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. 


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. 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 chrysotile asbestos. Sterlitech's silver metal membranes can be used as the collection media and subsequent x-ray diffraction substrate for quantifying unknown minerals and compounds. Start with a custom silver membrane sample pack here. We provide the filters and technical support to help you take your breakthrough product from an idea to a prototype, to commercial scale.

Applications

Sterlitech™ Silver Membranes can be used for a wide variety of industrial hygiene, OSHA and laboratory applications.

Analytical

  • X-ray diffraction (XRD); silver metal membranes make excellent substrates for XRD analysis - silver purity 99.97% -- smooth surface, grayish-white color; highly reflective surface; absolute surface retention; low background noise; distinct diffraction peaks.
  • Scanning Electron Microscopy (EM); smooth; electrically conductive; extremely thin membrane 50 µm; easy sample preparation.

Gas

Liquid

  • Clarification (3.0-5.0 µm); Polishing (1.2 µm); Sterilization (0.2-0.8 µm)
  • Intrinsically Bacteriostatic - Silver does not allow the growth of bacteria and other microorganisms.
  • High-Performance Liquid Chromatography (HPLC) for a clearer; steadier baseline - may rule out interference from other sources of HPLC solvents (0.2, 0.45, and 0.8 &micor;m); tolerates high temperatures; gases and aggressive liquids -- Tetrahydrofuran (THF)

 

Viscous Fluid

  • Organic Carbon, inorganic, and suspended-sediment water - 0.45 µm, 47 mm, used by U.S. Geological Survey (USGS)
  • Lubrication oils for servomechanisms and precision instruments
  • Direct-line Applications with a Sprayer
  • High-purity fluids in semiconductor applications

Other Industrial

  • Chlorine Monitoring - Pulp and Paper Industry, disinfection; removal of tin and zinc in iron; chlorinating hydrocarbons; manufacturing synthetic rubber, plastics, pesticides, refrigerants; treating water and sewage
  • Electronics Industry - filter coolants, cleaning fluids, sterile air
  • Aircraft/Missile Fuels; critical fluids - resists alcohols, fuels, hydrocarbons, polyaromatic hydrocarbons (PAH), oils, alkalies, ethers
  • OSHA - coal tar pitch volatiles, 0.8 µm, 47 mm and 37 mm
  • Cold Sterilization (beverages, beer) - absolute particle-retention due to precise pore size
  • Soil and clay analysis
  • Fly Ash Sampling; Energy Research and Development Agency (ERDA)
  • Bacteria Sampling
