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
