| Silver Membrane Disc Filter |
Sterlitech silver metal filter membranes are pure metallic silver (99.97% pure silver) and are available with particle retention ratings of 0.2 to 5.0 microns. Silver metal membrane filters are used in a variety of filtration applications, and their ability to withstand extreme chemical and thermal stress makes them ideal laboratory filtration equipment for applications involving aggressive fluids and/or high temperatures.
These silver metal membrane disc filters and sheets 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 chrystolite asbestos. Sterlitech silver metal membranes can be used as the collection media and subsequent x-ray diffraction substrate for quantifying unknown minerals and compounds. |
