The Allergenco-D air sampling cassette was developed for the sampling and collection of aeroallergens and bioaerosols for quantitative analysis of mold spores, pollen, skin fragments, insects, dusts, and other airborne particulates. It has a well-designed impaction trace and collects at a standard rate of 15 liters per minute for durations ranging from one to 20 minutes. Compatible with traditional vacuum pumps, as well as most portable units. Connect to a vacuum source with either a ½” or ¼” converter or directly with ¼” tubing.
