METHOD FOR SEPARATING SUBSTANCE ACCOMMODATED IN VESSEL

摘要

Provided is a method for separating a portion (for example, a collection liquid) of an accommodated substance (for example, an operation medium for a physical, chemical, and/or biochemical treatment, and the collection liquid containing a target substance) contained in the same space of a vessel-shaped structure without coming into contact with the external atmosphere and only through a simple mechanical operation. According to the method of the present invention, a vessel-shaped structure (1) comprises a vessel section (a), a vessel section (b), and a self-fusion material (X) connecting the vessel sections, and accommodates an accommodated substance selected among a group of a liquid, a solid, a gas, and a dispersed system. The present invention comprises: (i) extending the self-fusion material (X) by creating an opening between the vessel section (a) and the vessel section (b); (ii) separating the accommodated substance by fusing the extended self-fusion material (X) between the vessel section (a) and the vessel section (b); and (iii) separating the vessel-shaped structure (1) by cutting the fused portion of the self-fusion material (X).
