Abstract

PURPOSE: To enable general-purpose, highly efficient separation by using a spherical bag made of flexible thin film as a barrier for separation, in which liquid having intermediate specific gravity between two phases of liquids to be separated and a thixotropic gel-like substance are contained.
CONSTITUTION: A thin film bag 5 made of natural or synthetic rubber latex, polyvinyl chroride etc. is placed in a tube 6 and centrifugal separation is performed. Liquid such as water or alcohol and at least a kind of substance selected from thixotropic gel-like substances such as a mixture of silicone and silica are put into the bag 5. The specific gravity of liquid contained in the bag is made intermediate between the two phases of liquids to be separated. By this way, the bag 5 sticks closely to the wall of the tube during centrifugal separation to enable perfect separation.
