Purite Labwater Deionisers

Type II / Deionised (DI) water

The Purite Labwater is a simple, cost-effective option for producing low volumes of purified water between 1 and 10μS/cm on-demand.  

Purite Labwater units can easily be wall-mounted and are simply connected by a conventional hose to a laboratory tap. They operate under standard water pressure, so no additional parts are required. 

The Purite Labwater uses a special resin which absorbs ionic contaminants. As the resin becomes saturated its colour changes from blue to brown to indicate when a replacement is required.

Purite Labwater | Overview

The Purite Labwater dionisation unit produces low volumes of purified water between 1 and 10μS/cm on demand, from a standard laboratory water supply. Connection to a tap or stock-cock is via a simple flexible hose. Fitting is quick and simple.

The colour-change resin indicates when replacement is required. Two versions are available, for flow rates of up to 60 l/hour. Output capacity will vary depending on water hardness; typically, capacity will be up to 1280l for soft water regions.
