Chemical Compatibility. PES membranes were exposed to the following chemicals for 48 hours. If there was no significant change in the bubble point, strength or appearance of the membrane, it was judged compatible with the chemical. If the membrane dissolved, or otherwise lost its strength, or changed significantly in appearance, it was rated
The main application of these membrane filters ist the filtration of air, gases and chemicals. 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.
Millipore ® polypropylene membranes and net filters feature both solvent-compatibility and thermal stability. Constructed from pristine polypropylene material, these filters are ideally suited for general solution clarification and prefiltration applications, including bioburden reduction.
The PTFE (polytertrafluoroethylene) membrane is a hydrophobic membrane with broad chemical compatibility, and excellent particle retention AcroPrep Plates eliminate crosstalk between wells. Membranes are individually sealed in each well with a proprietary
PTFE filter membrane, 47 mm diameter, 0.45 µm pore size, 100/pk 5191-4336 PTFE filter membrane, 47 mm diameter, 0.20 µm pore size, 100/pk 5191-4339 Nylon (polyamide) • Hydrophilic membrane suitable for particle removement of alkaline solutions and
Membrane Type (PTFE, GHP, PVDF, Nylon) — Typically, the first step in selecting a suitable filter is to choose a membrane that is chemically compatible with the sample (see chart opposite). For aqueous samples, it is preferable to use a hydrophilic membrane (GHP, PVDF or Nylon) versus a hydrophobic membrane (PTFE).
7/8/2018 · 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.

1) Syringe filter housings are manufactured from solvent-resistant, low-extractable polypropylene resins specifically selected for wide compatibility with common HPLC sample matrices. 2) Solutions at temperatures up to 100°C can be filtered using syringe filters. 3) Syringe filters can be sterilized by autoclave at 125°C for 15 minutes.
0.2 µm, AcroPak 300 Vent Filter Capsule with PTFE Membrane Offers broad chemical compatibility with PTFE membrane and polypropylene housing; 100% integrity-tested to provide the high level of confidence you require “Pall Laboratory products are designed for laboratory applications only.
compatibility with the liquid you want to filter by performing a trial filtration run before you start your actual filtration. Legend Compatible ++ Limited compatibility + Not compatible - not analyized n.a. 1) gamma irradiation feasible for Minisart ® Air For Minisart
The hydrophobic characteristics of the ePTFE membrane makes the Fluorofil filter cartridge particularly suitable for wet gas sterilising applications, such as fermenter air feed. For solvent and aggressive chemical filtration applications, Fluorofil™ cartridges offer a wide range of chemical compatibility with high thermal stability.
2/8/2021 · 1.6 Polytetrafluoroethylene filter membrane (PTFE) ·Features Hydrophobicity, wide chemical compatibility, good temperature resistance, strong acid and alkali resistance, chemically corrosive solvents and oxidants ·Application 1) In chemical, pharmaceutical
Chemical compatibility is a critical consideration when selecting the proper sample prep syringe filter for your application. This chart outlines the chemical compatibility of the most common syringe filters. The contact time was 24 hours at 20 C. Syringe Filter
Where no polymer-solvent specific information was available, general compatibility with a solvent type was stated; e.g., PES is compatible with alcohols LTD = Limited Recommendation. Chosen for those polymer-solvent combinations that showed both top and less-than-top ratings in published compatibility tables where exposure times of less than 24 hours at room temperature are recommended.
