A furnace, in particular for an electro thermal atomization device of an atom absorption spectrometer, has a heatable heat duct in which is mounted a trial platform. The trial platform is essentially basin-shaped with radially inward-turned rims, at least at its free ends. In order to make ongoing improvements in a furnace of the aforementioned type, so that the trial platform has an increased lifetime along with high reproducibility of measurements and simple operation as well as low cost, the trial platform features a geometric structure stabilization device which reduces the ratio of effective volume of the trial platform to the rim volume.
This is a continuation of copending U.S. patent application Ser. No. 10/167,788 filed on Jun. 12, 2002 now U.S. Pat. No. 6,894,776, which claims priority of German Patent Application 10128272.9 filed on Jun. 12, 2001.
