Sterlitech Silver Membrane Filter / 실버멤브레인필터

Sterlitech Silver Membrane Filter / 실버 멤브레인 필터

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 for laboratory filtration involving aggressive fluids and/or high temperatures.
These 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 µm.
They are specified in NIOSH standards for the analysis of crystalline and amorphous silica, lead sulfide, boron carbide, and chrysotile asbestos.
Sterlitech's silver metal membranes can be used as collection media and as x-ray diffraction substrates for quantifying unknown minerals and compounds.

Applications

1. Analytical

• X-ray Diffraction (XRD): Excellent substrate for XRD analysis; 99.97% silver purity, smooth reflective surface, low background noise, distinct diffraction peaks.
• Scanning Electron Microscopy (SEM): Smooth, electrically conductive, extremely thin (50 µm), easy sample preparation.

2. Gas

• Air-borne Contaminants: Used in industrial hygiene (foundries, glass plants, quarries, mines, ceramics).
  Applicable NIOSH/OSHA methods:
  • N6011 (Bromine and Chlorine)
  • N7500 (Silica, Crystalline)
  • N7501 (Silica, Amorphous)
  • OSHA ID142 (Quartz and Cristobalite)
  • N7504 (Vanadium Oxide)
  • N7505 (Lead Sulfide)
  • N7506 (Boron Carbide)
  • N9000 (Asbestos, Chrysotile)
• Respirable Combustible Dust (RCD): 0.8 µm, 25 mm filters for diesel particulate matter, oils, and lubricants.
• Dopant Gases: For semiconductor manufacturing.
• Steam or Air Sterilization: Autoclavable.
• Venting: Suitable for high-temperature applications.

3. Liquid

• Clarification (3.0–5.0 µm), Polishing (1.2 µm), Sterilization (0.2–0.8 µm).
• Bacteriostatic Property: Silver inhibits bacterial and microbial growth.
• HPLC Applications: Provides clearer, steadier baselines; tolerates high temperatures and aggressive solvents (e.g., THF).
