Abstract
Provided is an automatic analyzer to control a temperature of a reagent supplied to a magnetic separator with high accuracy. The automatic analyzer includes 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 pipe used to supply the second reagent to the magnetic separator, and a heat exchanger that adjusts a temperature around the pipe. It is preferable that the heat exchanger includes a heat absorption and dissipation unit and a fan that blows air heat-exchanged by the heat absorption and dissipation unit, and the air blown from the fan is blown onto the pipe.

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,
- heat-exchanged air is rectified by the rectifier to be 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.
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 stirrer that rotates liquid after separation in the magnetic separator, wherein
- a heat exchanger is disposed at a position closest to the pipe among the pipe, the magnetic separator, a tip of the discharge nozzle, and the stirrer,
- the heat exchanger includes a rectifier that rectifies air in a direction in which the air is blown onto the pipe, and
- the air rectified by the rectifier is blown onto the pipe, the tip of the discharge nozzle, the magnetic separator, and the stirrer in this order.
