在制备、检查植物材料中应用国产CS-1型低温工作台的一些特点

Application of a New CS-1 Cryogenics Stage System in Plant Sample

装在KYKY-AMRAY-1000B扫描电镜上的国产CS-1型低温工作台,它用液氮泥作样品快速冷却剂。在样品转移过程中采用隔离大气式的密封转移器。用它制备含水丰富的、娇嫩的植物鲜活材料,具有样品表面不裹霜、细胞里面不产生冰晶、赝象小、能保持样品在生活状况下的三维形貌等特点,故能在扫描电镜里对用液氮冷却的样品台上的样品作较长时间的仔细观察。并能正确反映元素在细胞里的含量和分布。制样迅速方便,有简易的断裂和蚀刻装置。

The KYKY-AMRAY-1000B Scanning Electron Microscope's Cryogenics Stage System CS-1 is usefulthe nitrogen slush as the speedy coolant. During the process of transfering the sample, the closed don't frost.The sample on the sample stage freezed by liquid nitrogen can be observed for a long time. To the aqueous freshdelicate plant sample treated by the CS-1 system, there is neither frost on the surface of the sample nor icebreccia in the cells. The sample can keep both the three-dimensional figures in the living and the content anddistribution of elements in the cell. The CS-1 system have two other virtues, preparing the sample speedy andeasily and having a simple breaker and a exact defroster.
