751G型分光光度计,由于原设计无恒温装置,因此在各种改变温度或维持恒温的实验中使用时受到限制。本文介绍一种恒温水夹套的制作方法,在不需要对仪器作任何改动的情况下,将夹套装入试样室内。用一个实验室常用的超级恒温水浴,泵入恒温水循环,即可使试样室内维持良好的恒温条件,满足一般变温或恒温条件下实验与测试的需要。 751G spectrophotometer, due to the original design without constant temperature device, so in a variety of experiments to change the temperature or maintain the temperature is limited. This article describes a method of making warm water jacketed jacket, without the need for any changes to the instrument case, the jacket into the sample chamber. With a common super-constant temperature water bath in the laboratory, pump into the water cycle, you can make the sample room to maintain good temperature conditions to meet the general temperature or constant temperature conditions for the experimental and testing needs.
