GLONGHUI, March 6 | Libertech (688056.SH) recently said during a survey reception from institutional investors that the company's instrument products generally have a usage cycle of 5 to 10 years. The actual service life of an instrument is affected by multiple factors such as the external environment where the instrument is located and the degree of wear and tear of the instrument itself. At the same time, during customer use, if customers have new application requirements, they may also purchase new products to replace them.
