General description

All 25mm diam have changed to 33 mm diam to provide better coverage.

Units contain Durapore Hydrophilic PVDF filter membranes in plastic housings with Luer lock inlet and Luer slip outlet fittings.

Units smaller than 25 mm diameter are specifically designed to minimize hold-up in filtration of small volumes. The 3-4 mm units are recommended for volumes of <1 mL; the 13 mm units are recommended for volumes of 0.5 - 10 mL.


Suitable for filtration of biological samples.
