Introduction

Section 2
The Barnstead EASYpure RODI is a tap-fed water purification system
designed to be simple to use and to provide reagent grade water that
exceeds ASTM, Type I, and NCCLS/CAP Type I standards. It uses a thin
film composite reverse osmosis membrane with one stage of pretreatment
to produce RO water that is then polished using a two-stage deionization
process combined with UV oxidation and a 0.2 micron final filter.
The % rejection between incoming and reverse osmosis product water is
monitored and an indication is provided to the user if the RO water
quality is unacceptable. RO membrane pressure is provided by a pressure
gauge located on the right side of the unit. The DI water resistivity is
continuously sensed by a resistivity cell and displayed on a digital display
in megohms-cm.
RO operation is automatic and works independently of the DI system to
fill the EASYpure RODIʼs self-contained 6.5-liter reservoir as determined
via the position of 3 floats in the reservoir.
The EASYpure RODI is not shipped with a reverse osmosis membrane,
cartridges or final filter. These must be ordered separately. The start-up kit
containing these components can be ordered from Technical Services.
The EASYpure RODI is designed to be a bench mounted unit. If wall
mounting is required, refer to "Wall Mounting" on Section 5.
