Description

Suited for applications involving aggressive organic solvents, strong acids, and alkalis due to being chemically stable and inert. Whatman™ WTP Range PTFE Membranes are particularly suitable for preparing samples for HPLC analysis, air and gas sterilization.

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)
