Abstract

An apparatus and a method for transfusing liquid specimen for an optical characteristic measurement, which is excellent in operability and handling, and capable of introducing a liquid specimen into a sample cell without detaching the cell from an optical characteristic measurement apparatus and without bubbling, as well as a polarimeter are disclosed. According to the present invention, the specimen can be introduced into the sample cell without detaching the sample cell from the equipment, in a way of connecting the bottom of the sample cell with a reservoir for temporarily accommodating the liquid specimen through a tubular path, then varying a difference in the levels of the sample cell and the reservoir, or a way of using a syringe arranged in the tubular path. At expelling the specimen from the sample cell, the specimen is transfused into the reservoir in a similar manner.
