Water is the source of life, and even more the 'yardstick' of precision science. Inside the high-end laboratories of Tsinghua University, the purity of every drop of experimental water is directly related to the nanometer scale of material characterization, the molecular activity of life science, and the trace precision of instrument analysis. For ten years, an AiKe Exceed-Ad-100 series ultrapure water system has taken this as its 'battlefield', silently supporting the precise output of national key research projects with consistently stable 18.25 MΩ·cm ultrapure water and TOC below 3 ppb. From the conventional basic guarantee of RO pure water to the ultimate removal of trace ions by UP ultrapure water, this equipment not only subverts the stereotype of 'domestic equipment not being durable' with its hard-core performance of ten years without water-quality fluctuation, but also becomes an indispensable 'invisible cornerstone' in Tsinghua University's high-level scientific-research water system with extremely low operation and maintenance costs and intelligent consumable management, writing a benchmark case of deep collaboration and long-term empowerment between domestic high-end equipment and a top university.

I. Background of Ultrapure-Water Supporting Use in High-Precision Research Scenarios

This laboratory is located in Tsinghua University, Beijing, and is deeply engaged in high-precision scientific research experiments. It has strict industry standards for the purity and stability of experimental water; water quality directly determines the accuracy and reliability of various precision experimental data. To meet the water needs of high-end research experiments, the laboratory has long been equipped with Exceed-Ad-100 series pure-water equipment; the cumulative use time of the equipment has reached 10 years, and its operation state is stable and mature. The laboratory adopts a dual-level water-supply mode combining RO pure water and UP ultrapure water, graded to meet the water needs of different experimental scenarios.

Among them, RO pure water can meet basic scientific research operations such as conventional utensil cleaning and pre-treatment experiments, while UP ultrapure water is suitable for high-precision research projects such as precision analysis, material R&D, biochemical experiments, and trace detection. Over the past ten years, this water-supply system has continuously provided stable, high-purity experimental-water support for various scientific research projects and topic studies of the laboratory, effectively avoiding the interference of water-quality impurities and ion pollution on experimental results, adapting to the strict requirements of Tsinghua University's high-level scientific research experiments, and ensuring the continuous, standardized, and efficient development of laboratory research work.

II. Ten Years of Stable Operation — AiKe Exceed-Ad-100 Series Ultrapure Water Machine Highly Recognized by Tsinghua University Laboratory

Recently, the multidisciplinary joint laboratory of Tsinghua University in Beijing reported good news about equipment operation: the AiKe Exceed-Ad-100 series dual-water-quality ultrapure water machine has been in stable service at the university for a full 10 years, long providing reliable water support for research scenarios such as material characterization, life-science analysis, and precision instrument testing.

This equipment can simultaneously produce RO pure water and UP ultrapure water, and has consistently maintained the 18.25 MΩ·cm ultrapure-water output indicator for ten years, with TOC persistently below 3 ppb, fully complying with the GB/T 6682-2008 Grade-1 water standard. Relying on modular purification design, intelligent automatic flushing system, and full-lifecycle consumable warning mechanism, the equipment greatly reduces long-term operation and maintenance costs; even under high-frequency continuous water-intake high-intensity use scenarios, it has never experienced water-quality fluctuation problems, laying a solid foundation for the precise data output of many national key research projects of Tsinghua University, and becoming a benchmark case of long-term reliable operation of domestic high-end ultrapure-water equipment.
