Brief Introduction to ultra pure water system laboratory
The laboratory ultrapure water system is a device specifically designed for preparing high-purity water, widely used in laboratories such as medical, health, drug testing, pharmaceutical universities, and research institutes. These systems remove impurities, ions, microorganisms, etc. from water through multi-level purification technology, thereby producing high-purity and sterile water.
The working principle of a laboratory ultrapure water system usually includes the following steps: pretreatment unit, reverse osmosis module, ion exchange resin filter, ultraviolet sterilizer, etc. Specifically, the pre-treatment unit is mainly used to remove large particle impurities and suspended solids. While the reverse osmosis module further removes dissolved salts and organic matter. Finally, the water quality is ensured to achieve extremely high purity through steps such as ion exchange and ultraviolet sterilization.
The water quality standards for laboratory ultrapure water systems usually comply with the Class I water standards of the Chinese National Laboratory Water Specification GB6682-2008, as well as the American ASTM, NCCLS, and CAP reagent grade pure water standards. For example, the resistivity can reach 18.2 M Ω • cm@25 ℃
Our laboratory’s ultra pure water system not only needs to meet the requirements of high purity. But also needs to have stability and reliability to ensure the accuracy and repeatability of laboratory experiments. These systems usually adopt a combination of advanced reverse osmosis technology and ion exchange technology. And are controlled by microcomputer single board computer programs to achieve fully automatic operation.
The laboratory ultrapure water system is an indispensable and important equipment in the laboratory. It ensures the provision of high-quality ultrapure water through complex physical and chemical processes. It meet the needs of various high-precision experiments.
