Filter, Silver Membrane w/o support pad, 0.8µm, 25mm, 50Pk
Part Number:
225-1803
Overview
Silver Membrane Filter, 0.8 µm, 25-mm, no support pad included.
Made of 99.97% pure inorganic metallic silver, SKC Silver Membrane Filters are chemically inert and resistant to high temperatures for sampling aggressive contaminants. Their smooth surface provides for high surface capture of particles and easy observation. Silver Filters are ideal for X-ray diffraction and other analyses for crystalline silica, lead sulfide, boron carbide, and chrysotile asbestos. Environmentally friendly Silver Filters can be cleaned and reused for most applications.
