Description & Specifications

Specifications

Material Polytetrafluoroethylene (PTFE)
Wettability Hydrophobic
Membrane Type WTP

PTFE stretched film, laminated to a nonwoven polypropylene support web>

  • Naturally hydrophobic
  • 0.5μm size is generally used for sample prefiltering in HPLC analyses for sample filtration where any solid particles can cause permanent damage to column
  • 0.2μm size is used in sterile venting of vacuum manifolds and sterile filtrate tanks and containers

 

Use up to 120°C (248°F); higher temperatures will cause laminate to soften.

Applications:

 

  • Clarification of corrosives, solvents, and aggressive fluids
  • Collecting moist dusts for subsequent analysis (0.5 and 1.0μm pore sizes)
  • Air and gas sterilization (0.2 and 0.5μm pore sizes)
