Type II Water System 2-1Thermo Scientific
Section 2 Product Information
The Barnstead TII is a tap-fed water purification system designed to be
simple to use and to provide reagent-grade water that exceeds ASTM Type
II, and CLSI®-CLRW standards. It uses a thin film composite reverse
osmosis membrane with 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 % of 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. Pressure sensors located inside the unit
monitor incoming feed water and RO pressure. The DI water purity is
continuously measured by a resistivity cell and displayed on a
multifunctional display.
RO operation is automatic and works independently of the DI system to
fill the external reservoir as determined by sensors in the reservoir.
Read the instructions carefully to ensure that you receive maximum benefit
from the Barnstead TII. Also, please fill out and return the enclosed
warranty registration card, as it will help us assure you of proper warranty
coverage.
Note The Barnstead TII is not shipped with pretreatment and DI
polishing cartridges or a final filter. These must be ordered separately. The
start-up kit containing these components can be ordered using part
number D502138 for all units.
