Ultrapure water is deionized water in which non-ionic, colloidal, bacterial, virus and organic matter suspended particles are removed during the production process using an advanced filtration system. This water is widely used as a solvent for HPLC devices in pharmaceutical and medical industries, scientific and research laboratories, food quality control laboratories and petrochemical industries. Ultrapure water is also used to measure toxic metals at very low concentrations with ICP_MS and graphite furnace (GFAAS) atomic absorption devices.In this regard, in order to produce this product, there was a need to purchase a deionizer device in line with the double RO process. This handle with a 0.2 micron filter is not allowed to pass any particles above this value. On the other hand, due to the use of rainwater as an alternative source of input to this device, the water produced is of high quality and has the ability to compete with imported products. North Rain Sky Springs Company is proud to produce ultra-pure rainwater since 1398 and to offer this product with high quality in 1 and 2.5 liter glass containers in many laboratory centers in the country.
