Shanghai Juna Technology Co., Ltd. is a modern high-tech enterprise that integrates science, industry, and trade. It has multiple production factories and trading companies, mainly engaged in solar energy, optical communication, biochemistry, international trade, consumables and accessories, and other businesses. The company is divided into Optical Communication Division, Solar Energy Division, Scientific Instruments Division, Biochemical Instruments Division, International Trade Division, and Consumables and Accessories Division. Main products: 1. The company's Biochemical Instrument Division was formerly a professional biochemical instrument factory that integrates development, design, production, sales, and service. It has strong technical strength, advanced production equipment and processes, a sound management system, and high-quality after-sales service. Since its establishment more than 20 years ago, we have focused on absorbing advanced German technology and continuously adopted new technologies, materials, and processes to develop over 100 products in various series, including rotary evaporators, low-temperature tanks, vacuum pumps, super constant temperature tanks, freeze dryers, incubators, oscillators, mixers, centrifuges, water baths, and more. The products are sold well in universities, hospitals, chemical, biochemical, epidemic prevention, environmental protection and other research institutions across the country, and are exported in large quantities to countries and regions such as Germany, Pakistan, Indonesia, Spain, the United Kingdom, Brazil, Taiwan, etc. 2. The Optical Communication Division has developed a series of high-quality and low-cost erbium-doped fiber amplifiers (EDFAs) suitable for scientific research and practical use in optical communication systems, based on technologies such as "Low Noise Index Gain Clamp Erbium Doped Fiber Amplifier" and "Fiber Bragg Grating Enhanced L-band Dual Pass Erbium Doped Fiber Amplifier". The technology has reached the international advanced level. At the same time, as the agent of Santec Corporation, a well-known optical communication company in Japan, for its optical communication series products in China. 3. The Solar Energy Division is mainly engaged in the research, development, production, sales, construction, and service of solar cells, solar photovoltaics, and solar module related products.
