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 sterilization. The membrane is laminated onto a nonwoven polypropylene support web for improved strength and handling and can be used at temperatures up to 120ºC. Chemically stable and inert: PTFE is the membrane of choice for use with aggressive solvents, liquids, and gases that can attack other membranes. It is resistant to most acids, alkalis, and solvents. Applications: 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 p See full list on sigmaaldrich.com Applications: 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 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.

These 25 mm syringe filters offer an available prefiltration layer and wide choice of filter media.Syringe filters are attached to the end of a syringe to remove particles from a sample prior to analysis. Filtering liquids, the single-use devices force liquids through the filter either when fluids are initially drawn or delivered. Circular shaped in diameters that fit common syringe sizes, the
Feb 17, 2020 · A syringe filter (sometimes called a wheel filter for its wheel-like shape) is a single-use membrane based filter cartridge, to be attached with a syringe to remove impurities in liquid solutions. This pre-filtration step is vital in preventing damage to instruments (e.g. liquid chromatography, ICP, etc.).
SiliCycle Syringe Filter Polytetrafluoroethylene (PTFE) Hydrophobic polytetrafluoroethylene syringe filter is an excellent media for filtration of strong acids and aggressive organic solvents. Wetting the membrane with alcohol and water gives a hydrophilic characteristic.
SKC developed a 25 mm conductive polypropylene cassette with 1.0 µm PTFE filter and polypropylene support pad to minimize wall losses and permit in-situ extraction for enhanced recovery of lactic acid at nanogram levels. See PTFE Filter 225-1725. Sampling for Metalworking Fluids (NIOSH 5524): See full list on skcltd.com
In other words, the amount of volume you plan to push through the filter. As a general rule, use a syringe filter with a greater membrane area if you plan to push a high volume of aqueous solution through it. Syringe filters for aqueous solutions are available in diameters of: 4mm, 13mm, 17mm, 20mm, 25mm, 30mm, and 33mm.
Polypropylene, nylon, and PTFE membranes are ideal for sample preparation and small volume chemical filtration.Syringe filters are attached to the end of a syringe to remove particles from a sample prior to analysis.
