Application Area:

Ultra pure water for sensitive chemical reactions

We have this device in our laboratory since 2016 and are satisfied with its performance. It does what it is supposed to - it produces ultra pure water which can be used in applications sensitive to the lowest concentration of contaminates. The tap water in our location contains high amounts of iron but this water purification system does an excellent job in removing it. The customer support is fast and helpful. We usually receive a reply within 24 hours.
