Abstract
An analyzing apparatus has a transfer device having a movable gripper, a pipetting device having a movable nozzle and a measuring unit. One of a plurality of tips arranged on a tip rack and one of a plurality of vessels arranged on a vessel rack are held by the gripper to be set in a tip holder. A nozzle pushes the tip on the tip holder to connect to the tip. A sample and reagents are delivered into a vessel on the tip holder by the tip connected to the nozzle. The used tip is detached from the nozzle. The vessel containing a reaction mixture is transferred to a sucking position with the gripper after incubation, and the reaction mixture is introduced into the measuring unit. The used vessel is transferred to a waste box with the gripper.
