Introduction to DUO™ II.I Water Purification System

The DUO™ II.I Water Purification System combines the trusted purifying technology of the GENO™ II with the impressive flexibility of the ALTO™ I. It processes potable water to Type 2 for the storage reservoir, which can be used for general laboratory applications or for dispensing Type 1 water as needed.

Key Features of the DUO™ II.I Water Purification System

The DUO™ II.I Water Purification System is a complete pre-engineered system designed to provide Type 2 water that can be dispensed from the storage tank via a dispensing tap or Type 1 water that can be dispensed from an integral dispenser gun or via a remote dispenser gun. The innovative and unique DUO™ II.I Water Purification System provides two water qualities within one easy-to-use system. Save on space, initial outlay and consumable costs.
