Abstract: A method of providing sample containers with an automatically readable identification for an analysis device, in which the sample container may be heated to an operating temperature for analysis. It is the object of the invention to improve the identification of sample containers in a manner that the sample contained in the sample container is not contaminated by the constituents of the identification agent during analysis. The object of the invention is solved in that the identification is applied at an elevated temperature above the operating temperature. By the method according to the invention, volatile constituents of the identification agent are advantageous evaporated so that when using the sample container during operating temperature of the analysis device, the sample to be analyzed is no longer contaminated by the exhaling constituents of the identification agent.

It is the object of the invention to improve the identification of sample containers in a manner that the sample contained in the sample container is not contaminated by the constituents of the identification agent during analysis. The object of the invention is solved in that during the manufacturing process of the sample container, the identification is applied during the final cooling phase of the ready sample container in a temperature interval between a maximum temperature during the sample container manufacture and the operating temperature.

Abstract: Closure for a sample vial utilized to introduce sample into a gas chromatograph in accordance with the head space method. The closure includes a flexible disc for closing the opening through the neck of the vial and overlying the margin of the neck about the vial opening. A cap having a central aperture defining an annular shoulder about the aperture overlies the disc. The cap has an annular depending skirt encompassing the disc for clamping about the neck of the vial to retain the disc and the cap on the vial. A portion of the closure is deformable for venting the vial to atmosphere in response to a pressure within the vial when the closure is applied thereto in excess of a predetermined pressure.
