| Centrisart I ultrafiltration units. 2.5ml samples. Features a unique design, ultrafiltration in the opposite direction to the centrifugal force. This is so effective in preventing premature blockage of the filter that even whole blood samples can be deproteinized. The ultrafiltrate is collected in the floater insert tube, where it is readily accessible without removing the tube. Can be used in fixed angle or swing bucket rotors accepting 15ml conical bottom tubes. Hold up volume <5µl. Membranes: Polyethersulfone for fastest concentrations, Cellulose triacetate (CTA) for protein removal/ultrafiltrate recovery. |
