Microporous membrane filter 0.45 μm is made of polypropylene ultrafine fibers by hot melt bonding, which is a kind of membrane material for deep filtration. As a polypropylene membrane filter suppliers, the pp membrane is made of food-grade isotactic polypropylene, without any additives in the whole production process.
PP membrane filters (Polypropylene) are hydrophobic membranes, which are resistant to a wide range of organic solvents with excellent chemical stability and compatibility (apart from hydrofluoric acid and bases). Polypropylene membrane filter has stable physical and chemical properties and good compatibility; polypropylene membrane filter has a series of pore sizes, high porosity, large dirt holding capacity, recoil, and high-temperature disinfection; good pressure resistance.
The polypropylene membrane filter is flexible and durable, not easy to break, non-toxic, and uniform in strength. Even if you wear gloves or use tweezers and other tools to clamp the membrane, it will not cause damage, tearing, or bending.
Excellent chemical resistance, acid, alkali, and solvent resistance, including polar solvents. High temperature resistance and can be sterilized by pressure steam. It can be used at high temperatures and can ensure a good flow rate and flux for users.
Polypropylene membrane filter is widely used as the most economical membrane filter. 0.45 membrane filter can also be used for pre-filter for samples with a high filtration speed. Although hydrophobic, polypropylene membrane can still be used with water and aqueous solutions after wetted with alcohol (or similar water-miscible low surface tension fluid).
Polypropylene membrane filter has no media shedding and no possibility of re-contamination. It is very suitable for cell growth supports, media filtration, and disinfection of tissue culture media, pharmaceuticals, and other solutions for biological research.
PP membrane is suitable for organic solvents, and is very suitable for HPLC mobile phase filtration and degassing especially acetonitrile. 0.45 membrane filter has a long service life, is suitable for position difference filtration, high-viscosity, multi-suspended matter sample filtration, and the filtration accuracy is stable and reliable. PP membrane can also be used in the field of gas filtration.

Features of 0.45 Membrane Filter
Excellent heat stability Low protein binding capacity Superior corrosion resistance Strongly corrosive organic solvent filtration Hydrophobic filter membrane but can be used in water and aqueous solutions if wetted PP filter membrane has good strength, no deformation, no media shedding, and no re-pollution 0.45 membrane filter is temperature resistant and can be autoclaved at 121°C for 30 minutes, and the working temperature is below 100°C Used after being soaked in 70% ethanol for a few minutes before use Excellent chemical resistance. It is resistant to acids, alkalis, and solvents, including polar solvents (except benzene, xylene, etc.)
Applications of Membrane Filter 0.45 μm
Air filtration Recovery of protein Cell growth support Gas separation and filtration Polypropylene membrane is used for filtering purified water and critical aqueous solutions The polypropylene membrane filter is used for photoresist production HPLC mobile phase filtration and degassing Biology, medical solution, tissue culture medium sterilization 0.45 membrane filter is ideally suitable for filtration of compatible high-purity nonaqueous liquids PP filter membrane is made of polymer materials, non-toxic, and can be widely used in medicine, the chemical industry, food, beverage, and other fields. Same as nylon membrane filters, microporous membrane filter 0.45 μm is also used for HPLC sample preparation.
