Make air sampling fast and simple with preassembled, preloaded filter cassettes. Cassettes come preloaded with MCE membrane filter, a mixture of cellulose acetate and cellulose nitrate, which is one of the most widely used filters in air monitoring and analytical applications. Select from 25-mm or 37-mm diameter membrane filters with various housing materials and features to meet NIOSH, OSHA, and EPA standards. Cassettes are preloaded in an ISO 9001:2015-certified facility, ensuring high quality control standards.

Clear styrene housing lets you view the filter media while conductive black polypropylene (PP) housing is ideal when wall deposit is a concern. Models with band provides added leak protection as well as offer a place to write notes. To ensure tamper resistance, select model with security band that goes over the end plugs.
