摘要： Unused reaction vessels and unused nozzle tips are arranged in a matrix on a vessel magazine and a tip magazine, respectively. A carrying mechanism for moving a gripping mechanism along X- and Y-axes seizes unused nozzle tips on the tip magazine one by one in order, and transfers them to a tip attaching station. The carrying mechanism also seizes unused reaction vessels on the vessel magazine one by one in order starting from one end of the first row. A delivery mechanism, after having attached a nozzle tip on the tip attaching station to a nozzle holder, pours sample and reagent into a reaction vessel on a delivery station. The reaction vessel is carried by a gripping mechanism to an incubator where the mixture of sample and reagent is incubated. After incubation, the reaction vessel is transferred to a shipper station where the reaction solution is extracted by suction with a shipper nozzle which introduces the solution into the flow cell of a measuring device. Prior to the above analysing operation, the gripping mechanism with its fingers kept closed moves about over the delivery station and the incubator for checking presence of obstacle, and disposes it of if one.

摘要： An object of the present invention is to provide a small and compact analytical apparatus. An input/output device for directing the analytical apparatus and displaying analytical results and operation conditions is detachably provided on a body of the apparatus. Since the input/output device can be fixed to an upper position of the body, the apparatus saves space and can be placed on a desk. The analytical apparatus includes a sample disk and a reagent disk. The diameter of the reagent disk is greater than that of the sample disk, and both disks are arranged at the front of the apparatus so that the center of the sample disk is nearer the operator side than the center of the reagent disk. Therefore, the whole arrangement is compact, and the apparatus itself is compact.

摘要： A drop jet apparatus has a nozzle head which defines a pressure chamber, a nozzle, and passages. Part of the pressure chamber is defined by a thin diaphragm which is made thick at the central and at a surrounding portion spaced from the central portion. A piezoelectric plate is adhered to the thick portions so as to bridge the thin portion between the projections.

摘要： An analyzing apparatus comprises a transfer device having a movable gripper (10), a pipetting device having a movable nozzle (29) and a measuring unit (46). One of tips (6) arranged on a tip rack (5) and one of vessels (8) arranged on a vessel rack are held by the gripper (10) to be set in a tip holder (60). A nozzle (29) pushes the tip (6) on the tip holder (60) to connect to the tip (6). A sample and reagents are delivered into a vessel (8) on the tip holder (60) by the tip (6) connected to the nozzle (29). The used tip (6) is detached from the nozzle (29). The vessel (8) containing a reaction mixture is transferred to a sucking position with the gripper (10) after incubation, and the reaction mixture is introduced into the measuring unit. The used vessel (8) is transferred to a waste box with the gripper (10).
