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.
Features of 0.22 Micron, 0.45 Micron Polyethersulfone Syringe Filters
Advantages of 0.22 Micron, 0.45 Micron Polyethersulfone Syringe Filters
•Human hands never touch the filter during assembly
•100% integrity tested, individually packaged, and sterilized
•Manufactured in a controlled environment using an automated process
Applications of 0.22 Micron, 0.45 Micron Polyethersulfone Syringe Filters
•Sample preparation of aqueous solutions
•Sterilize biological fluids, serum or tissue culture media additives
•Filter probe and hybridization solutions to reduce backgrounds
ICP-MS on metal ion extractable test
Experiment object
To verify Hawach Scientific Co., Ltd PES syringe filter can use in ICP-MS on metal ion test field, and quantitative test the amount of extractable ion. Experiment process
Hawach Scientific Co., Ltd 0.22 micron PES syringe filter(25mm) is filtered by 3ml ultra-pure water, the first 1ml discard, collect the first 2ml filter water and go on tested by ICP-MS of several ion species. Each sample was repeated for 3 times. Experiment result
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

The sterile polyethersulfone(PES) syringe filter is a fast, convenient, and reliable filter tool that is routinely used in laboratories. PES syringe filter has a beautiful appearance, lightweight, and high cleanliness.
Features of Hydrophilic sterile PES syringe filter
•Hydrophilic sterile PES syringe filter
•Polyethersulfone(PES) syringe filter have fast flow rates
•Very low protein binding and extractable
•PES syringe filter have broad chemical compatibility
•Same as Nylon Syringe Filters, both have standard 1um pre-filter (Glass fiber or PP) for optimal performance with particulate-laden analyses
Applications of Hydrophilic sterile PES syringe filter
•0.45 um PES syringe filter is ideal for HPLC solutions
•The filtration of biological and serum in the pharmaceutical industry, the terminal filtration of antibiotics in large infusions
•Rapid sterile filtration of tissue culture media, additives, buffers and other aqueous solutions.
