The enhanced ePTFE membrane offers exceptionally high gas flow rates at low pressure differentials. Fluorofil™ cartridges are recommended for sterile gas filtration and venting applications. The hydrophobic characteristics of the ePTFE membrane makes the Fluorofil™ filter cartridge particularly suitable for wet gas sterilising applications, such as fermenter air feed.
ends with a final membrane. GD/X filter construction facilitates excep-tional loading capacity with fast flow rates. This prevents the build up of back pressure typically caused by the blocking of an unprotected membrane. Features • 13 mm and 25 mm diameter
Most membrane manufacturers recommend CFVs of 5 to 35cm/s for their spiral wound membrane elements. The flat sheet membranes can be operated in this range to simulate use in such elements. Additionally, the flat sheet membranes may be operated outside of this range by users that want to examine the relationship between CVF and fouling and membrane performance in their applications.
The PTFE membrane was laminated with s great variety of fabric and paper. They are new filter media. Applied to extensive industries, including pharmacy, biochemistry, microelectronic, and lab material and etc. Directly and indirectly related to pharmacy, brewing, manufacture of pure water and special need water, beverage and dairy, chemical
PTFE is an inherently hydrophobic membrane excellent for filtration of organic-based, highly acidic or basic samples and solvents. Widely used in chromatography, it is especially well suited for the clarification of non-aqueous samples. Although this membrane is hydrophobic, it can be made hydrophilic by wetting the membrane with alcohol and then flushing with deionized water.
The sterile syringe filter provided by Aijiren has a cellulose acetate or PES filter membrane. A sterile membrane with a pore size of 0.2um is an ideal material for sterilization and filtration, while a pore size of 0.45 Ìm can be used for clarification.
Waterborne disease is hard to battle, but certainly not impossibly so. With the creation of “LifeStraw,” a customized line of water purifiers introduced by Vestergaard Frandsen, high-ranking specialists in emergency response and disease control textiles, combating waterborne infections may not be
Sterile Liquid Filtration and Bioburden Control. Sterility of liquids is critical in pharmaceutical processes and the Porvair Filtration Group range of independently validated sterilising-grade filters meet the requirements of PDA Technical Report 26 “ Sterilizing filtration of liquids ”. All filters have been bacterial challenge tested
