Pura Disc 13mm GMF Syringe Filters, 0.45um, 500 Pk SKU: 6818-1304

Whatman 13 mm Puradisc Filters are produced from pigment-free polypropylene with standard inlet (female luer lock) and outlet (male luer) connections. 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.

This Puradisc 13 syringe filter combines premium quality with economic efficiency. They are well suited for rapid, routine syringe filtration of samples Up to 10 ml. Puradisc syringe filters cater to a wide variety of sample types and applications, including capillary electrophoresis, biological preparations, protein filtration, and UV spectroscopy sample preparation. Different Puradisc membrane media support diverse chemical solvents and compounds.

This model has a 0.40.45 µm pore glass microfiber membrane that is hydrophilic and has excellent compatibility with organic solvents and strong acids (except hydrofluoric acid) and bases. However, it is not a micropore membrane and so has a slightly less exact retention efficiency than polymeric membranes. GMF can also contribute extractables that interfere with ionic and metals analysis.
