Abstract:
1. A reagent preparation apparatus for supplying a reagent, prepared by mixing a concentrated reagent and purified water produced from water by a purified water production device including a valve configured to stop/start a supply of water into the purified water production device, to a sample measurement device for measuring a sample using the prepared reagent, the reagent preparation apparatus comprising: a reagent preparation unit comprising a purified water storage unit and a chamber, a processor, communicably connected to the purified water production device, and programmed to: wherein the processor is further programmed to control the purified water production device to continue producing the purified water until a predetermined time has elapsed from when the purified water production device starts the production of the purified water, by not transmitting the stop instruction to the purified water production device until the predetermined time has elapsed from the transmission of the start instruction, even if amount of purified water in the purified water storage unit reaches the predetermined amount, and wherein the purified water production device starts the production of purified water in response to a start instruction transmitted from the reagent preparation apparatus by opening the valve and stops the production of purified water in response to a stop instruction transmitted from the reagent preparation apparatus by closing the valve.
