Laboratory Water Purification Systems

The most popular solvent in any laboratory is water. It is used for everything from cleaning glassware to growing cell cultures to making reagents. As it is used so often, the caliber of water being used is vital to the success of tests.

Whilst tap water may be regarded as relatively pure, there are five groups of contaminants that may pose an issue for laboratory uses: bacteria, gases, inorganic ions, organics, particulates/colloids. Water grades (Types 1-3) help to establish various amounts of water quality for technical and economical purposes. Water quality is established by the technologies used to remove contaminants. Widely used purification solutions include activated carbon, distillation, ion exchange, microporous filters, reverse osmosis, elix continuous deionization, ultrafiltration and ultraviolet (UV) radiation.
