Abstract

Provided is a method for separating a substance accommodated in a vessel-shaped structure comprising subjecting a vessel-shaped structure 1 , which includes a vessel portion a, a vessel portion b, and a self-fusing material X connecting the both vessel portions, and which accommodates a substance selected from the group consisting of a liquid, a solid a gas, and a dispersion system, to the steps: (i) pulling the vessel portion a and the vessel, portion b away from each other to extend the self-fusing material X; (ii) fusing the extended self-fusing material X together between the vessel portion a and the vessel portion b to separate the accommodated substance; and (iii) cutting a fused part of the self-fusing material X to separate the vessel-shaped structure 1 into a separated structure.

First claim

The invention claimed is:

1. A manipulation vessel for subjecting a sample containing an object component to a predetermined manipulation therein, the manipulation vessel comprising:
a manipulation portion in which a sample containing an object component is subjected to a predetermined manipulation;
a collection portion in which a target substance from the manipulation portion is collected; and
a self-fusing material covering an outer surface of a part including an open end of the manipulation portion and an open end of the collection portion to integrally connect the manipulation portion and the collection portion together, and
the manipulation vessel accommodating a manipulation medium selected from the group consisting of a liquid, a solid, a gas, and a dispersion system as a field for performing manipulation to which the object component is to be subjected.

2. The manipulation vessel according to claim 1 , further comprising a protective member on an outer surface of the self-fusing material.

3. The manipulation vessel according to claim 1 , which is covered with the self-fusing material having a thickness of 0.001 to 3 mm.

4. The manipulation vessel according to claim 1 , wherein the manipulation vessel has a tubular shape, and the manipulation medium is a multi-layered object in which layers of an aqueous liquid and a gel are alternately stacked in a longitudinal direction of the manipulation vessel.

5. The manipulation vessel according to claim 1 , wherein the self-fusing material is selected from the group consisting of isobutylene-isoprene copolymers, ethylene-propylene-diene copolymers, polyisobutylene, paraffin, polyvinyl acetate, polyurethane, polydimethylsiloxane, ethylene propylene copolymers, hydrogel polymers, (meth)acrylic acid ester copolymers, silicone rubber, and natural rubber.
