Product Overview
The Barnstead EASYpure R
O
D
I
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 osmo-
sis 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 fil-
ter.
The % rejection between incoming and reverse osmosis prod-
uct 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 R
O
D
I
ʼs self-contained 6.5-liter
reservoir as determined via the position of 3 floats in the
reservoir.
The EASYpure R
O
D
I
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 using part number D502132.
The EASYpure R
O
D
I
is designed to be a bench mounted unit.
If wall mounting is required, refer to “Locating the Unit” on
