摘要

[PROBLEMS] A dispenser for a microchip, discharging liquid without generating an air layer in a well and without the use of a complex control mechanism. [MEANS FOR SOLVING PROBLEMS] The dispenser is provided with a well(11) having an opening (11a) in its upper end, capable of containing liquid (F) in it, and discharges the liquid (F) into the well (11) of a microchip (10) having inside a microchannel (13a) communicating with the lower end of the well (11). The well (11) has at its lower end a well bottom (14a) that is an annular step projecting inward of the well. The dispenser discharges the liquid (F) from a tip opening (2a) after a dispenser nozzle (2) is moved downward up to a position where the tip opening (2a) is located at the well bottom (14a).
