Consistent Performance for
Industrial Hygiene Sampling

• 37 mm diameter meets NIOSH and other regulatory requirements for industrial hygiene sampling using vacuum filtration.
• 0.8 μm GN-4 Metricel® membrane has a low fiber background count.It is widely accepted for air monitoring of fibers, asbestos fibers, and metals.
• Choose from two- or three-piece units.
• Disposable after a single use or may be reused.

• Designed to meet NIOSH and other regulatory requirements for industrial hygiene sampling.
• Ideally suited for particulate and air sampling analysis using vacuum filtration.
• Cassettes can be used to monitor respirable constituents such as nuisance dust, silica, aerosols, and airborne particulates.
• For open- or closed-face monitoring methods.
