Product Description
25mm Asbestos Air Sampling Cassette with 0.8µm Polycarbonate Filter – PCM & TEM
Zefon 25mm air sampling cassettes are manufactured for regulated asbestos air monitoring and fiber analysis using phase contrast microscopy (PCM) and transmission electron microscopy (TEM) methods. Each cassette housing is injection-molded in-house, individually assembled, serialized, and tested to deliver consistent, defensible laboratory results in industrial hygiene and environmental investigations.
This configuration includes a 0.8µm polycarbonate filter, a three-piece conductive cassette, and is packaged 50 cassettes per box, preloaded and ready for field sampling.

Independent Quality Control
Each Zefon cassette is subject to 100% inspection verifying the correct filter and pad combination and ensuring no parchment paper remains inside the unit.
Every production lot is further validated by independent laboratory blank testing to confirm acceptable background fiber counts in accordance with NIOSH requirements.
Random daily lot sampling adds an additional safeguard for consultants, laboratories, and abatement contractors. Test documentation is available upon request.
