Descrizione generale

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:

• Pigment-free polypropylene (polycarbonate for Puradisc 30 and Aqua 30
• Standard inlet and outlet luer connector
• 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
• Choice of filter sizes (4 mm, 13 mm or 30 mm) to minimize sample loss
• Sterile option for critical applications
• Wide range of membranes
