Nanjing Quankun Biotechnology Co., Ltd., as a domestic supplier of laboratory/industrial ultrapure water equipment, specializes in the research and development, production, and sales of laboratory ultrapure water instruments, as well as providing complete solutions for laboratory pure water systems. The company adheres to the business philosophy of "innovation and pragmatism, excellent products, attentive service, and integrity-based", and is committed to providing customers with high-quality products, professional technical support, and excellent after-sales service. Quankun has a professional research team, a professional after-sales service system, and a large-scale production base in China. Its technological innovation strength is very strong. Through years of development in the field of water treatment and the introduction of advanced foreign water treatment technology, the BDP series ultrapure water equipment has been produced. It integrates water treatment technologies such as reverse osmosis, nanofiltration (NF), ultrafiltration (UF), microfiltration (MF), ion exchange, ultraviolet oxidation (UV), and terminal modification developed by NASA to completely remove ions and organic matter from water. The export is tested by high-precision online resistivity meters to display the quality of the produced water in real time, ensuring that users can use it with confidence. The effluent quality has fully reached the theoretical purity limit of water, and the water quality meets the first level standard for laboratory water in China (GB/T 6682-2008), the first level standard for drug testing water of the National Society of Clinical Pathology in the United States (CAP TYPE I), as well as multiple international standards such as ASTM and NCCLS in the United States. Becoming an ideal water system for industries such as life sciences, analytical chemistry, pharmaceuticals, and electronics. Having gained recognition from research institutions, monitoring, biomedicine, healthcare, electronic power, smelting, chemical engineering, high-precision materials and other industries, we have become a market pioneer in the field of laboratory ultrapure water in China after years of development.
