小样品升降温控制装置

A Cooling and Rewarming Device for Microsample

一种微电脑控制的小样品升降温控制装置，包括超快速降温部分以及升温和慢速降温部分。它能以０～６×１０４Ｋ／ｓ的升温或降温速率，使小样品从常温降到低于１５０Ｋ以下的低温状态，或从１５０Ｋ以下的低温升温到常温状态，该装置不仅可用于生物材料的低温保存研究和电子显微镜生物样品的低温制备，也可用于食品的冷冻保鲜研究以及超导材料、光电敏感元器件低温性能研究。

A cooling and rewarming programmabledevice for microsample consists of an ultrarapid cooling part, a rewarming and slow cooling part.With the device a microsample can be cooled from the ambient temperature to the low temperature below 150 K and can be rewarmed from the low temperature to the ambient temperature at a 0￣6×104 K/s rate. The device can widely be used to investigate the cryopreservation of biomaterial, the biospecimen cryopreparation for electron microscope, the food frozen preservation and the cryogenic properties of super-conductor elements and electronic or optical detectors and etc.
