離心超濾裝置用于濃縮和澄清過濾生物樣品，蛋白純化，顆粒物去除，血漿或血清過濾，以及從細胞裂解液或細胞培養(yǎng)上清去除細胞或細胞碎片。Sartorius Stedim Biotech提供一系列離心設(shè)備，快速安全處理100 ?l到100ml樣品。可選拋棄型和可重復(fù)使用超濾裝置。
Overview：
· High flux PES membrane
· High retentate recovery > 90 %
· Vertical membrane design for ultra fast concentration
· Universal rotor compatibility
· Safe sample concentration due to dead-stop volume
· Convenient concentrate recovery by pipetting
· Volume graduation for easy reading/monitoring
Description
Vivaspin centrifugal concentrators are disposable ultrafiltration devices for the concentration of biological samples. Vivaspin 500 centrifugal filter units offer a simple, one step procedure for sample concentration with starting volumes up to 500 ?l. They can effectively be used in fixed angle rotors accepting 2.2 ml centrifuge tubes. The patented vertical membrane design and thin channel filtration chamber (US 5,647,990), minimises membrane fouling and provides high speed concentrations. Vivaspin 500 units are available with PES membrane in a wide range of molecular weight cut-offs. Concentrate recoveries of > 90% can be reached in less than 30 min. The dead stop pocket prevents concentration to dryness.
