1. PES Syringe Filters

Hawach polyethersulfone syringe filters are the hydrophilic and low affinity for proteins and extractable, which results in high throughputs when these small filter devices are used to sterilize or clarify viscous proteinaceous solutions.

The microporous membrane syringe filter made of polyethersulfone is a hydrophilic membrane with a high flow rate, low dissolution, and good strength. It does not adsorb proteins and extracts, and does not pollute the sample. Polyethersulfone (PES) syringe filter has low resistance, fast filtration speed, low protein adsorption, and is especially suitable for the filtration of viscous biological and cell tissue samples.

2. Disposable PES Syringe Filters

Hawach polyethersulfone PES syringe filters are with the membrane made from the quality manufacturers. 0.45 micron PES syringe filter housing is made of medical-grade PP plastic, the upper and lower parts are welded together by ultrasonic, with non-slip design, high-pressure resistance, and no product leakage problems.

PES syringe filters 0.22um is yellow color, and 0.45 um port size is blue. As a well-known PES syringe filter manufacturers, Hawach has the most complete varieties and sizes. A larger membrane surface area improves flow rate and throughput. PES syringe filter 0.22um membrane has the characteristics of fast and low protein adsorption. Unlike sterile polyethersulfone(PES) syringe filter, disposable 0.45 micron PES syringe filter is non-sterile.

Features of Disposable PES Syringe Filters

•Wide pH range (1-14)
•Fast and low protein adsorption
•PES syringe filter manufacturers color-coded design make easier for identification

Advantages of Disposable PES Syringe Filters

•HPLC solutions
•High throughput, low binding filter
•0.45 micron PES syringe filter units for sterile aqueous filtrations
•Sterilizing and filtering protein solutions, additives, and tissue culture media
