Hunan Kaida Scientific Instrument Co., Ltd. is a wholly-owned high-tech subsidiary established by Kaida Group with an investment of 12 million yuan in Changsha. It specializes in the research and production of laboratory centrifuges, medical centrifuges, and laboratory instruments. It has passed ISO9001:2008 international quality management system certification, ISO13485 certification, and European CE certification. All research personnel in the company have a bachelor's degree or above, including one doctoral degree. Backbone researchers have been engaged in the research and development of centrifuge products for more than 20 years, conducting a series of in-depth studies on the core technologies of medical centrifuges and laboratory centrifuges, such as rotor photoelastic tests, resistance strain measurement tests, axisymmetric finite element method theoretical calculations, thermodynamic calculations, aerodynamic calculations, etc. They have developed a new generation of low-noise centrifuges that are easy to operate, safe, and reliable, such as variable frequency motor drives, microcomputer program control, and environmental temperature control. The company continuously introduces and absorbs new foreign technologies and cooperates with key domestic universities and research institutions to keep up with the world's advanced level in product technology. Currently, it produces 23 series of laboratory centrifuges and medical centrifuges, including high-speed centrifuges, low-speed centrifuges, cryogenic centrifuges, and large capacity centrifuges. It is the first in Hunan Province to obtain the first-class medical device production record, with record number: Xiangchang Food and Drug Supervision Equipment Production Record No. 20150007. Kaida Centrifuge Factory has always adhered to the product development concept of "continuous innovation", and was the first to launch the K series fully automatic rotor recognition centrifuge in China. As soon as the K series centrifuge was launched, it continuously received orders from high-end customers and received high praise. Because centrifuges with fully automatic rotor recognition systems can automatically identify the highest speed and maximum centrifugal force corresponding to the rotor, operators do not need to search and manually select the rotor number, which means saving time and improving efficiency; Especially, it can prevent the use of the wrong rotor number, prevent the risk of rotor overspeed (which can lead to shaft breakage and rotor explosion), and ensure the safety of the machine, samples, and operators. The centrifuge and other instruments of Kaida Laboratory have won a good reputation in the industry for their excellent quality and good service. They have been widely used in colleges and universities, research institutes, biopharmaceuticals, health systems, agriculture, animal husbandry and fishery systems throughout the country. They have designated one of the three major foreign aid brands for the Ministry of Commerce of China, and are also exported to more than 30 countries and regions in the world, including the United States, Germany, France, Italy, Poland, Russia, Australia, Türkiye, Saudi Arabia, Egypt, India, Pakistan, Singapore, Indonesia, Sri Lanka, Hong Kong, Peru, Cuba, Brazil, etc.
