Imported nylon 66 (Nylon66)
Characteristic:
The membrane imported from the UK originated from the British Membrane Company in 1948.
It has better performance than domestic nylon 6, good hydrophilicity, high strength, high flow rate, high porosity, suitable for most organic solvents and aqueous solutions, high throughput, high quality resistance, high temperature resistance, acidic aqueous solutions and organic solvents. The membrane material has high surface quality, wide drug compatibility, wide range of uses, low dissolution rate, and stable chemical properties.
Applications:
Liquid clarification, sterilizing filtration and particulate filtration
Can be sterilized by high temperature, high pressure or ethylene oxide
Imported polyethersulfone (PES)
Characteristic:
German imported membrane, originated from German membrane company in 1965.
Hydrophilic membranes have high chemical and thermal stability, high mechanical strength, large flux, and high flow rate. Currently, the filter membrane with the highest flow rate is polyethersulfone. The membrane with the lowest protein binding capacity can improve protein recovery due to its low protein adsorption. It is the best choice for ion chromatography. It has wide medicinal compatibility and the lowest dissolution rate.
Application:
Filtration of organisms and serum in the pharmaceutical industry, terminal filtration of antibiotics, etc. Terminal filtration of beverages, wine, etc. in the food industry, terminal filtration of ultrapure water
Can be sterilized by high temperature, high pressure or ethylene oxide.
Polytetrafluoroethylene (PTFE)
Characteristic:
Imported membranes from the United States originated from the American Membrane Company in 1915.
After being treated with ethanol or isopropyl alcohol, it becomes a hydrophilic film and can be naturally moistened. It is resistant to high temperatures, strong acids, strong alkali, organic solvents and oxidants. It has good chemical compatibility and can withstand most chemical solvents.
Application:
For sterilization and filtration of water solvents
Gas sterilization filtration and vacuum filtration
High purity gas filtration for electronic industry
Steam filtration
Sterile exhaust filtration of fermentation tanks, storage tanks, and ingredient tanks in the food industry
Mixed cellulose (MCE)
characteristic:
The membrane material has a smooth surface, light and thin texture, high porosity, good interception effect, good hydrophilicity, large water flux, uniform microporous structure and extremely low adsorption rate. It is not resistant to organic solutions and strong acid and alkali solutions. It is only suitable for aqueous agents. Filtration of drugs or other water solvents, cost-effective.
application:
Sterilization and particle removal in laboratories and small production processes, sterilization and filtration of culture media and culture fluids, and determination of bacterial flora in water bodies
Polypropylene(pp)
characteristic:
Depth filtration, stable physical and chemical properties, good compatibility, high porosity, large dirt holding capacity, capable of backwashing and high temperature sterilization, and good pressure resistance
Application:
Pre-filtration of biomacromolecule precipitates before filtration membrane
Nylon 6 (Nylon6)
Characteristic:
It has good hydrophilicity, high flow rate and low resistance, extremely low extractables, excellent mechanical strength (PET support layer), and particle retention rate of 99.99%.
Application:
Pre-filtration, sterilizing filtration and solid-phase extraction technology of sample mobile phase - liquid chromatography detection application membrane; removal of bacteria, microorganisms and impurities in the food and beverage industry; removal of suspended solids and colloids in the water treatment industry.
Sterilization method:
Sterilizable with gamma rays and ethylene oxide
Polyvinylidene fluoride (PVDF)
Characteristic:
After being treated with ethanol or isopropyl alcohol, it becomes a hydrophilic membrane with extremely low protein adsorption rate. Resistant to chemical corrosion and oxidation.
Application:
Western and Southern transfer and protein sequencing
Sterilization and filtration of liquids such as protein solutions, tissue culture media, antibiotics, etc.
Solvents such as acids, alcohols, alkanes, aromatic hydrocarbons, and halogenated hydrocarbons remove particles
Purification of suspended micro-sites in the air and air sterilization in the fermentation industry
Purification of insoluble matter in oils and gravimetric analysis of solid particles
Biotest TCA Precipitation
Can be sterilized by high temperature, high pressure or ethylene oxide
