Centrifugal Filters

Pall’s centrifugal filter devices can accelerate sample processing, maximize sample recovery, add versatility and prevent solution bypass.

Accelerate sample processing – Concentrate and purify samples with starting volumes of < 50 µL to 60 mL.

Maximize sample recovery – Obtain high flow rates and low non-specific protein and nucleic acid binding.

Add versatility – Available in various membrane types; Nanosep®, Microsep®, Macrosep™, and Jumbosep™ devices are available with Omega™ (modified polyethersulfone) ultrafiltration membrane in a variety of MWCOs. Nanosep MF devices are available with low-binding Bio-Inert® (modified nylon) and wwPTFE (hydrophilic polytetrafluoroethylene) membranes. Microsep and Macrosep devices also are available with Supor® (polyethersulfone) membrane.

Prevent solution bypass – Membrane seals stop solution leakage, minimizing sample loss.

Easy visual identification – Devices are color-coded for a wide variety of membranes, ranging from 1k to 0.45 µm
