1. An automatic analyzer, comprising:
a magnetic separator that separates a magnetic component and a non-magnetic component from liquid obtained by reacting a sample with a first reagent;
a storage unit that accommodates a second reagent;
a discharge nozzle that discharges the second reagent to a reaction vessel;
a pipe used to supply the second reagent to the discharge nozzle; and
a heat exchanger that adjusts a temperature around the pipe, wherein
the heat exchanger includes a rectifier configured to rectify heat-exchanged air,
a downstream end of the rectifier has a smaller cross-section than an upstream end of the rectifier,
the heat-exchanged air rectified by the rectifier is blown to the pipe, and
a space into which the heat-exchanged air is blown to and a tip of the discharge nozzle are in the same space.
