ABSTRACT:
This invention is an apparatus for supporting a plurality of sample preparation cartridge units to expedite the handling of sample preparation. The apparatus comprises a pair of plates in space parallel relation. The first plate is mounted on end posts and the second plate is supported over the first plate by apparatus which adjustably raise and lower the second plate. The first and second plates are provided with notches along the longitudinal sides of the plates which are in vertical alignment. An elongated bar is hingedly connected between the plates and provided with apparatus to lock along the longitudinal side of the plates. The sample preparation cartridges which generally comprise a cylindrical body and cylindrical stems concentrically extending from the cartridge body, are placed between the plates so that the stems enter vertically aligned notches. The elongated bars are moved to laterally abutt against the cylindrical bodies of the cartridges and locked into place so that the cartridges are fixed vertically between the plates and laterally between the notches and the bars. A plurality of cartridges may thus be supported during the column separation stage.
