Product Support. Whatman PTFE membranes from Cytiva are strong hydrophobic membrane filters resistant to the corrosive solvents and aggressive media used in gas sterilization* and liquid clarification. Polypropylene grid support material for increased strength. Temperature resistant up to 120°C. Resistant to most aggressive acids, alkalis, and
Whatman Polycap TF capsule filters from Cytiva are made with durable, hydrophobic polytetrafluoroethylene (PTFE) membranes in a polyproplyene housing for use with organic solvents and chemically aggressive solutions. PTFE filter membrane is resistant to most solvents. Available in 0.1, 0.2, 0.45, and 1.0 µm pore sizes.
Whatman ® PTFE Membranes Whatman PTFE membranes are chemically stable and inert. They are suitable for applications involving aggressive organic solvents, strong acids, and alkalis. PTFE membranes are particularly suitable for preparing samples for HPLC analysis. The hydrophobic nature of the membrane also has applications for air and gas
Whatman® PTFE membrane filters PTFE membrane circles, (TE 35. Air and gas filtration use the hydrophobic characteristics of PTFE membranes and their ability to stop aqueous aerosols. Usual pore sizes are 0.2 μm and 0.5 μm. Venting of vacuum manifolds, fermentation vessels, and sterile filtrate tanks and containers utilize PTFE 0.2 μm membranes.

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. The TE range features polypropylene support material for improved strength and handling. Temperature resistant up to 120°C. Can withstand aggressive solvents, liquids
Membrane Filters, Whatman WTP (PTFE) This includes the important requirement in HPLC analysis for sample filtration where any solid particles can cause permanent damage to the column. The 0.5µm pore size is normally used.
Membrane filter Fig 2: Whatman GD/X Syringe filters contain several filtration layers that substantially reduce blockage and increase volume throughput. This is a schematic representation of Whatman GD/X features only.:KDWPDQ *' ;TM S\ULQJH ILOWHUV Whatman GD/X is excellent for difficult to filter samples that are heavily laden with particles.
Puradisc syringe filters combine premium quality and economy. They are ideal for the quick, efficient filtration of samples up to 100 mL volume. Puradisc filters are produced from pigment-free polypropylene or polycarbonate with standard inlet (female luer lock) and outlet (male luer) connections (unless otherwise stated).
Features and benefits: Pigment-free polypropylene (polycarbonate for Puradisc 30 and Aqua 30. Standard inlet and outlet luer connector. Tube-tip format (optional) for accurate dispensing into a micro-vial. Choice of membrane or glass microfiber filter media. Choice of filter sizes (4 mm, 13 mm or 30 mm) to minimize sample loss.
Whatman ReZist in-line disk filters from Cytiva are lightweight devices suitable for venting, in-line filtration, and isolation applications when working with chemically harsh solvents. Integral hydrophobic PTFE venting membrane is resistant to harsh solvents. Can be autoclaved multiple times without loss of integrity.
