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.

• Eight different material options
• Choice of 4, 13 and 30 mm syringe filter diameter to suit sample volume
• Range of pore sizes for retaining a variety of particles
• Optional sterile, medical-grade blister pack
• Optional tube-tip format for accurate dispensing into a micro-vial
• Recyclable after use

Puradisc™ 13 filters have a 13 mm diameter and hold a sample volume of up to 10 mL. They have a low hold-up volume of less than 25 µL, which ensures maximum sample recovery.
