Dispensation tip, reaction kit using the same, and dispensation tip drive mechanism

摘要

A surrounding environment and a solution to be dispensed are prevented from being polluted by aerosol inside a dispensation tip. A dispensation tip 20 is provided with a dispensation nozzle 19 attached to its distal end, a syringe having a hollow inner portion, that is connected to a proximal end of the dispensation nozzle 19, and a plunger 22 that is allowed to slide in the cylinder 21 of the syringe so that suction and discharge processes are carried out on the liquid by the dispensation nozzle 19. A separation member having airtightness for separating an inside of the nozzle 19 from the outside and flexibility for allowing the plunger 22 to freely slide is placed between the proximal end of the plunger 22 and the proximal end of the cylinder 21.
