General description

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). These disposable filter devices are designed for use with aqueous or organic solutions containing high debris levels and for aggressive, hard-to-filter solutions. 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:
  • Pigment-free polypropylene
  • 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 microfiber filter media
  • Sterile option for critical applications
  • Wide range of membranes
  • 13 mm diameter syringe filter
  • Sample volume up to 10 mL
  • Low hold-up volume < 25 μl ensures maximum sample recovery


  • Biological sample preparation
  • HPLC sample preparation


Suitable for filtration of biological and HPLC samples.
