Abstract
A device for heating sample containing vials, in a gas-chromatographic apparatus provided with an automatic sampler, which includes a shroud in which a depression is made by a fan which sucks external air and conveys it under pressure into a Venturi tube shaped duct. This depression causes more external air to be sucked through separate openings of the shroud and to follow a different path along the resistors, the sampler, the tray and the vials and to be eventually exhausted through the vent together with air coming from the fan duct.
