PURPOSE:To avoid the nozzle contamination after washing, by setting apart the inserting position of the soiled nozzle and the take-out position of the nozzle after washing each to the washing bath and thus preventing the contamination of the drying mechanism. CONSTITUTION:In washing bath 6, the inserting position of nozzle 3 is set apart to the position of drying mechanism 7 attached on the upper surface of the take-out opening of nozzle 3. Each sucking container 1 is positioned like the one-dot-chain line C at the position where nozzle 3 discharges the specimen to each distribution tube 5. Then pressure reduction pipe 2 of each nozzle 3 is displaced like the arrow mark to lower down at inserting position A of the washing bath and then pass through bath 6 like the arrow mark B. Thus nozzle 3 is washed. After washing, nozzle 3 is taken out through the take-out opening to then receive the water drain- off and drying via mechanism 7 provided at the upper part of the take-out opening. Thus no contamination is given to the drying mechanism at all since the inserting position of nozzle 3 is apart from the position of mechanism 7. Accordingly, the contamination can be avoided for the nozzle after washing. |
