Abstract: With the rapid development of information technology, virtual simulation devices, as an innovative teaching method, are gradually penetrating and profoundly changing traditional medical education, especially in the field of molecular biology laboratory technology teaching. This article aims to explore the practical application of virtual simulation equipment in teaching in this field and its educational value. Through specific case analysis, it is found that virtual simulation equipment promotes the visualization and simulation training of key experimental steps such as gene cloning and PCR amplification. In the teaching of inspection technology, it can strengthen the cultivation of practical abilities such as instrument operation, quality control, and data analysis; At the same time, it reflects on the challenges and future development directions in the current application process, emphasizes its important potential as a modern educational tool, and its important role in improving teaching quality and cultivating students'innovative abilities.
