Description of Hawach filter membrane:
As one of the most well-known filter membrane manufacturers in China, the filter membranes produced by HAWACH are exported all over the world, which the material include: nylon, PTFE, hydrophilic PTFE, MCE, PES, cellulose acetate, PVDF, PP, and glass fiber.
The microporous filter membrane is made of polymer chemical materials and pore-forming additives applied to the support layer after special treatment.
Hawach filter membrane can be divided into:
- Roll membrane and disc membrane
- Roll filter membrane: Width of 254mm, 260mm, 270mm, 280mm, 310mm, inner core 22mm.
- Disc filter membrane: Diameters are 13mm, 25mm, 47mm, 90mm, 142mm, and 293mm.
- Pore size: 0.1μm, 0.22μm, 0.45μm, 0.65μm, 0.8μm, 1.0μm, 3.0μm, 5.0μm, 10.0μm.
- Material: nylon, PTFE, hydrophilic PTFE, MCE, PES, cellulose acetate, PVDF, PP, glass fiber.
PES Filter Membrane
Hydrophilic, for sterilization and filtration of enzymes and proteins, extraction of biological fluids, blood samples, and tissue culture, filtration and sterilization of pharmaceuticals for biological and clinical analysis.
Nylon Filter Membrane
Hydrophilic, resistant to some organic solvents, not resistant to strong acids; high protein binding capacity.
Uses: Aqueous organic mixed solution
PP(Polypropylene) Filter Membrane
Partial hydrophobicity, strong corrosion resistance, and low protein binding.
Protein recovery pre-filter and final filtration, particle chromatography low detection Level HPLC sample preparation.
Hydrophobic PTFE Filter Membrane
Resistant to organic solvents and strong acids; has low protein binding capacity;
Used for anhydrous sample filtration, corrosive solutions such as strong acid and alkali.
Hydrophilic PTFE Filter Membrane
Compared with hydrophobic PTFE, the biggest feature is that it is hydrophilic.
Highest tolerance, most recommended for aqueous organic mixed solutions.
Hydrophobic PVDF Filter Membrane
Strong tolerance, fast flow rate, low protein binding.
Protein recovery and HPLC sample preparation.
Chemical organic solution, biological solution.
Sterile MCE Gridded Membrane Filters
3.1 micron Grid;
Sterile, does not inhibit bacterial growth; high flow rate and high protein binding; obvious color contrast.
Mainly used for biological, medical, and so on.
MCE (Mixed Cellulose Ester) Filter Membrane
Hydrophilic, suitable for water-based samples;
Filtration of gas particles and bacteria;
Filtration of alcohol and particulate bacteria.
CA (Cellulose Acetate) Filter Membrane
Hydrophilic, low protein binding; limited resistance to organic solvents;
Filtration of proteins and enzymes; recovery of proteins; diagnostic cytology, biological and clinical analysis, sterilization of tissues and media.
GF (Glass Fiber) Filter Membrane
Partial hydrophobicity, coarse filter characteristics, generally used as a pre-filter material, can not filter hydrofluoric acid.
Coarse filtration processes such as pre-filtration.
Advantages of Hawach microporous filter membrane:
- The polymer membrane filter is uniform, the impurity content is low, and the impurity dissolution rate is low;
- The 100,000-class clean workshop is cut and packaged, with high cleanliness and no impurities introduced;
- ISO9001 standard specification, strict product quality control, good stability between different batches of products;
- The disc filter membrane has different diameters, and the roll filter membrane has a variety of widths for customers with different needs to choose from;
- There are many types of membrane materials, like MCE filter membrane and PVDF filter membrane, which are suitable for most laboratory samples in different solvent filtration, sterilization, and impurity removal;
- The product has many pore sizes to choose from, which is suitable for customers with different systems and different filtering purposes.
The main applications:
- A polymer membrane filter can filter out the bacteria of the particles of liquid medicine, gas, oil, beverage, alcohol, electronic instruments, etc.
- It can also be used for testing particles and bacteria.
- If you want to find a reliable filter membrane manufacturer, the filter membrane produced by HAWACH not only has high quality, and excellent price, but also provides OEM service, which will be your best choice.
