Milli-DI® Laboratory Water Purification System
The Milli-DI system is a compact and easy-to-use lab water purification system that instantly provides deionized water (resistivity >1 MΩ·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" 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).
Good Practices in Using a Water Purification System and Handling High Purity Water
The usage of water purification systems is widespread in laboratories. This scientific poster describes a number of “good laboratory practices” for working with high purity water. The importance of rinsing newly installed RO cartridges is analysed by measuring TOC levels in a water sample. Reservoir material for longer-term water storage, regular monitoring of water quality and flushing the water system are also discussed as part of good lab practice.
