As we all know, polyethersulfone filter membrane (PES membrane) is made of polyethersulfone microfiber hot-melt bonding. It is a membrane material for depth filtration and often for various tests. Here is a brief introduction:
What is the pes filter membrane:
- The hydrophilic PES filter membrane is made of unsupported pure polyethersulfone, which has good mechanical strength, thermal stability, and broad chemical compatibility.
- It is suitable for sterile filtration of biological products such as pure water filtration, medium filtration, buffer filtration, fermentation broth filtration, etc.
Features of pes filter membranes:
- A variety of apertures with low biosorption and high flow rates
- It has excellent high-temperature resistance and broad chemical compatibility.
- Low protein adsorption ensures maximum recovery of the active ingredient of interest.
- And the membrane filter has a gradient pore structure and can be for as a pre-filter. The filter element has a large flow rate, small pressure difference, and long service life.
- And with a high separation process, which is a passive transfer process. Fluid passes through the membrane under the action of a pressure gradient.
- Actually, separated the particulate impurities quickly and often in fluids by the following four modes of action, namely sieving, bridging, adsorption, and ion attraction.
- It has the characteristics of a high flow rate, low extractability, and good strength. Does not adsorb proteins, and does not extract and contaminate samples.
- In addition, produced by a unique process, it has a super-asymmetric membrane pore structure and has a higher water flux than other membranes under the same pore size.
- The low protein adsorption properties of PES membranes make them ideal for biological sample preparation.
- And with high strength, high flow rate, low extractable, low protein adsorption
Applications:
- Low protein adsorption and high drug compatibility, specially designed for biochemical, testing, pharmaceutical, and sterile filtration equipment.
- Used for routine filtration sterilization, filtration intravenous, biopharmaceutical bacteria isolation
- For sterilization and filtration of enzymes and proteins
- And for biological fluid blood sample extraction and tissue culture
- Biological and clinical analysis of drug filtration and sterilization
- PES membrane has extremely low protein adsorption capacity and is widely for filtration and clarification in food, medicine, and other fields.
Some problems about using pes filter membrane:
- Is the polyethersulfone filter membrane head organic or water-based?
- The polyethersulfone filter membrane head is organic.
- And polyethersulfone resin (PES) is a thermoplastic polymer material with excellent comprehensive properties developed in 1972. It is one of the few special engineering plastics at present.
- With excellent heat resistance, high mechanical properties and insulation properties, etc.
- And especially has outstanding advantages such as continuous use at high temperatures and stable performance in environments with rapid temperature changes, and has been widely used in many fields.
- Polyethersulfone (PES) microporous membranes are naturally hydrophilic. Different from other membrane varieties, the PES membrane with excellent water wettability, so the PES membrane is good in higher water flux.
- Is the pes membrane an organic phase or an aqueous phase?
- The aqueous phase, but can also tolerate some organic solvents, such as ethanol, etc.
- The purpose and use of the ion chromatography pes filter head?
- It is placed at the tip of the syringe to allow the sample to pass through the filter membrane.
- And the main function is to purify the sample and protect the chromatographic column and mainly to filter and protect the loss of the column to prevent pollution
