Pall filter areas involved in a wide Pall filter cartridge has a pivotal role in the industry. So what is the filter it? Yongqing Hangda introduce you http://www.hangdalvye.com: 1, hydrophilic hydrophobic filter Category: Polypropylene, PTFE filter material is hydrophobic, polyether sulfone filter material is hydrophilic. 2, the filter substrate can be divided into hydrophilic and hydrophobic, the bubble point values ??do preinvasive former water infiltration when polyethersulfone generally requires 30 minutes in cold water, hot water takes 15 minutes (cooling test) . And hydrophobic with 95% ethanol or 60% isopropanol infiltration. 3, the filter sterilization method (1) Removing the filter, placed in sterile cabinet, at 121oC, 25 minutes sterilization. (2) Online pure steam sterilization 115 oC for 1 hour. 4, out of the flow identification filter out into the middle of the positive and negative impulse may be different direction. 5, Aperture identify hot melt font cartridge casing, indicating the filter material and pore size. 6, the filter installation method (1) the O-rings moist and slowly insert the cartridge vertically, must all be plugged into stainless steel circular tank. (2) The portion of the filter press with stainless steel plates fins well plate without too tight, to prevent the variation of the high temperature sterilization filter. (3) avoid direct hand contact with the filter. (4) Before using as first with 2% sodium hydroxide soak, then rinse. 7, the storage method (1) immersed in the disinfectant cartridge 75% ethanol; (2) filter out the drying, (50oC 36 hours); (3) Please do not dry the filter in a plastic bag to prevent mildew package. (4) After the polyether sulfone filter material use, "Do not put lye in" (in their own hands the data do not match), placed in 75% ethanol or 60 degrees Celsius dry storage. Pulsating vacuum sterilizer manufacturers disagree recommended 121 degrees Celsius .30-minute steam sterilization. (But often do not recommend sterilization, affect the use of life) text keyword: Pall filter
