PURPOSE:To enable reduction in time for pretreating specimens by attaching vertically movably test tube holders to the shaft of a rotor, providing a device for lifting said holders, a mechanism for moving the holders and a detector for attachment and detachment of test tubes and providing a control device for these devices. CONSTITUTION:An automatic analyzing system for specimens is constituted of a part 1 for pretreating the specimen, a part 2 for controlling driving, a sample nozzle mechanism part 3, an analyzing part 4 and a part 5 for processing data. A rotor 13 is freely rotatably fitted to the main unit of the part 1 and is connected to a main motor 14 to perform centrifugal sepn. by high speed revolution. Test tube holders 15 are provided vertically movably and swingably up 45 deg. to the outside circumferential part. A mechanism 17 for lifting the test tubes is provided under the holder 15 and a detector 19 for the test tubes by photodetection is provided in the upper part. The mechanism 24 for rotating and moving test tubes 16 is constituted of a friction disc 26 and a clutch mechanism. The pretreating stage is thus accomplished in short time even in emergency inspection and the exact automatic analysis is made possible. |
