Cooler for obtaining crystals

Abstract

A modular air‐cooled tube, with a series of movable Tamman test tubes or plugs (modular unilateral and bilateral “crystallization comb”), installed in a laboratory tube furnace is presented. The setup allows easy regulation and simultaneous crystallization tests of a series of different crystallization parameters in crucible columns, enabling rapid acquisition of crystals. The relationship between the crystallization parameters has been given and numerically analyzed. This method can also be applied in crucible and chamber furnaces. (© 2011 WILEY‐VCH Verlag GmbH & Co.
