Abstract
A dispensing device and an analyzer capable of improving dispensing accuracy as well as improving jamming detection accuracy can be realized by having a short distance between a syringe and a suction tip. The dispensing device 10 includes an upper fixed unit 10A, a lower movable unit 10B which is connected to the upper fixed unit 10A, the movable unit being relatively movable with respect to the upper fixed unit 10A, and a Z-axis movement mechanism 55Z which moves the upper fixed unit to and fro. A syringe 4 and a plunger 13 are held by the upper fixed unit 10A. A tip nozzle 8 is attached to the lower movable unit 10B. An interior space of the syringe 4 and an interior space of the tip nozzle 8 are connected with each other by a connection tube 1 having flexibility.
