A glass-cell vial is provided which can examine specimen without causing any hindrance even when as minimum as possible specimen is used, and prevents mixture of foreign substances from causing examination errors. A vial is provided which comprises function of cell capable of optical examination, and the inner surface of bottom of the vial is formed to be a round-state convex part upwardly and the outer surface of the bottom is formed to be in convex state. When a small amount of liquid specimen is introduced into this cell vial, a part which can be a light irradiation part for optical examination can be positioned between the meniscus part of the liquid specimen and the upper end of the inner bottom. Consequently, it becomes possible to examine light quantity variation even though the specimen is in small amount.
A glass-cell vial which is provided with cell function enabling of performing optical examination, comprising a structure that inner surface of bottom of the vial is formed to be a round-state convex part upwardly and outer surface thereof is formed to be in convex state downwardly so that light irradiation part for optical examination can be positioned between meniscus part of liquid specimen and upper end of the bottom and light can pass through to the liquid specimen.
