Abstract
A microwave-based apparatus for rapid digestion of a sampel by a Kjeldahl method is provided which includes a reaction vessel surrounded by an insulator in the form of, for example, a cup. The reaction vessel is disposed in the internal chamber of a microwave system, which includes a wall having an aperture. A connector tube is slidably disposed in the aperture, wherein one end of the tube is connected to the mouth of the reaction vessel, and the other end is connected to a suction device external to the chamber. A biasing element is provided outside the chamber to assist in joining the slidable connector tube to the mouth of the vessel, yet enabling removal of the vessel from the chamber without detachment of the biasing element.
