Hydrophilic PES Membranes for Scientific Study Sample Sale

Polyethersulfone(PES) membrane is made of a modified polyethersulfone polymer cast. The optimized asymmetric structure, enhanced hydrophilicity and high porosity provides extraordinary high flow rate and contaminants retention capacity. The product uniformity results in consistent filtration performance. Its high mechanical strength supports most kinds of assembling technologies.

The high asymmetric structure, as shown in figure, promises marvelous particle retention capacity and low extractables and drug&protein adsorption. The upstream surface, with larger pore size, functions as a pre-filter layer to retain big contaminants such as drug crystals and solid particles; on the other hand, the downstream surface with smaller port size plays a rold as a precise-filter layer, to retent all the rest contaminants. The gradient filtration principle and high porosity(＞75%)ensures our promised filtration efficiency. PES membrane is also availabel in positively-charged modified version, providing a solution for protein/endotoxin binding liquid filtration applications.
