PES Syringe Filters

FILTSTAR series hydrophilic membrane with low affinity for proteins and extractable with substantially faster flow rates than PVDF syringe filter, suitable for pre-filtration and filtration of buffers and culture media.


Advantage of PES Syringe Filters

Wide range size diameter in supply
Comprehensive pore size from 0.1μm to 10μm
Ultrasonic welding ensures no contaminant to samples
100% optical integrity test

Features of PES Syringe Filters

Hydrophilic syringe filter
Very low protein binding and extractable
Wide range of chemical compatibility
Standard 1μm pre-filter for optimal performance with particulate-laden analyses
Luer lock inlet Tip make sure secure connection and avoid filter blow off

Applications of PES Syringe Filters

Purification and sterilization of aqueous solutions and/or biological samples
Protein and enzyme filtration sterilization
Filtration of Alcohol Solutions, Filtration of Aqueous Solutions, Sterile Filtration
Cell Culture
IC sample preparation and analysis
Dissolution testing
Cell culture &Tissue culture media sterilization
Don’t use with: acids, ketones, esters, halogenated or aromatic hydrocarbons.

Chemical Compatibility

Incompatible with:
Protein-based samples in aqueous solutions
Concentrated acids, chloromethane, chloroform, hexane, acetone, MEK, THF, DMSO
Ketones, esters, halogenated or aromatic hydrocarbons.

ICP-MS on metal ion extractable test of PES syringe filter(Filstar series)

Experiment object
To verify Starlab 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
Starlab Scientific Co., Ltd PES Syringe Filter(25mm 0.22) 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.
