Zefon 25mm 3-Piece Air Sampling Cassettes – Reliable Accuracy for Lab Professionals
Maximize your environmental testing precision with Zefon 25mm 3-Piece Air Sampling Cassettes. Designed to meet the stringent demands of laboratory technicians, industrial hygienists, and occupational safety professionals, these cassettes provide an uncompromising defense against sample loss and contamination.
Whether you are conducting asbestos air monitoring (PCM/TEM), gravimetric dust analysis, or ambient air testing, Zefon’s leak-free injection-molded housings ensure maximum sample integrity from the field to the lab. The versatile 3-piece standard configuration features a spacer ring that supports both closed-face and open-face sampling applications, giving your lab team the ultimate flexibility across diverse testing protocols.
Key Features & Technical Benefits
Optimized 3-Piece Configuration: Includes a dedicated spacer ring separating the inlet from the filter media, offering superior versatility for open-face and closed-face sampling, and seamless compatibility with aluminum cyclones.
Leak-Free Sample Integrity: Precision-engineered in-house molding eliminates the risk of bypass air or sample bypass, ensuring your background data remains clean and legally defensible.
Stringent Quality Control: Each lot undergoes meticulous quality checks to ensure minimal background fiber counts, fully supporting compliance with NIOSH, OSHA, and EPA standards.
Traceable Security: Every cassette is preloaded and clearly marked with a unique tracking serial number for flawless chain-of-custody documentation.
Applications
Asbestos Abatement Monitoring: Ideal for standard Phase Contrast Microscopy (PCM) and Transmission Electron Microscopy (TEM) methodologies.
Industrial Hygiene & Air Quality: Perfect for monitoring respirable crystalline silica, nuisance dust, and heavy metal particulates.
Gravimetric Analysis: Designed for reliable pre-weighed or match-weighed testing environments requiring meticulous weight stability.
