Abstract
A vessel for reducing contamination of liquids is formed of a vessel body with an inlet opening and an outlet opening therein. A closing device is attached to the vessel body adjacent the outlet opening. The closing device closes the outlet opening, and includes a normally closed one-way valve which is openable by a predetermined pressure from within the vessel body.
Claims27
A vessel for reducing contamination of liquids contained therein, said vessel comprising:
- a vessel body having an inlet opening and an outlet opening therein;
- closing means attached to said vessel body adjacent said outlet opening, for closing said outlet opening, said closing means comprising a self-sealing normally closed one-way valve which includes a biasing means which biases said valve in a closing direction toward said outlet opening, said closing means being openable by a predetermined pressure differential between an inside and an outside of the vessel body.
A vessel for reducing contamination of liquids contained therein, said vessel comprising:
- a vessel body having an inlet opening and an outlet opening therein;
- and closing means attached to said vessel body adjacent said outlet opening, for closing said outlet opening, said closing means comprising a normally closed one-way valve, said closing means being openable by a predetermined pressure differential between an inside and an outside of the vessel body,
- wherein said closing means comprises a tubular valve and wherein the tubular valve comprises a tube which covers an outlet opening and extends past the outlet opening, said tube forming a flexible closing member which flexes to allow liquid to escape from said outlet opening.
A method of isolating a component from a sample, said method comprising the steps of:
- filling a vessel with the sample through an inlet opening of said vessel;
- adding a matrix to the vessel, said matrix being selected to allow immobilization of the component;
- incubating the sample and the matrix under selected conditions thereby immobilizing the component;
- and
- removing the sample through an outlet opening of the vessel, said outlet opening being closed by a closing means which elastically biases a closing element against the outlet opening, and which can be opened by a pressure differential between an inside and an outside of said vessel.
A vessel for reducing contamination of liquids contained therein, said vessel comprising:
- a vessel body having an inlet opening and an outlet opening therein;
- closing means attached to said vessel body adjacent said outlet opening, for closing said outlet opening, said closing means comprising a closing element for closing said opening, and a spring means for springably urging said closing element toward said opening in a closing direction.
