Abstract
A reagent delivery device includes a plurality of delivery syringes, and a plurality of units each having rotary valves by which respective reagent tanks and delivery nozzles are selectively connected with each other and a driving means for driving the rotary valves simultaneously. Further, in the reagent delivery device, the delivery syringes are respectively connected to the rotary valves through the manifold blocks, and a washing liquid is flows through the syringes and manifold blocks. Therefore, if it is necessary to increase the number of reagents to be delivered, such a requirement can be easily dealt with by arranging additional units and manifold blocks without increasing the number of delivery syringes, and contamination between reagents can be eliminated.
