Whatman® Puradisc Syringe Filters
Puradisc syringe filters combine premium quality and economy. They are ideal for the quick, efficient filtration of samples up to 100 mL volume.
Puradisc filters are produced from pigment-free polypropylene or polycarbonate with standard inlet (female luer lock) and outlet (male luer) connections (unless otherwise stated). Options include a sterile, medical-grade blister pack for critical applications and a special tube tip outlet that allows the sample to be accurately dispensed into a micro-vial, eliminating air lock.
Features and benefits:

應用
Applications (Puradisc 4)
- HPLC samples containing low solid content - filtration will improve column life
- CE (Capillary Electrophoresis) samples - filtration will eliminate spurious peaks
- Sterile filtration of low volume samples
- UV/Vis samples - filter directly into cuvette using tube tip
- Refractometry - filter samples to prevent damage to instrument optics and improve accuracy of results
- Minimizing non-specific binding to membrane (due to small membrane size)
