what is laboratory water deionizer
Our laboratory deionized water machine is a device specifically designed for preparing high-purity deionized water, widely used in industries such as pharmaceuticals, electronics, chemical engineering, and biophysical laboratories. Its main function is to remove impurities and ions from water through a series of physical and chemical methods to ensure that the water quality meets experimental requirements.
Our laboratory water deionizer can effectively remove all solid impurities, salt ions, bacteria and viruses from water. Thus producing high-quality deionized water. For example, some devices can display the UP ultra pure water resistivity and RO pure water conductivity online, and monitor water quality in real time.

Process of laboratory water deionizer
Filtration: Using a multi-stage filtration system to remove large particulate impurities and suspended solids from water.
Reverse osmosis (RO): Separation of most dissolved solids, bacteria, viruses, and other substances in water through a semi permeable membrane.
Ion exchanger: removes hardness ions such as calcium and magnesium. As well as other soluble ions from water through cation and anion exchange resins.
UV sterilization: using ultraviolet light to disinfect water to eliminate microbial contamination
