In order to protect the global environment, we are actively working on the development and production of energy-saving and environmental protection pure water inlet ultrapure systems, commercial lab water purification device, lab reverse osmosis equipment. Our company can combine different technologies, talents, products and strategies in a slightly different way, so that our company can obtain more profits and become more successful. We adhere to the core values of "customer first, pursuit of excellence, people-oriented, long-term benefits" and establish the corporate philosophy of "market is the foundation, development is the outline, innovation is the soul". We make the best match between employee needs and corporate needs, so that employees can grow together with the company.
With LCD controlling system, 2 way water quality sensors, timing and quality dispensing, single stage RO system, 1 pump, and built-in 12 liters tank, Eco-S series ultrapure water system is economic choice of ultrapure water for high grade experiments.
With tap water inlet, its output ranges from 15 to 30 liters/hour. It can produce single stage RO water and ultrapure water. The single stage RO water’s ion rejection rate is more than 97%, and the ultrapure water’s resistivity absolutely reaches to 18.2MΩ.cm. It completely meets the highest grade I standard of ASTM, CAP, CLSI, EP and USP.
