| abstract |
A method for stabilizing a liquid reagent which comprises superposing, on the surface of the liquid reagent, a layer of an air-barrier substance incompatible with the reagent and having a lower specific gravity than the reagent, such as a chain hydrocarbon, cyclic hydrocarbon, or ether; and a reagent unit which comprises a container, a liquid reagent packed therein, and a layer of the air-barrier substance superposed on the surface of the reagent. Thus, the reagent can be effectively prevented from contacting with air without being affected, and the liquid reagent for use in examination can be stored stably for long after dissolution thereof or opening of the container. |
