Description of PES Filter Membrane:
Hawach includes disc and rolls PES filter membranes, which have the characteristics of high flow rate, low extractable, has natural hydrophilic properties. Compared with other membranes, the PES filter membrane has very good water wettability, so the PES filter membrane has an extremely high tax flux.
Advantages of Hawach PES filter membrane:
- HAWACH supplies disc and roll PES filter membranes
- Disc: 13mm, 25mm, 47mm, 50mm, 60mm, 90mm, 100mm, 106mm, 142mm, 150mm, 200mm, 250mm.
Pore size: 0.1μm, 0.22μm, 0.45μm, 0.65μm, 0.8μm, 1.2μm.
Roll: Width: 254mm
Pore size: 0.1μm, 0.22μm, 0.45μm, 0.65μm, 1.2μm. - All sizes. like 0.22 um polyethersulfone membrane filter sterile with very low protein adsorption capacity, widely used in filtration and clarification in food, medical and other fields.
- The hydrophilic polyethersulfone membrane filter has the characteristics of a high flow rate, low extractability, low protein adsorption, good mechanical strength, excellent heat resistance, and chemical resistance.
Features of hydrophilic polyethersulfone membrane filter:
- It has good heat resistance and processing performance and is resistant to chemicals. Except for concentrated sulfuric acid, concentrated nitric acid, and strong polar solvents, it is not attacked by general chemical reagents.
- All sizes. like 0.22 um polyethersulfone membrane filter sterile can be used to filter high-temperature liquids
- Hydrophilic membrane with high chemical and thermal stability
- Strong acid and alkali resistance (pH range 1-14) and high mechanical strength.
- Large flux, high flow rate, currently the highest membrane speed is polyethersulfone
- Membrane with the lowest protein binding, resulting in improved protein recovery due to low protein adsorption
- Has broad pharmaceutical compatibility
- Lowest dissolution rate
- Superior flow rates, faster flow rates than PTFE membrane and PVDF membrane
- Long service life
- Broad chemical compatibility
- Biosecurity
Application:
- Biological vaccines, plasma, serum filtration
- Sterile filtration of buffer and culture solution
- Large infusion (LVP) sterile filtration
- Eye drops sterile filtration
- Aqueous antibiotic liquid filtration
- Pharmaceutical and sterilization filter devices and other fields.
- Suitable for filtration of aqueous samples, proteins, acids, alcohols, and aliphatic hydrocarbons
