Abstract：The status and function of large-scale equipment in the university laboratories was introduced in the present paper. Around
the service life of large-scale equipment, the survey of the use of large-scale equipment in fifteen universities was carried out. The
relatively large number of liquid chromatography, microscope and other 10 kinds of equipment as the research object were screened out.
According to their respective purchase time, and using the least square method, the average service life of different types of large-scale
equipment was predicted, and the several points to extend its service life were put forward, which was of great reference value for carrying
out the life cycle management of large-scale equipment, and perfecting the management system of large-scale equipment.
