Whatman ptfe 0.45 micron filter for solvents

CYTIVA WHATMAN. Syringe Filter, 0.45 um Pore Size, PTFE Filter Material, Up to 100mL Capacity Item # 32HH77; Mfr. Model # 6784-2504

Dec 09, 2016 · Using a 90mm (or whatever diameter the membrane is) nylon or PVDF filter membrane ON top of say the 0.22 micron PES will do the dirty work and should fix this problem. Unless already pre-filtered a 0.65-0.45 micron size will do it. Just look at the drip. If it rolls through like the Wermacht thru Poland you are kind of screwed.

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.

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.

Whatman cellulose nitrate membrane filters have a low level of extractables, generally below that of other membranes of a similar type. Narrow pore size distribution - One of the major features of Whatman membrane filters is the narrow distribution of pore sizes.

Filter papers, or membranes, come in various grades depending on the application. When selecting a filter paper, determine the particle size to be retained or filtered. Assess the chemical compatibility of the membrane with the liquid or gas to be filtered.
