Abstract
A specimen carrier includes an elongate member defining an external sealing surface and a support surface upon which a specimen can be carried, the elongate member including a first material having a first coefficient of thermal expansion. The specimen carrier further includes a cap configured to be passed over a portion of the elongate member to close a region of the cap that surrounds the specimen when the cap is passed over the portion of the elongate member, the cap defining an internal sealing surface formed complementary to the external sealing surface, and the cap including a second material having a second coefficient of thermal expansion that is greater than the first coefficient of thermal expansion. When the elongate member and cap are together placed in a cooling substance, the internal sealing surface of the cap compresses the external sealing surface of the elongate member to form a hermetic seal.
