Flasks are made of lightweight clear PETG with molded-in graduations. High-density polyethylene closure uses a hydrophobic 0.2 µm PTFE membrane that allows sterile air exchange. Capacities range from 125 to 2000 mL . Individually packaged for easy storage and handling.
Catalog number: CH2225-NP. Use Thermo Scientific™ Choice™ PTFE Hydrophobic Syringe Filters for filtration of aggressive organic, highly basic or hot solutions and as transducer protectors. They can filter aqueous solutions after pre-wetting with an alcohol. These syringe filters provide cleaner sample extracts by removing interfering
These hydrophobic PTFE membrane filters are laminated onto polypropylene netting for improved strength and handling. Due to broad chemical compatibility and excellent water repellency, they are ideal for solvent filtration, phase separations, venting, and air sampling. Laminated ePTFE features improved handleability, enabling convenient use in

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
The 0.5 μm pore size is normally used. Air and gas sterilization make use of the hydrophobic characteristics of PTFE membranes and their ability to stop aqueous aerosols. Usual pore sizes are 0.2 μm and 0.5 μm. Sterile venting of vacuum manifolds, fermentation vessels, and sterile filtrate tanks and containers utilize PTFE 0.2 μm membranes.
Oct 10, 2011 · Classic Filters first introduced PTFE membranes in 2002. They are most commonly used in sample systems to protect expensive and sensitive analytical equipment. Because they are hydrophobic water is repelled from the surface and pores of the membrane and cannot pass through. The newly introduced oleophobic membranes add a new dimension to the
