Beijing Superior Chemicals and Instruments

Beijing Superior Chemicals and Instruments Co., Ltd. was a prominent Chinese distributor specializing in life science research products, laboratory instruments, and chemical reagents. Established in 1998 and headquartered in Beijing, the company served as the primary distributor for Sigma-Aldrich in the People's Republic of China, catering to academic, clinical, and industrial sectors. In April 2006, the company was acquired by Sigma-Aldrich Corporation to establish a direct sales and distribution network across China, including key locations in Shanghai and Guangzhou. Following the 2015 acquisition of Sigma-Aldrich by Merck KGaA, the company's operations were fully integrated into Merck's Life Science business division, now operating under the MilliporeSigma brand.
