Xinrui Laboratory Ultra-Pure Water Purifier
[Product Introduction]
Xinrui ultra-pure water purifiers use tap water as the source and integrate 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 produces pure water that meets the purity requirements for experiments, making it suitable for use in universities, research institutes, industrial systems, and the medical industry.
