为您的实验室选择旋转蒸发仪的提示

旋转蒸发是通过在高温和减压下将溶剂以薄膜形式分布在容器内部的方式来减少溶剂体积的方法,该方法可促进从挥发性较小的样品中快速去除多余的溶剂。旋转蒸发仪用于化学实验室。该仪器使用蒸发技术从样品中轻轻有效地去除溶剂,包括许多有机,无机和聚合材料。化学家Lyman C. Craig在1950年**了一种简单的旋转蒸发仪系统。它于1957年由瑞士公司Büchi**次商业化。

旋转蒸发仪如何工作?

旋转蒸发器或“ 旋转蒸发器 ” 的主要组件包括电机单元,蒸气管道,真空系统,加热的液浴,带有使冷却剂通过的盘管的冷凝器或“冷指”,冷凝水收集瓶和机械或电动机构。在旋转蒸发仪中,电动机旋转装有用户样品的蒸发瓶或小瓶。蒸气导管是样品旋转的轴,并且是用于将蒸气从样品中抽出的真空密封导管。真空系统大大降低了蒸发器系统内的压力。真空系统可以像带浸入冷水槽中的疏水阀的抽水机一样简单(用于无毒溶剂),也可以像带冷冻疏水阀的可调节机械真空泵一样复杂。通常为水的加热液浴加热样品。旋转蒸发器中使用的冷凝器可以是简单的,也可以是复杂的,具体取决于蒸发的目标以及溶解的化合物可能给混合物带来的任何倾向。冷凝液收集瓶位于冷凝器的底部,在重新冷凝后捕获蒸馏溶剂。
