離心超濾裝置用于濃縮和澄清過(guò)濾生物樣品，蛋白純化，顆粒物去除，血漿或血清過(guò)濾，以及從細(xì)胞裂解液或細(xì)胞培養(yǎng)上清去除細(xì)胞或細(xì)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?？蛇x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 conceation · Universal rotor compatibility · Safe sample conceation due to dead-stop volume · Convenient conceate recovery by pipetting · Volume graduation for easy reg/monitoring Description Vivaspin ceifugal conceators are disable ultrafiltration devices for the conceation of biological samples. Vivaspin 500 ceifugal filter units offer a simple, one step procedure for sample conceation with starting volumes up to 500 ?l. They can effectively be used in fixed angle rotors accepting 2.2 ml ceifuge tubes. The patented vertical membrane design and thin channel filtration chamber (US 5,647,990), minimises membrane fouling and provides high speed conceations. Vivaspin 500 units are ailable with PES membrane in a wide range of molecular weight cut-offs. Conceate recoveries of > 90% can be reached in less than 30 min. The dead stop pocket prevents conceation to dryness.
