Silver metal membrane filters are used in a variety of filtration applications. Their ability to withstand extreme chemical and thermal stress makes them ideal laboratory filtration equipment for applications involving aggressive fluids and/or high temperatures. Silver metal filters are constructed with pure metallic silver (99.97%) and are specified in a National Institute for Occupational Safety and Health (NIOSH) standard for the analysis of crystalline and amorphous silica, lead sulfide, boron carbide, and chrysotile asbestos. Silver metal membranes can be used as the collection media and subsequent x-ray diffraction substrate for quantifying unknown minerals and compounds.
