Product Description

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


  • 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.


  • Air-borne contaminants - National Institute for Occupational Safety and Health (NIOSH) - used for industrial hygiene in foundries, glass plants, quarries, mines, ceramic manufacturing - Methods using 0.45 µm, 25 mm:
    • N6011 (Bromine and Chlorine)
    • N7500 (Silica, Crystalline)
    • N7501 (Silica, Amorphous)
    • OSHA ID142 (Quartz and Cristobalite in Workplace Atmospheres)
    • N7504 (Vanadium Oxide)
    • N7505 (Lead Sulfide)
    • N7506 (Boron Carbide)
    • N9000 (Asbestos, Crysotile)
  • Respirable Combustible Dust (RCD) sampling and analysis - 0.8 µm, 25 mm, mines - measurement of diesel particulate matter, evaporated hydraulic fluids, fuel oils, and compressed air lubricants by weighing and ashing.
  • Dopant gases for semiconductor manufacturing.
  • Steam, or air sterilization, autoclavable
  • Venting, high temperatures


  • 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
