LYOPHILIZED MATERIAL PRODUCTION METHOD

摘要

A lyophilized material production method according to the invention is a lyophilized material production method for producing a lyophilized material by lyophilizing a reagent containing an additive at a lyophilization temperature, and includes a freezing step in which the reagent containing an additive is cooled with a low-temperature liquid whose temperature is lower than the lyophilization temperature, a maintaining step in which the temperature of the frozen reagent is increased to a temperature higher than the boiling point of the low-temperature liquid and the reagent is maintained at the temperature for a predetermined time, and a lyophilization step in which the reagent having been maintained for a predetermined time after increasing the temperature of the reagent is dried at the lyophilization temperature under reduced pressure.
