The Labconco WaterPro PS Polishing Systems have been specifically designed to meet the
ultrapure water needs in a variety of laboratory applications.
The most basic of WaterPro PS models, General Chemistry, is ideally suited for typical chemical
research labs. The WaterPro PS/HPLC models are specifically designed for demanding analytical
chemistry work, involving sensitive instrumentation and requiring the lowest levels of Total
Organic Carbon (TOC). The WaterPro PS/UF models are suited for bio-analytical research,
requiring bacteria and/or pyrogen-free water.
Prepurified water of a minimum purity of 100µs or better is plumbed to the WaterPro PS through a
3/8" feedwater supply line. The built-in regulator allows the unit to accept water pressure from 0-
100 psi. The feed water must flow at a rate of 2 liters/minute or greater at the given inlet pressure.
The General Chemistry model purifies the water to Type I quality through the use of carbon and
deionization resins and provides a typical flow rate of 1.8 liters/minute. The HPLC models allow
for the addition of an organic adsorption cartridge and include a dual wavelength ultraviolet
reactor to oxidize last traces of organic compounds ensuring ultra low levels of total organic
carbon. The Life Science models provide Type I water free of bacteria and pyrogens through the
use of an ultrafilter and germicidal ultraviolet reactor. The HPLC/Hybrid models not only give
HPLC quality water through the use of the ultraviolet reactor, but deliver low level bacteria and
pyrogen-free water.
Each model has the capability of displaying water quality, water temperature, low resistance set
point and a programmable time dispense mode. Each model is offered with a dispensing valve,
with or without a dispensing gun. Figure 1 shows models with dispensing gun and with dispensing
valve only. A 0.2 micron self-venting hollow fiber final filter can be added to the gun or valve as
an accessory when required. Ultrafilters and optional 0.2 micron final filters will reduce pure water
flow rates.
