The Crystal Bio and Integrity+ Bio systems produce ultrapure water right from tap water. Water is purified in two stages: pure water is produced first and stored in the tank. Pure water is later used for production of ultrapure water, used for highly sensitive biological and chemical applications like flow cytometry, cell and tissue culture and molecular biology.

Grade 1 water produced by these systems complies with ISO 3696, ASTM and CLSI standards.
