The Bobcat is a light-weight, portable, dry filter air sampler with a unique rapid filter elution kit. It is ideally suited for the collection of micron- and submicron-sized particles, including viruses, bacteria, pollen, molds and fungal spores, as well as non-biological particles from 0.01um to 10um+. Perfectly suited for use with rapid molecular analytical methods.


  • Lightweight, only 7.8 lbs with battery
  • Built-in tripod
  • Omni-directional aerosol inlet
  • Built-in mass flow sensor for consistent sampling rates up to 200 LPM
  • 4 programmable run modes allow the user to balance collection rate with battery life. Run modes can be factory customized for flow rate and time intervals.
  • No liquids in the collector allow for use in extreme temperatures
  • Eluting captured particles from the filter takes only seconds
  • Rugged design for durability
  • Optional remote trigger is available

Rapid sample recovery from the filter

Following aerosol collection on to the dry electret filter, 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 elution buffer into the adapter initiating the Wet Foam Elution.

The wet foam passes through the interstitial spaces of the filter breaking charges and efficiently extracting captured particles. Sample elution takes approximately 5 seconds and produces ~6 milliliters of liquid sample. The foam immediately collapses back to a liquid in the sample cup, making it available for sample processing. Pairs will any analytical method and perfect for PCR and next gen sequencing.
