Abstract
A specimen support for optical observation or analysis. The support comprises a disc-like member composed of a rigid material and having at least one unobstructed hole extending therethrough. When analyzing a liquid specimen, the disc is dipped in the liquid and the surface tension of the liquid will cause the liquid to bridge or span the hole. The support is then placed in a tray or holder and exposed to an infrared beam to generate an infrared spectrum.
