Hawach nylon membrane filter is aliphatic nylon, which has good hydrophilicity and resistance to the appropriate concentration of acid and base. It is suitable not only for the aqueous solution containing acid and base but also for organic solvents, such as alcohols, hydrocarbons, ethers, esters, ketones, benzene, and benzene homologs, dimethyl sulfoxide, and so on.
PTFE membranes are particularly suitable for preparing organic solvent based samples to HPLC analysis. The hydrophobic nature of the membrane also has applications for air and gas sterilization. Good resistant to most acids and alkalis make it to be the best choice for the aggressive solvent
PTFE membrane discs can be used for both aqueous and organic liquid filtration. Cobetterlab hydrophilic PTFE (polytetrafluorethylene) membrane filter has a durable wide operating temperature range and resistance to the destructive effects of many chemicals. It
Membrane Solutions supplies a wide range of vacuum filter holders, Glass Solvent Filters, Multiple Filtration Systems, and Accessories. Select from glass or stainless steel assemblies with funnels holding from 15 to 1000 ml. MS ® Vacuum filters can be steriled by autoclave.
Hydrophobic membrane filters are necessary for applications where the membrane is used to retain liquid water while allowing gases to pass through. Hydrophobic PCTE membranes typically have insufficient water entry pressures for these applications and will allow liquid water to pass at pressures lower than required.

2018/8/7 · Membrane-sample Compatibility It’s easy to overlook membrane compatibility when picking out your filter or device for your sample filtration. Good membrane-sample compatibility supports efficient filtration and minimizes resistance, while poor compatibility might result in backpressure, ineffective filtration, or even chemical attack of your membrane, leading to contamination of your filtrate.
Our STERIPleat PTFE Membrane Filter Cartridges withstand aggressive chemical filtration and are also used for sterile gas filtration. Contact Siga today. Applications Sterile process gases Venting - Fine chemicals - Solvents - Photoresists Materials Filter
Polypropylene Prefilter, hydrophobic, 5.0 µm, 47 mm. This is a 5.0 um pore size (5 micron filter) polypropylene prefilter constructed of 100% virgin polypropylene media. This filter is ideally suited for general clarifying & prefiltration applications including solvents, deionized water & bioburden reduction.
PTFE membrane filters have an excellent chemical compatibility (pH 1 to 14), so that they are also used for the filtration of solvents and acids, to which other filter types are not resistant. Moreover they can be used to filter aqueous solutions as well, but because of their hydrophobic characteristics, they must be pre-wetted with ethanol or methanol before the filtration of aqueous media

conventional filter media, these advanced membrane designs provide a significantly more porous surface area that enables good contaminant retention and increased flow rate. • High-porosity hydrophilic and hydrophobic PTFE membranes enable high flow rate
S Series (Organic Solvents) S series are installed teflon-filter (poly tetrafluoroethylene, PTFE) shows strong resistance for solvents, acids, and alkalis. It is the best for the prefiltration of the sample extracted with solvents such as chloroform, tetrahydrofuran, and so on. Ordering Information.
