Xinrui Laboratory Ultrapure Water Purifier
[Product Introduction]
The Xinrui Ultrapure Water Purifier uses tap water as the source and integrates technologies such as microfiltration, activated carbon adsorption, reverse osmosis, ion exchange, UV oxidation, and ultrafiltration to remove impurities like ions, pyrogens, organic matter, particles, microorganisms, and bacteria. This process produces pure water that meets the purity requirements for experiments, making it suitable for universities, research institutes, industrial systems, and the medical industry.
