Provided is a dispensing device that can dispense at a high speed and with high precision and that can be miniaturized. This dispensing device suctions a liquid sample into a disposable tip and discharges the suctioned liquid sample, the dispensing device being provided with: a piston receiving part into which a piston is inserted; a tip detachment part that detaches the disposable tip mounted on the front end of the piston receiving part by pressing down the disposable tip; and a force action part that works in tandem with the tip detachment part and moves in the direction opposite to the movement direction of the tip detachment part.

Dispensing device, tip mounting method, and tip removing method

A thermal cycler includes: a support block configured to support a reaction vessel; a Peltier element thermally connected to the support block and configured to adjust a temperature of a sample solution stored in the reaction vessel by heating/cooling the support block; a temperature sensor configured to measure a temperature of the support block; and a temperature adjusting unit configured to control a current and a voltage supplied to the Peltier element based on the temperature of the support block measured by the temperature sensor. As the reaction vessel, a reaction vessel including a conical portion which opens at an upper portion and tapers toward a lower portion is used, and the Peltier element is arranged so as to be parallel to a conical generatrix portion of the reaction vessel.
