PP Membrane Filter

Description of PP Membrane Filter

Hawach PP membrane filter 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 supplier, 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; it has a series of pore sizes, high porosity, large dirt holding capacity, recoil, and high-temperature disinfection; good pressure resistance. 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.

PP 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.

Advantages of PP Membrane Filter

• PP membrane;
• ISO9001 certification available;
• Good pressure resistance;
• High-temperature sterilization
• 0.45 membrane filter has a high filtration speed;
• Hydrophobic polypropylene membrane filter, especially for liquid filtration or gas filtration;
• Passed by Gamma sterilization, autoclaving;
• Uniform membrane pores and high porosity;
• Stable chemical performance, acid, and alkali resistance;
• Stable physical and chemical properties, good compatibility;
• Superior chemical compatibility in aqueous solution and alcohol solution;
• Various sizes of pp membrane filters are in supply for different applications;
• With a series of pore sizes, high porosity, large dirt-holding capacity, recoil;
• Present a good option for membrane degassing, membrane distillation, and membrane pervaporation applications;
• OEM service is available.

Features

• Excellent heat stability;
• Superior corrosion resistance;
• Low protein binding capacity;
• 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

• Air filtration;
• Recovery of protein;
• Cell growth support;
• Gas separation and filtration;
• Polypropylene membrane is used for filtering purified water and critical aqueous solutions;
• 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, a microporous membrane filter of 0.45 μm is also used for HPLC sample preparation.

Other Advantages

The 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. 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.

Although hydrophobic, polypropylene membranes can still be used with water and aqueous solutions after wetting with alcohol (or similar water-miscible low surface tension fluid). 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, and 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.
