The sample device includes a magazine having a rotatable turntable carrying a plurality of circumferentially spaced chambers for receiving sample vessels and movable axially between a sample changing positon and a sampling position. In the sample change position, each sample vessel is pushed against a laterally displaceable closure plate to uncover an aperture in a bottom closure member whereby the sample vessel is receivable in a chamber registered with the aperture. A cradle is carried by the bottom closure member to support the sample vessel as it is displaced through the aperture into the registering chamber. When a selected vessel is aligned with a sampling opening through a closure plate on the opposite side of the turntable, the magazine is displaced axially into the sampling position with the axial displacement causing a needle to pierce the self-sealing diaphragm on the sample vessel. Sampling is effected by pressurizing the vessel and drawing sample components in the vapor phase into the injection block of the gas chromatographic instrument.
