e/Tube furnace

Information
has gloss	eng: A tube furnace is an electric heating device used to conduct syntheses and purifications of inorganic compounds and occasionally in organic synthesis. The usual design consists of a cylindrical cavity surrounded by heating coils, which are embedded in a thermally insulating matrix. The length of the cylindrical cavity is typically 40 - 60 cm, and the diameters are ca. 8 cm. Temperature is controlled via a feedback from a thermocouple. More elaborate tube furnaces have two (or more) heating zones useful for transport experiments. The temperature controllers often allow the operator to program the heating and cooling rates.
