Using advanced reverse osmosis technology and ultra-purification column with original formula filler, Okay energy ultra-pure water and reverse osmosis RO pure water machine provides the overall solution of laboratory water. This series of machine use tap water as water. At the same time, the preparation of 18.2 MOhm-cm ultrapure water and RO pure water, ultrapure water reach or exceed the quality standards of China laboratory water and test methods(GB6682-2008)and ASTM, CLSI, ISO3696 level of water quality standards. This system is compact and easy to operate.
