Introduction of PES Membrane Filter

Hawach Scientific brand has been well known by domestic and foreign customers, the company has the right to import and export, product sales network throughout the country, and has been exported to Europe and the United States, the Middle East, Southeast Asia, and other regions. we started to learn world-advanced production technology and experience in the very beginning. In this way, we can make sure that our quality is equivalent to Whatman’s. From now on, we have exported to more than 120 countries all over the world.

In each step of the production process, a high-quality principle is always followed to guarantee uniform pores between batches to batches. These PES membrane filters can remove particles from samples with great efficiency thanks to their uniform porosity and controlled pore sizes.

Hawach PES microfiltration membrane filter has an asymmetric structure with a high flow rate, high throughput, high strength, and high-temperature resistance. It can effectively filter out particulate matter and is suitable for use in medicine, wastewater treatment, and drinking water purification.

Hawach Scientific’s PES microfiltration membranes are hydrophilic filtration membrane, which has the characteristics of high flow rate, low solubility, and good strength. It does not absorb proteins and extracts and has no pollution to samples.

PES(Hydrophilic) Membrane Filter

A PES membrane filter is a common membrane and the world’s advanced microporous filter membrane. Most of its solutions can provide excellent performance for the purpose of retention and recovery. PES membrane filter is characterized by non-hydrophobic or hydrophilic interaction, low pollution, wide fluid range, and pH range, which is usually the preferred membrane filter in the filter process. PES hydrophilic filter membrane is made of pure polyether sulfone material, without supporting material. It has good mechanical strength, thermal stability, and wide chemical compatibility. It is suitable for pure water filtration, medium filtration, buffer fluid filtration, protein solution filtration, biological products sterilization filtration, etc.

PES microfiltration membrane (polyvinylidene fluoride), using the asymmetric structure, and uniform openings.PES has excellent heat resistance, physical and mechanical properties, insulation properties, etc. PES microfiltration membrane can ensure low protein adsorption and low dissolution in the filtration process. Hawach Scientific company specializes in the production of PES filter membranes, stable quality, products exported to Europe, North America, and other countries. We have more than 16 years of experience in the filtration industry.
