Milli-DI^® Systems

Milli-DI® Systems Produces deionized water directly from tap water

An Ideal System for Standard Laboratory Needs
The Milli-DI system is a compact and easy-to-use water purification system that instantly provides deionized water (resistivity >1 MW·cm) directly from tap water. Suitable for users requiring low volumes of purified water, 3 to 5 L/day, this battery-powered system comes with everything needed for easy installation in the lab (includes tubing for ½ in. tap fitting).

Operation and maintenance of the Milli-DI system is simple; a green LED light indicates good water quality, and a red LED light indicates that the DI-PAK^® purification pack needs to be replaced. Designed for quick exchange, the DI-PAK purification pack can be easily snapped in and out in seconds without risk of leakage. The pack contains 2.3 L of ion-exchange resin, and can purify 300 L of feedwater (400 µS/cm and 0 ppm of CO₂).
