Disposable Hydrophilic PVDF Syringe Filters

Disposable Hydrophilic PVDF Syringe Filters

WINSTAR Series Polyvinylidene Difluoride ( PVDF ) is a broad purpose hydrophilic membrane which can be used in a variety of applications, no need to prewetting the filter when used with aqueous based solvent. It has high flow rates and is generally compatible with most common solvents. PVDF is a low protein binding media.



Using Germany /US imported membrane inside made in 100,000 class clean room
Ultrasonic welding ensures no contaminant to samples
Achieve more reproducible analyses


Hydrophilic syringe filter, low protein binding, high flow rate
Color-coded by membrane for easy identification
Luer lock inlet provides strong,leak-tight syringe connection to withstand filtration pressure.
Exceptional temperature stability provides extended sampling range over other membranes
Integral sealing ring provides greater strength to filter housing, leakage free and bursting free


General biological filtration, filtration of samples for high protein recovery

Chemical Compatibility

1. Compatible with: Alcohols, weak acids, proteins, peptides and other biomolecules
2. Incompatible with:
Some strong acids, bases, esters, ethers or ketones.
DMF, DMSO, MEK, acetone and most caustic solutions >6N
