Abstract
A sample handler moves and positions sample tube racks in an analytical instrument. The sample handler has an in-feed and out-feed that advance sample tube racks using a walking beam mechanism. Sample tube racks are seated within the in-feed and are transported onto a cross-feed. The cross-feed comprises a movable track having a platform mounted thereto. The platform includes spring loaded gripper fingers that engages and secures the sample tube rack to the platform. The cross-feed moves the sample tube racks to a point where they are accessed by the analytical instrument. Thereafter, the cross-feed moves the sample tube racks to a position behind the out-feed where the walking beam mechanism moves the tube racks out of the analytical instrument.
