Abstract
An automatic preparation apparatus has turntable means in which a plurality of test tubes can be disposed in radial direction, filter robot means which can move a releasable filter onto one of those test tubes, and probe robot means which can sample the liquid contained within one of the test tubes and inject a predetermined amount of liquid into another one of the test tubes and filter. Furthermore, the apparatus comprises control means for controlling those means in accordance with a predetermined sequence to effect a desired preparation. The probe robot means has a support arm member for supporting the filter. The support arm member includes a head section having a filter retainer mechanism for releasably retaining the filter and a sealing mechanism for forming a sealing chamber on a sample-injecting side of the filter, an arm section having an end tip portion connected to the head section and a rear end portion attached to a support post member, and a device for detachably connecting the head section to the arm section.
