The Norgen water purification system has been designed in conjunction with experts from Millipore Sigma. The Ultrapure NFW is purified in a two-stage process. The first stage, to produce type II water, includes pre-treatment with activated charcoal and polyphosphate, this water then undergoes reverse osmosis, electro-deionization and ion exchange to remove contaminants as well as UV treatment for disinfection. The Pure water then flows to a second system in a clean room with an additional 4 layers of purification. After passing through an additional ion exchange column, the water is then subjected to Ultrafiltration to remove particulates, bacteria, & ionic contaminants down to trace level, the water is then treated with UV light (182 nm wavelength) to break down organic matter. Lastly a second Ultrafilter for the production of pyrogen-, nuclease- and bacteria-free water at 18.2 MΩ. This water is of utmost purity and suitable for direct use in molecular biology applications such as qPCR and NGS, as well as cell culture and other applications.
