GLA-5000 Membrane Disc Filters

Inherently low ash membrane ideally suited for multiple NIOSH analytical methods

Assure gravimetric stability. Low moisture pick-up and low tare weight.
Low ash. Provides interference-free silica determinations.
5 µm pore size meets NIOSH and OSHA requirements.
25 and 37 mm sizes are ideal for use in Pall Life Sciences Air Monitoring Cassettes.

Excellent membrane choice for sampling airborne metals, silica, and dust.
