Puradisc Syringe Filters combine premium quality and economy. They are well suited for quick, efficient filtration of samples up to 100mL 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.
  • Standard inlet and outlet luer connectors.
  • Optional sterile, medical-grade blister pack.
  • Tube-tip format (optional) for accurate dispensing into a micro-vial.
  • Choice of membrane or glass microfibre filter media.
  • Choice of filter sizes (4mm, 13mm, or 30mm) to minimise sample loss.
  • Sterile option for critical applications.
