Abstract:
1. A cryogenic specimen holder which receives, cools and positions a specimen in at least one of an imaging and analytical device, said holder comprising: a receptacle for receiving and supporting said specimen; a reservoir for storage of a liquid cooling medium; a flexible thermal conductor forming at least a portion of a thermal connection between said receptacle and said reservoir; an elongated barrel mounted between said reservoir and said receptacle for positioning said specimen at a preselected location within said at least one of said imaging and analytical device; a thermally conductive connecting rod thermally and physically affixed to said receptacle, mounted externally from said reservoir, axially within and thermally isolated from said elongated barrel, forming at least a portion of said thermal connection between said receptacle and said reservoir; and an actuator affixed to said connecting rod for selective axial displacement of said connecting rod within said barrel, causing axial displacement of said receptacle for selective extension of said receptacle exterior to said barrel and retraction of said receptacle interior to said barrel.
