water filter membrane Microporous Membrane Filter grid glossy PE NYLON

1. The nominal pore size of the membrane must be accurately selected according to the needs before use. The filtered material must be larger than the nominal pore size of the membrane (except for the particles with a pore size of 0.65, 0.8, 1.2 microns; except for bacteria with a nominal pore size of 0.22, 0.45). Micron). 2. The membrane should be cleaned before use. It should be washed with distilled water and then placed in the filter. 3. When there are many particles and bacteria in the filtrate, it should be filtered, that is, filtered with a filter medium or a large pore filter to avoid excessive blockage. 4, a lot of disinfection methods, generally using hot pressing disinfection, that is, steam sterilization at 120 ° C for 30 minutes, when hot pressure disinfection, should avoid direct steam unidirectional on the membrane, and prevent the negative pressure caused by steam condensation and the back of the film Pressure and damage. Boiling disinfection, chemical disinfection, etc. 5, sterilization and filtration is best to use the bubble method to test whether the seal is tight, whether the filter is damaged due to improper disinfection, bubble point pressure see the quality of the interim standard. 6. When filtering liquid, the filter must be wet. If the filter is dry due to disinfection, it must be wetted with sterile water. If the wetting does not affect the flow rate, all filter membranes must be applied before sterilization. Disinfection, and then in the sterile room for sterilization filtration, should be carried out in strict accordance with the sterilization protocol, using a nominal pore size of 0.22, 0.45 micron filter, E. coli using a nominal pore size of 0.65 microns. 7. The membrane is flammable and resistant to acid and alkali. It is not resistant to solvents. It is only suitable for aqueous solution (PH5-10) oil, air, juice, alcohol, etc. Before use, it must be known whether the filter material has an effect on the membrane. 8. When the filtrate is below 0.22 μm, it is not suitable to use microporous membrane filtration; for the heat source virus, it only has adsorption and cannot be completely removed. 9. When using 150 closed filter, the liquid should be put into the filter, and the original air inside should be discharged (there is a venting pipe on the upper), otherwise the filtration speed will be affected.

Φ50 water system MCE (mixed cellulose) 0.22μm/0.45μm microporous membrane

Φ50 water system MCE0.22μm/0.45μm microporous membrane

Microporous membranes include, mixed cellulose (MCE), cellulose acetate (CA), nylon (PA/NYLON), polypropylene (PP), polyethersulfone (PES), polyvinylidene fluoride ( PVDF) material, PTFE material, polycarbonate (PC film, nuclear perforated) material, glass fiber (GLASS FIBER) material. It is mainly used for sample analysis, especially filtration of mobile phase and sample in chromatographic analysis. It has a good effect on protecting the column and infusion pump piping system and injection valve from contamination. It has been widely used in gravimetric analysis, microanalysis, colloid separation and sterility experiments.
