Torit-Tex® is a proprietary expanded PTFE (Polytetrafluroethylene) membrane, manufactured solely by Donaldson. When applied to a baghouse filter, it increases temperature resistance, reduces chemical degradation and repels water. Torit-Tex enhances

Syringe filters are single-use, membrane-based devices used for the removal of particulate impurities from liquid and gas samples prior to analysis by methods such as HPLC, ion chromatography, gas chromatography, ICP, and dissolution testing. Proper filtration of samples improves the quality and consistency of analytical results and decreases

15/7/2013 · 8. Conclusions. Among the various membrane separation processes that are used for the radioactive decontamination of water, the pressure driven processes, including reverse osmosis (RO), nano-filtration (NF), ultra-filtration (UF) and micro-filtration (MF), have already proven themselves as the most versatile methods.

In this blog we explore properties and uses of common qualitative filter paper grades such as 1-6, 595, 597, 598, and 602. Filter paper. We all use it at one time or another. Whether we’re testing soil samples, removing dissolved gases from beer, or perhaps just

It’s clear that PTFE is a very useful, unique product, but in order to establish the winner between Teflon vs PTFE, we need also to consider what Teflon is too. Discovered in 1938, Teflon was developed by the DuPont Co and managed by a spin-off of the company known as Chemours.

The PT N filter element meets the guideline for Food Contact Use as given in European Regulation (EC) Number 1935/2004. All polymeric components (polypropylene, PTFE) meet the requirements of EU Directive EC/10/2011

One of the most common misconceptions about air filtration is that an efficient, sterilizing-grade, hydrophobic filter must have a pore size of 0.2 µm. This belief is incorrect because due to the nature of gas filtration through microporous membrane media, particles smaller than the pore size, usually on the order of 10-1, are retained in venting applications.

Filter Membranes. Zitex is a chemically inert, thermally stable, porous PTFE membrane. Available in standard grades having pore sizes in the approximate range of 1 - 6 microns, Zitex can be used as a self-supporting membrane in a wide variety of particle filtration applications in aggressive environments.

Stock Standard Solution (20 mg/L): Prepare from commercially available standards (solid or liquid form) in 10 mL volumetric flask, 5 Filter the supernatant into HPLC vial through a 0.2 µm PTFE Membrane filter. [Note: Protect sample solutions from light.] 2.4 ...

Choose a filter or membrane based on: 1) Chemical compatibility of the membrane and housing with your sample matrix. 2) Size and amount of particulates in the sample. 3) Potential interactions (binding) between the membrane and sample components. 4) Special considerations such as requirement for prefilter or inorganic ion certification.
