3 types of water for every application in your lab

Ultrapure Water for analytical applications such as HPLC, cell culture, tissue culture or molecular biology techniques.

Pure Water for applications including general reagent preparation, buffers, pH solutions, histology and general chemistry.

 RO – permeate water for glassware rinsing, water baths, autoclaves, hydroponics and as feed water to Type 1 systems.
