Filtry membranowe z PTFE - typu WTP
Membrany z PTFE są wytrzymałymi, hydrofobowymi filtrami membranowymi, odpornymi na działanie rozpuszczalników i agresywnych mediów stosowanych w sterylizacji gazów i klarowaniu cieczy.
Whatman™ PTFE membranes 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 solvents
• Hydrophobic membrane filters can collect aqueous aerosols

PTFE membranes are especially effective for use with aggressive solvents, liquids, and gases. Browse the Whatman™ range of PTFE filters to find the right membrane for your applications.

Gas sterilization* and liquid clarification
PTFE membranes are used for liquid clarification of corrosives, solvents, and aggressive fluids. Effective sample filtration is critical to prevent equipment damage. Whatman™ PTFE hydrophobic membrane filters are also suitable for air and gas sterilization* because of their ability to capture aqueous aerosols.
