32 mm RephiQuik PES sterile disposable syringe filters utilize hydrophilic PES membranes, offering extraordinary combination of fast flow speeds and low protein binding. Its unique design ensures no leakage of particles to the down-stream side of the membrane. The highly asymmetric structure of PES membrane allows for high loading capacity, resulting in the high efficiency of the filter. RephiQuik PES sterile filters are ideal for biological sample preparation, such as pharmaceutical and biological aqueous solutions filtration and protein/peptide related sample filtration. Compared with usual 25 mm syringe filters, 32 mm RephiQuik filters brings at least 20% more effective filtration area (4.4 cm²) while 20% lower hold-up volume (below 80 µL).
