is recommended to maintain sampling accuracy. Colony counts should be corrected using the positive-hole correction method to account for multiple bioaerosol particle deposition at the same area. The aluminum construction allows for autoclave sterilization between sampling events.
