摘要：

对紫外-可见分光光度计（岛津UV-1750）进行简单的改造，实现了其对样品的在线检测并应用到实验教学中，该改造也适用于岛津UV-1780等。紫外-可见分光光度计的改造拓展了仪器的功能，提高仪器利用率；在实验教学中，改造后的紫外-可见分光光度计可以成为蛋白部分收集系统的一部分（替代传统的蛋白检测仪和记录仪），减少实验室仪器的购置成本。

Abstract:

In this paper, the UV-Visible spectrophotometer (SHIMADZU UV-1750) was simply modified to realize the on-line detection of samples and applied to laboratory teaching. The modification is also applicable to SHIMADZU UV-1780 and other models of spectrophotometer. The modification expands the function and improves the utilization rate of the instrument. In the laboratory teaching, the modified UV-Visible spectrophotometer can become a part of the protein collection system (replacing the traditional protein detector and recorder), thus reducing the acquisition cost of laboratory instruments.

Key words: UV-Visible spectrophotometer, Functional expansion, Laboratory teaching
