Product Description
25mm Asbestos Air Sampling Cassette with 0.8µm MCE Grid – PCM Applications
Zefon 25mm air sampling cassettes are engineered 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 support consistent, defensible laboratory results for industrial hygienists and environmental consultants.
This configuration includes a 0.8µm mixed cellulose ester (MCE) filter with grid, a three-piece conductive cassette, and is packaged 50 cassettes per box, preloaded and ready for immediate field use.

Independent Quality Verification
Every cassette undergoes 100% inspection confirming the correct filter/pad configuration and ensuring no parchment paper remains inside.
Each production lot is independently verified through blank testing to confirm acceptable background fiber counts per NIOSH requirements.
Daily random-lot sampling adds further assurance for laboratories, consultants, and remediation contractors. Test documentation is available upon request.
Why Professionals Choose Grid-Marked PCM Cassettes
