Model 2121AU Analytical Grade Type I DI System
Designed for applications that require up to 50 Liters/day of General or Analytical Grade Type I Ultra Pure water.
Produces 2-3 Liters/minute of 18.2 Megohm.cm Type I water from feed water that has been pretreated via reverse osmosis and/or ion exchange and contains less than 20 PPM of total dissolved solids.
Includes a Built-in UV Sterilizer.
The AQUA SOLUTIONS' Model 2121AU is also available in a High Flow/Capacity (4-10 Liters/Min) version. These lab water purification systems are semi-custom designed for each application. Contact your salesperson for more information.
This unit operates on pretreated water, for operation on Ordinary Tap Water see: Model 2122A or Model 2122AU.
They are also available with built-in reverse osmosis pretreatment, in a single cabinet design measuring just 20" wide x 20" high x 12" deep: Model RODI-C-12A or Model RODI-C-12AU.
Note: High Flow/Capacity Systems are not available for export.
All AQUA SOLUTIONS' Analytical Grade Type I DI Systems produce purified water that meets or exceeds ASTM, CAP and NCCLS specifications for Type I reagent grade water.
