<p>Apparatus for use in analytical instruments such as autosamplers comprises a tapered vial and a sleeve. The sleeve includes an annular inner frustoconical portion (7) which receives the closed end of the vial to locate it in an operative position of an autosampler. The portion (7) may include a cylindrical extension for precisely defining the axial height of the vial relative to the sleeve, and hence the instrument. <IMAGE></p> |
