RiOs-DI Water Purification Systems

Produce up to 15 L daily of high quality analytical grade water (Type 2 water) from tap

Superior quality pure water and easy maintenance

RiOs-DI systems provide users with a compact solution that efficiently combines reverse osmosis technology with deionization resins to produce high quality pure water with high resistivity and low TOC (> 10 MΩ•cm and < 30 ppb). Water produced by the systems is superior to that of service DI or stills, and users have none of the maintenance, storage and cleaning issues associated with these other purification methods. The system’s product water is stored in an internal reservoir, and is ideal for low volume laboratory applications.

The unique, simple “plug-and-use” purification pack enables the production of high quality (Type 2) water from tap water. To ensure reliable contaminant removal, the system’s pump will continue to send a steady flow of tap water to the cartridge, in spite of low pressure on the supply side or a drop in water temperature.


  • Buffer and reagent preparation
  • Microbiological culture media preparation
  • General washing


  • Combining several purification technologies including Reverse Osmosis and Deionization, RiOs-DI systems remove all types of water contaminants (typically > 99 %).
  • The built-in 254 nm UV lamp* is ideal for applications that require low bacteria levels.
  • The consumable is a unique “all-in-one” pack that includes the pretreatment, reverse osmosis membrane and ion-exchange resin.
  • Maintenance is reduced to the quick change of a single cartridge.
  • Backlit color display shows resistivity and temperature values, water level in reservoir, and alarms if necessary.
  • Integrated, compact 6-liter reservoir.

* This system is also available without a UV lamp.
