  • Sublimation screening test and apparatus
    Patent number: 7179656
    Abstract: Disclosed is an apparatus for rapidly screening chemicals for their ability to sublime. The apparatus consists of a heated well plate, where the chemicals are deposited, and a cooled finger plate, holding fingers that penetrate each well. The two plates touch at only the perimeter in order to facilitate a vacuum seal and to reduce any thermal transfer.
