Whatman® Puradisc AQUA 30 Syringe Filter, cellulose acetate, 0.45 μm

Specifically designed for filtration of environmental samples prior to COD and DOC analysis. The membranes used in these devices are prewashed prior to assembly so as to reduce the organic carbon level.

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.
