P Water System ver 2, rel 1 30.08.2019
1.5 Operation Principles
VWR P ultrapure water system produces ultrapure water from purified water. Pure water flows
through
H Pack for further deionization, through a UV lamp chamber with a dual wavelength UV
lamp to destroy trace organic pollutants in water, then through a polishing cartridge to remove the
last trace of ions, then a 0.2 μm final filter to the outlet.
