Introduction to lab water deionizer
Laboratory deionizer is an important equipment used in laboratories to remove ion impurities from water. Deionized water is usually prepared through ion exchange technology, which uses cation and anion resins to remove ion impurities from water.The common applications of laboratory deionized water equipment include providing high-purity deionized water to meet various experimental needs. For example, the laboratory requires the use of deionized water for mass spectrometry analysis, liquid chromatography, molecular biology, and ultra trace analysis. In addition, deionized water equipment can further improve water quality through various methods such as reverse osmosis and ultraviolet sterilization.

Use of lab water deionizer
The common applications of laboratory deionized water equipment include providing high-purity deionized water to meet various experimental needs. For example, the laboratory requires the use of deionized water for mass spectrometry analysis, liquid chromatography, molecular biology. And ultra trace analysis. In addition, deionized water equipment can further improve water quality through various methods such as reverse osmosis and ultraviolet sterilization.
The resistivity of deionized water is typically around 18 megaohm centimeters (M Ω – cm). Making it an ideal choice for high-precision measurement and analysis in laboratories. Laboratory deionized water systems typically include filtration units, cation beds, anion beds. And mixed bed ion exchange resin tanks, sometimes equipped with activated carbon tanks to remove organic pollutants.
