WaterPro PS Polishing Stations deliver Type I, 18.2 megohm-cm water from the dispensing valve or optional dispensing gun at a typical rate of 1.8 liters per minute depending on feedwater flow rate and pressure, and installed purification modules. The control panel includes a timed dispense feature that allows unattended dispensing of pure water without risk of overfilling. The dispenser shuts off automatically once user-set time has elapsed. Labconco has designed WaterPro PS Stations with the right combinations of purification technologies to meet your needs. Choose from specialized stations for general chemistry, analytical, life science or combination usage. In addition, models designed for general chemistry may be upgraded with additional purification modules at a later time for use in analytical or life science applications.
