Hawach FILTSTAR series PES 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.
Low protein adsorption and high drug compatibility, specially designed for biochemical, inspection, pharmaceutical, and sterilization filtration devices.

Applications of 0.22 Micron PES Syringe Filters
•Sample preparation of protein-based
•High throughput, low binding filter
•Units for sterile aqueous filtrations
•Sample preparation of aqueous solutions
•Filter probe and hybridization solutions to reduce backgrounds
bull;Sterilize biological fluids, serum or tissue culture media additives
•High throughputs when sterilizing or clarifying even the most viscous proteinaceous solutions
•Difference from active carbon syringe filter used in gas filtration, PES syringe filters are ideal for liquid filtration.
ICP-MS on metal ion extractable test of PES syringe filter
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
