Membrany GLA-5000 PVC
Membrany o niskiej zawartości popiołu idealne do wielu metod analitycznych NIOSH
GLA-5000 PVC membrane disc filters, a Pall Life Sciences product, are inherently low ash membranes well suited for multiple NIOSH analytical methods.

Assures gravimetric stability with 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 Air Monitoring Cassettes.
