Our Etchclean PES membrane is a mechanically strong membrane and is resistive to a broad range of aqueous solvents. The Etchclean filter is the filter of choice for DHF and BOE cleaning applications with very low metal ion extractables , as low as 20 ppb in total where the od83mm/10” sample was soaked in 5%, 1500ml HCl for 24 hrs.
Membrane Solutions offers full membrane filter for various solvents or liquid or gas, including PES , MCE, Nylon, PVDF , PTFE , PP , CA, Nylon Mesh and PC, the disc diameter is from 13mm to 293mm, which are manufactured in ISO 9001 certified facility. Most membranes can be sterilized if needed.
For example, Membrane Technology and Research, Inc. (USA) recently reported on the performance of a cellulose ester-based membrane custom manufactured for them 93. The structure of one type of cellulose, carboxymethyl cellulose (CMC), is shown in Figure 4B .
PTFE and other hydrophobic materials are well suited to organic samples and solvents, which result in no resistance or back pressure. However, some organic solvents can absorb into the membrane material, especially when in contact for long periods.

2012/8/13 · PTFE as a Membrane for Syringe Filters is considered to be more “chemically resistant” and Nylon to be the most “extractable free” for HPLC or Dissolution Testing. The simple explanation of the differences is that Chemical Resistance is defined as the durability of the membrane to withstand some harsh Solvents (normally not used in HPLC or dissolution testing).
Filter both aqueous and organic solvents Optically clear when wet Hydrophilic PTFE membranes are a thin, unsupported, highly porous film that offers maximum chemical and pH resistance to a broad range of aqueous and organic solvents. This membrane exhibits high flow rates with minimal

AcroPrep Advance 0.2 and 0.45 µm GHP Membrane Filter Plates. 2 hrs. This solvent retention table shows results reported for 200 μL/well (350 μL plates) and 300 μL/well (1 mL plates) of liquid with 30 min., 2 hr. and 24 hr. incubations at room temperature without a humid chamber. n = 24 (wells/solution).
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
Filtration Membrane Materials and Applications Filtration membranes may be composed of nylon, polypropylene, cellulose, nitrocellulose, glass fiber, and PTFE. Nylon filtration membranes are chemically compatible with a wide range of solvents. Polypropylene filtration membranes are used with more aggressive solvents.
Hydrophobic PTFE. These filters are highly porous, thin, and they behave as absolute retentive membranes. They remain inert even with strong bases, strong acids, and solvents which are chemically aggressive. You can use these membrane filters for sterilizing gases, venting gas and air, or for clarifying and sterilizing strong acids or solvents
