Due to its late start, the domestic instrument industry is not as mature as foreign countries, and semi-automatic or fully automatic pipetting systems have basically monopolized the market. The current gap between China and foreign countries is not in the implementation of many functions, but in the control of accuracy. Although there is a gap, there are still some entrepreneurs and researchers in China who are silently studying and blindly believing in foreign products. The instrument cost, consumables cost, and maintenance cost of foreign products are very high, and the relevant contract terms lack flexibility, which cannot fully consider China's national conditions. With the improvement of domestic research and development technology, more and more domestic brands have appeared in major laboratories. In recent years, The policy of supporting domestic medical equipment is frequent, and under the main theme of "import substitution", we believe that the spring of domestic instruments is coming soon.
