Description

Description of PES Membrane Filters

Hawach PES Membrane Filters, with low extractability, high flow rate, and good strength. PES membrane provides excellent downstream cleanliness, and low protein binding for cell culture applications, such as media, sera, and growth. Low protein binding filter membrane is mainly used for sterilization filtration of biological proteins with low protein adsorption and covers pharmaceutical, water purification, food, and beverage industries.

PES membrane filter does not adsorb proteins and extracts and does not pollute the sample. Hydrophilic polyethersulfone has low protein adsorption and high drug compatibility. PES microfiltration membrane is specially designed for biochemical, inspection, pharmaceutical, and sterilization filtration devices. Hydrophobic polyethersulfone membrane is usually used with compatible non-aqueous fluids. They are also commonly used as air, gas, or ventilation filters. Hydrophobic polyethersulfone membrane filters are sometimes used with water or aqueous solutions, and in these applications, they are pre-wetted with a low surface tension water-miscible liquid before use.

PES membrane, MCE gridded membrane filter, and cellulose acetate membrane filter are all commonly used biological filters.
