WaterPro PS Polishing Systems – General Chemistry Models
The WaterPro PS General Chemistry Polishing Systems deliver Type I water, up to 18.2 megohm-cm, from the dispensing valve or optional dispensing gun at a typical rate of 1.8 liters per minute. These systems combine carbon filtration and deionization technologies to produce high-purity water suitable for atomic absorption, flame emission spectroscopy, trace metal analysis, buffer solutions, and standard reagent solutions.

Dispensing Options
Dispensing Valve Models: Include a dispensing valve located on the dispensing center. Water delivery is controlled by pressing the DISPENSE switch on the control panel or by activating the timed dispense feature.
Dispensing Gun Models: Include a dispensing gun that rests in the dispensing center and is attached to a 3-foot flexible recirculating line. The gun delivers Type I water by depressing the trigger. A dispensing valve located on the polishing system provides additional dispensing control via the DISPENSE switch or timed dispense feature.
Control Panel Functions
The control panel includes an ON/OFF switch, LED display, indicator lights for MEG Ω, TEMP °C, TIME DISP., and SET PT., a DISPENSE switch, MODE switch, and increase/decrease controls. The LED display shows actual water quality in megohm-cm, actual water temperature in °C, or water quality set point in megohm-cm. The display flashes when quality drops below the user-selected set point.
