Millipore Corporation has developed an economical laboratory water purification system that can accommodate all purified water needs. The easy-to-use RiOs-DI 3 UV system is optimal for low volume, routine laboratory applications ranging from buffer, reagent and culture media preparation to general washing. The high quality product water (>10 MΩ·cm and less than 50 ppb TOC) is ideal for feeding ultrapure water systems (i.e. Milli-Q or Synergy systems). Additionally, the RiOs-DI 3 UV system has a built-in 254 nm UV lamp, which ensures low bacterial levels in the water produced for sensitive applications. The easy-to-maintain RiOs-DI 3 UV system combines all major purification technologies into a single disposable pack. The innovative cartridge design simplifies the maintenance process. Additionally, the clear graphic display indicates system parameters and water quality so that it is clear when the cartridge need to be changed. Not only does this save time, but it als improves overall efficiency without compromising results.
