    • A separation device adapted for separation of a wanted end product from a sample by centrifugation. According to the invention the device comprises: a first, a second and a third compartment; a first fluid connection between the first and second compartments, arranged to be opened and closed by first closing means; a second fluid connection between the second and the third compartments, arranged to be opened and closed by second closing means. Said separation device is adapted to be subjected to centrifugation after having been filled with a first density gradient medium in the first compartment, sample in the third compartment and a second density gradient medium or sample in the second compartment, whereby after centrifugation the wanted end product will settle in the second compartment and said first fluid connection and said second fluid connection will be closed by said first closing means and said second closing means respectively.
    • 分离装置适于通过离心从样品中分离出想要的最终产物。 根据本发明,该装置包括:第一,第二和第三隔室; 第一和第二隔室之间的第一流体连接部,其布置成由第一关闭装置打开和关闭; 第二隔室和第三隔室之间的第二流体连接件,布置成通过第二关闭装置打开和关闭。 所述分离装置适于在填充第一隔室中的第一密度梯度介质,第三隔室中的样品和第二隔室中的第二密度梯度介质或样品之后进行离心分离,由此在离心之后,所需的最终产物 将沉降在第二隔室中,并且所述第一流体连接件和所述第二流体连接件将分别由所述第一关闭装置和所述第二关闭装置关闭。
