Description

General description

Whatman PTFE membrane filters from Cytiva′s business are chemically stable and inert, making them suitable for use with aggressive organic solvents, strong acids, and alkalis.

High chemical resistance and mechanical strength

One of the major applications for the PTFE membrane is the clarification of corrosives, solvents, and aggressive fluids. This includes the important requirement in HPLC analysis for sample filtration where any solid particles can cause permanent damage to the column. The 0.5 µm pore size is normally used. Air and gas sterilization make use of the hydrophobic characteristics of PTFE membrane filters and their ability to stop aqueous aerosols. Pore sizes of 0.2 µm and 0.5 µm are typically used. Sterile* venting of vacuum manifolds, fermentation vessels, and filtrate tanks and containers utilize PTFE 0.2 µm membranes.

Application

• Clarification of corrosives, solvents, and aggressive fluids
• HPLC

Features and Benefits

• The TE range features polypropylene support material for improved strength and handling
• Temperature resistant up to 120°C
• Can withstand aggressive solvents, liquids, and gases that damage other membranes
