The ultrafiltration unit is designed for volumes from 100 µl up to 15 ml. The membrane is made of regenerated cellulose, the filtrate container of copolymer styrene-butadiene (SBR), housing and screw cap of PP. The vertical twin membranes enable fast and high sample concentration and almost complete sample recovery. The pipette-friendly dead-stop reservoir eliminates the risk of centrifuging the concentrate to dryness and allows easy recovery of the highly concentrated sample. Samples up to 15 ml can be processed in swing-out rotors or 9 ml in fixed-angle rotors, which are suitable for 50 ml centrifuge tubes with a conical bottom.

• Up to 150 times sample concentration
• High chemical resistance
• Volume graduation for easy reading
