AirPrep™ Cub Sampler

InnovaPrep engineers have developed a new, compact model of the Bobcat Air Sampler trusted by researchers and US military since 2012.
Using the same 360° aerosol inlet design and rapid filter elution kit, the AirPrep Cub Sampler is just as efficient for the collection and recovery of bioaerosols and particulates from 0.01 microns to 10+microns.  

The AirPrep Cub Sampler uses a 52mm dry electret filter as the collection media. Electret filters are produced from dielectric polymer fibers that develop an electrical charge when air flows past them. This substantially increases the collection efficiency of the filter allowing efficient collection of the smallest diameter viruses which is a limitation of most competing collectors. The AirPrep Cub Sampler efficiently captures micron- and submicron-sized particles, including viruses, bacteria, pollen, molds and fungal spores, as well as non-biological particles from 0.01um to 10um+.

The system uses a dry 52 mm electret filter as the collection media. Electret filters are made with a combination of positively and negatively charged fibers which substantially increases the collection efficiency and allows for the use of lower pressure drop filters which, in turn, allows for higher sampling rates for extended periods using battery power. Because no fluids are used in the system, it can operate at low temperatures; a limitation for most wet-wall cyclone type collectors.

Rapid sample recovery from the filter

The single-use filter and elution kit comes with everything you need for rapid sample recovery including: sample cup and lid, elutor adapter, and elution foam canister.

Following aerosol collection, the filter is removed from the collector, snapped onto the sample cup and fitted with the elutor adapter. To extract the captured particles from the filter, the user presses the canister containing the Wet Foam Elution™ into the elutor adapter. The elution foam is released from the canister evenly through the filter. The wet foam passes through the interstitial spaces of the filter to efficiently extract any captured particles. Sample elution takes approximately 5 seconds and produces 6 to 7 milliliters of liquid sample. The foam immediately collapses back to a liquid in the sample cup, making it available for sample processing and analysis.
