Abstract

PURPOSE:To constitute a device of preventing the waste of sample by sucking and discharging the sample, reagent, washing liquid and waste liquid by means of two pieces of changeover valve bodies which have flow passages and communicating holes and slide while contacting with each other liquid tightly. CONSTITUTION:Changeover valve bodies A, B having communicating holes and flow passages slide each other liquid tightly. In the position of the figure, a nozzle 6 is lowered and is put into a sample vessel 2 and a pisto 45 is pulled to suck a prescribed amt. of soln into a metering cylinder 9 and to suck the same amt. of the sample 5. The nozzle 6 is pulled up, and the valve body A is turned left to communicate communicating holes 1 and 22. In this state the cylinder 9 is moved upward and the sample 5 in the tube is shifted into sample holding tube 3, thence the piston 54 is pulled to suck thesoln. from a vessel 33. Thence, the valve body A is returned to the home position, and the soln. in a reagent soln. containing vessel 57 is pumped 11 into the tube 3 which is next fed together with the sample 5 to a reaction system 17. A pisto 54 is moved upward to feed the soln. into a evacuation chamber 58, and the inside of the tube is washed. Thereby, the waste of the sample is eliminated and the device particularly suitable for a smallamt. of the sample is constituted.
