高等院校的实验室,是培养学生和进行科学研究的重要基地。从经济管理角度出发,本着以最少的投入取得尽可能大的效益的思想,针对学生实验用水需要量大,又要求纯度高这一现状,我们搞了“实验室用小型制纯水装置”,用离子交换树脂制备去离子水。比用市售蒸馏水或用电蒸馏器取蒸馏水,要经济方便,且出水纯度高,出水量大。在此,将该装置介绍如下。此装置所用的交换柱是由两个一万毫升和一个五百毫升的下口瓶代替。装置如图:
Laboratory of higher education is an important base for students and scientific research. From the economic management point of view, in line with the idea of getting as much benefit as possible with the least investment, in view of the fact that students need a large amount of experimental water and require high purity, we engaged in “small-scale laboratory water purification equipment” , Ion exchange resin was used to prepare deionized water. Than the use of commercially available distilled water or electric distiller to take distilled water, it is economical and convenient, and the high purity of water, the amount of water. Here, the device is described below. The exchange column used for this device was replaced by two 10,000-ml and one-hundred-fifths bottles. Device as shown:
