Specially formulated to prevent bacterial growth, organic contaminants, and corrosion within humidified incubators: After years of feedback and study, INFORS HT has developed Water for Incubators. It is double distilled, 0.1um filter sterilized, has a pH of 7-9 with a conductivity of 1-20 microSiemens (Resistivity of 50K-1 M ohm), and is terminal sterilized. The water formulation removes certain divalent ions and raises the pH to fight off waterborne bacteria and fungi to provide a sterile culture environment.
