Product Description
25mm Asbestos Air Sampling Cassette with 0.8µm MCE Filter – PCM Applications
Zefon 25mm air sampling cassettes are precision-manufactured for regulated asbestos fiber monitoring using phase contrast microscopy (PCM) and compatible TEM workflows. Each cassette housing is injection-molded in-house, individually assembled, serialized, and tested to deliver consistent, defensible laboratory results for industrial hygiene professionals and environmental consultants.
This configuration includes a 0.8µm mixed cellulose ester (MCE) filter, a three-piece conductive cassette, and is packaged 50 cassettes per box, preloaded and ready for immediate field deployment.

Independent Quality Verification
Every cassette undergoes 100% inspection confirming the correct filter/pad combination and ensuring no parchment paper remains inside the unit.
Each production lot is independently tested through blank sample analysis to verify acceptable background fiber counts per NIOSH standards.
Daily random-lot testing provides added assurance for consultants, laboratories, and remediation contractors. Documentation is available upon request.
