Disposable PES Syringe Filters

Disposable PES Syringe Filters

WINSTAR series PES syringe filter with high through-puts when small filter devices are used to sterilize or clarify viscous proteinaceous solutions, this all because it’s low binding features. Ideal for tissue culture work and dissolution testing procedures, be recommended for Ion chromatography.



Using Germany /US imported membrane inside
Ultrasonic welding ensures no contaminant to samples
Universal Luer fitting ensure compatibly with a syringe


Hydrophilic PES syringe filter, low protein binding, fast flow rates
Color-coded design make easier for identification
Excellent flow rates and low binding coefficients
High throughput
Certified for low-level IC interference by ICP analysis
Integral sealing ring provides greater strength to filter housing, leakage free and bursting free


Purification and sterilization of aqueous solutions and/or biological samples
Protein and enzyme filtration sterilization
IC sample preparation and analysis
Filtration of buffers & culture media
Tissue culture media sterilization
Cell culture

Chemical Compatibility
