The EUE-10/20UV Low TOC EDI Type I Ultrapure Water System is designed for laboratories requiring ultrapure water with exceptionally low organic contamination levels. By integrating Reverse Osmosis (RO), advanced Electrodeionization (EDI), final polishing purification and dual-wavelength UV oxidation technology (185/254 nm), the system delivers Type I ultrapure water with resistivity up to 18.2 MΩ*cm and Total Organic Carbon (TOC) levels as low as 2 ppb.

Modern chromatographic and mass spectrometry instruments are highly sensitive to trace organic contaminants. Even low levels of organic compounds can affect baseline stability, peak resolution and analytical reproducibility. The integrated UV oxidation module continuously breaks down organic molecules and helps maintain consistently low TOC levels, making the system suitable for demanding analytical workflows.

Unlike conventional ion-exchange systems, EDI technology continuously removes ionic contaminants through an electrically driven purification process, helping to maintain stable water quality while reducing reliance on frequent cartridge regeneration or replacement. This contributes to lower operating costs and improved long-term system efficiency.

The EUE-10/20UV operates directly from municipal tap water, simplifying installation while delivering reliable ultrapure water quality. Integrated monitoring sensors continuously track feed water, EDI water and ultrapure water quality, ensuring dependable system performance.

A user-friendly 5-inch color touchscreen provides real-time access to water quality parameters, operating status, alarm notifications and consumable information. The intelligent control platform supports laboratory quality management and traceability requirements.

Equipped with a high-capacity PE storage tank, the system ensures a stable supply of water for daily laboratory operations. Its advanced purification technology makes it an ideal solution for pharmaceutical laboratories, research institutes, analytical testing centers and industrial quality control laboratories.
