These 37 mm, 0.8 µm pore size MCE (Mixed Cellulose Ester) 3‑piece cassettes commonly used in industrial hygiene air sampling.

The cassettes are widely used for exposure assessment to heavy metals, lead, manganese, cadmium, welding fumes, and metal shavings, as well as other particulates generated in industrial processes. They are compatible with standard aluminum and nylon cyclones for respirable fraction sampling and are routinely selected for laboratory analysis by ICP or AAES following methods such as NIOSH 7300, OSHA ID‑121, and comparable elemental analysis procedures. Their construction supports efficient digestion and extraction, contributing to consistent analytical recovery. They are not pre‑weighed, making them suitable for applications where gravimetric analysis is not required and where the primary objective is the collection of airborne metals and fine particulate matter.

For best performance, the cassettes should be stored at room temperature before and after sampling to prevent moisture‑related changes in the filter media. Keeping them sealed until use helps minimize contamination and ensures reliable sample integrity during field collection and laboratory analysis.
