Abstract
A method and device for measuring the osmotic pressure on the basis of an improved supercooling process, whereby and wherein cryohydrate nuclei are made to generate almost spontaneously in a part of a sample liquid by cooling the above part down further to a temperature (to an extra-supercooled state) lower than the temperature of a supercooled state, wherethrough the sample liquid as a whole is induced to freeze statically. Because of a non-necessity of using any stirring rod, it becomes possible to design a small-sized device, to reduce the sample liquid to be used to a possible infinitesimal, and further to perform the continuous measurement with the aid of the adoption of a flow cell.
