Yantai Kehui Instrument Co., Ltd. was established in Yantai, Shandong in 2015 with a registered capital of 2 million RMB. It is a private enterprise that sells specialized equipment and tools for the pharmaceutical preparation industry. Both initiators have been engaged in drug formulation research and development, teaching, and production for several years (one initiator has been engaged in the research and development and production of long-acting sustained-release formulations such as microspheres and nanocrystals for 6 years, and the other initiator has been engaged in the research and development and teaching of conventional dosage forms such as tablets, capsules, granules, and injections for 13 years). They are well aware of the accelerating role of reliable equipment and tools in drug formulation research, teaching, and production. However, the current market performance of specialized equipment and tools in the domestic pharmaceutical preparation industry is that there are numerous manufacturers, with a single manufacturer having a wide range of products but no flagship products, and a low degree of specialization; In pursuit of price advantage, shoddy production and poor product quality; High priced and low-quality products fill the market, and manufacturers act as high-quality products through marketing or packaging, selling them at high prices; Low end homogeneous products dominate. Due to the above phenomenon, it seems very difficult to purchase a satisfactory drug preparation specialized equipment and tools. Sometimes, even if it takes several days or even longer to conduct specialized research, it is often not possible to achieve the desired outcome. Without exception, the two founders of Yantai Kehui Instrument Co., Ltd. have also experienced this situation and, by chance, had the idea of changing this predicament. Thus, Yantai Kehui Instrument Co., Ltd. was established. The original intention of Yantai Kehui Instrument Co., Ltd. was to provide customers and pharmaceutical preparation workers with satisfactory specialized equipment and tools. The company currently does not have the manpower and funds to design and manufacture such equipment. But we are also optimistic to see that in the mixed market of fish and pearls, there are still some conscientious manufacturers who are worthy of respect, and there are also some conscientious products that are worth recommending. The goal of Yantai Kehui Instrument Co., Ltd. is to help customers and pharmaceutical preparation workers find such conscientious manufacturers and products. In addition, Yantai Kehui Instrument Co., Ltd. has also selected dozens of commonly used consumables with excellent cost-effectiveness for customers to choose from.
