    • 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.
    • 试样载体包括细长构件,该细长构件限定了外部密封表面和支撑表面,样品可以被承载在支撑表面上,细长构件包括具有第一热膨胀系数的第一材料。 所述样本载体还包括帽,所述帽被构造成当所述帽通过所述细长构件的所述部分时,穿过所述细长构件的一部分以封闭所述帽的包围所述样本的区域,所述帽限定形成的内部密封表面 互补于外部密封表面,并且帽包括具有大于第一热膨胀系数的第二热膨胀系数的第二材料。 当细长构件和盖一起放置在冷却物质中时,盖的内部密封表面压缩细长构件的外部密封表面以形成气密密封。
