Abstract
A sample preparation device includes: a filter member including a filter configured to separate cells being an analysis target from other components in a sample; a first receptacle and a second receptacle configured to be connected to each other via the filter; a third receptacle capable of holding the sample therein; a negative pressure section configured to apply a negative pressure into the second receptacle, thereby to move the sample in the third receptacle toward the filter via the first receptacle, and thereby to move components other than the analysis target into the second receptacle via the filter; and a positive pressure section configured to apply a positive pressure from the second receptacle side to the filter to which cells being the analysis target are attached.
