Cassette holder for 37 mm air sampling cassettes and Aluminum Cyclones. Made and sold in Canada

The Universal Cassette and Cyclone Holder is designed to keep air‑sampling equipment securely positioned on a worker’s collar, ensuring accurate and compliant data collection in the field. Built for compatibility with standard 37 mm cassettes and aluminum cyclones, this holder maintains the required downward‑facing orientation specified by NIOSH and OSHA methods. Its durable, field‑ready construction provides a stable mounting point that prevents accidental rotation or misalignment—two of the most common causes of compromised sampling results.
Engineered for reliability, the holder protects attached cassettes and cyclones from impacts, hose disconnections, and accidental drops, significantly reducing the risk of sampling failure. By maintaining proper placement throughout the work shift, it improves the overall success rate of air sampling by up to 25%. This makes it an essential accessory for industrial hygienists, safety professionals, and laboratories seeking consistent, defensible, and regulation‑aligned sampling performance.
