SAMPLE PREPARATION DEVICE, CELL ANALYSIS DEVICE, AND FILTER MEMBER

摘要

[Problem] To provide a sample preparation device capable of generating with good efficiency a sample with a higher concentration of cells to be analyzed, a cell analysis device provided therewith, and a filter member. [Solution] The sample preparation device is provided with: a filter member having a filter for differentiating between cells to be analyzed in a sample and other cells; a first accommodation part and a second accommodation part coupled to each other via the filter; a third accommodation part capable of accommodating a sample; a communication port formed in the first accommodation part and used for allowing a sample to enter and exit the first accommodation part; a conduit in communication with the third accommodation part and the communication port; a negative pressure part for imparting a negative pressure inside the second accommodation part to thereby move the sample inside the third accommodation part to the filter via the conduit and the first accommodation part, and move components other than those to be analyzed to the second accommodation part via the filter; and a positive pressure part for imparting a positive pressure from the second accommodation part side to the filter on which cells to be analyzed are deposited.
