Laboratory pure water systems are widely used in research institutes, hospital laboratories, and industrial quality inspection centers to provide high-purity, low-TOC, stable, and reliable experimental water. In molecular biology, they can be used for critical experiments requiring ultrapure water, such as PCR, DNA/RNA extraction, and protein analysis, ensuring the accuracy of results. In analytical chemistry, they are suitable for supplying water to instruments such as HPLC, GC, ICP-MS, and AAS, reducing background interference and improving detection sensitivity. In cell culture and microbiology experiments, they provide sterile, low-ion water for preparing culture media, buffer solutions, and washing glassware. Furthermore, they are suitable for spectral analysis, environmental monitoring, reagent preparation, petrochemical industry laboratories, and all research and testing applications with stringent water quality requirements.
