The lab water purification solution of Qiqin covers a full range of products including central water purifiction system and ultrapure water machine. Qiqin provides integrated water supply, intelligent control, and data traceability for laboratories of research institutes, universities, medical institutions, food and drug testing, chemical analysis, microelectronics research and development, pharmaceuticals, and environmental monitoring.

We provide a complete solution for biopharmaceutical purified water. The biopharmaceutical purified water system follows a modular design concept, based on functional units such as pretreatment, oxidation disinfection, multi-media filtration, reverse osmosis, UV disinfection, EDI continuous deionization, water storage and distribution. In the design, manufacturing, and commissioning process, advanced technology, exquisite craftsmanship, and strict quality control are implemented in each functional unit.

Qiqin provides modular treatment and intelligent control services for complex wastewater containing acids, bases, heavy metals, organic solvents, and biological pollutants generated in laboratories of research institutes, medical institutions, and educational institutions, ensuring stable and compliant discharge of effluent.

The Qiqin direct drinking water system solution adopts multi-stage filtration, UV sterilization, and circulating water supply technology to provide safe, healthy, and convenient centralized direct drinking water supply for public places such as schools, hospitals, office buildings, and industrial parks, completely bidding farewell to bottled water and decentralized water dispenser models.
