  • Publication number: 20100086004
    Abstract: The invention provides, in one aspect, a parallel heat treatment device, including an inner heating chamber defined at least in part by a plurality of heating plate assemblies, each of the plurality of heating plate assemblies including a pair of separate and spaced heating plates. At least one heating element is disposed between each of the pair of heating plates. A test plate is disposed within the inner heating chamber, the test plate being sized and shaped to receive a plurality of sample pans and samples and a temperature controlled support plate is positioned underneath the test plate.

  • Publication number: 20090031826
    Abstract: A high throughput workstation includes: a sample deposition and annealing robot, a pan/sample weighing robot, and a thermal analyzer equipped with autosampler and data analysis system. After deposition, the solvent can be removed and multiple samples annealed simultaneously in a controlled manner. The sample pans are weighed before and after the samples are prepared using a robotic weigher. The high throughput workstation facilitates analysis of thermal properties of samples obtained via parallel plate reaction (PPR) in substantially less time than corresponding manual techniques.

  • Patent number: 5601761
    Abstract: An active material encapsulated in a coating material immiscible therewith is contacted with a solvent that dissolves residual active material on the surface of the coating material without dissolving the coating material. The resultant encapsulated material has improved stability as compared to the material not contacted with solvent.
