Product Description
25mm Asbestos Air Sampling Cassette with 0.8µm MCE Green Grid – 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 hygienists, laboratories, and remediation professionals.
This configuration features a 0.8µm mixed cellulose ester (MCE) filter with green 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 to confirm the correct filter/pad configuration and verify that no parchment paper remains inside.
Each production lot is independently tested through blank sample analysis to ensure acceptable background fiber counts per NIOSH requirements.
Daily random-lot audits provide added confidence for consultants and laboratories. Test documentation is available upon request.
Why Green-Grid PCM Cassettes Matter
