In the world of precision science, water purity is the first gate of experimental accuracy. For Beijing Institute of Technology, a national key university deeply rooted in military heritage and known for frontier exploration in science and engineering, the quality of every drop of experimental water directly affects the microscopic characterization of material properties, the precise qualification of trace substances, and the repeatability verification of frontier biochemical reactions. Twelve years, a complete cycle of a research period—an AiKe Advanced-III series ultrapure water machine stands quietly in a corner of the laboratory, silently supporting research tasks across multiple levels, from undergraduate teaching experiments to key projects of the National Natural Science Foundation, with consistently stable water output.

From RO pure water guaranteeing basic utensil cleaning and routine solution preparation, to UP ultrapure water serving high-precision scenarios such as ICP-MS trace analysis, protein purification, and cell culture with ultimate resistivity of 18.25 MΩ·cm and TOC as low as 1-5 ppb, this two-stage water-supply system has gone through twelve years of cold and heat, with daily high-frequency water intake yet zero water-quality fluctuation, cumulatively escorting nearly a hundred national-level research projects to smooth progress. In August 2026, the annual inspection results of the AiKe technical service team showed that this equipment, in service for over ten years, still matches a new machine in all performance indicators after core-filter calibration, sterile pipeline disinfection, and intelligent system upgrade. This is not only a powerful demonstration of the reliability of domestic ultrapure-water equipment, but also a vivid footnote of deep collaboration and long-term empowerment of scientific-research innovation between Chinese intelligent manufacturing and top science-and-engineering universities.

I. Application Background of the Ultrapure-Water System in the Beijing Institute of Technology Laboratory

This Advanced-III series pure-water equipment serves the Beijing campus laboratory of Beijing Institute of Technology, with a cumulative stable use time of 12 years; it is the core water-supply equipment for the laboratory's scientific research experiments, sample testing, and instrument operation and maintenance. Beijing Institute of Technology is deeply engaged in frontier scientific-research and teaching experiments in science and engineering; various precision experiments have extremely high requirements for water-quality purity and stability, and ordinary tap water cannot meet high-precision research needs.

The laboratory adopts a dual-level water-supply mode of RO pure water + UP ultrapure water, graded to adapt to different experimental scenarios. Among them, RO pure water can meet the needs of conventional utensil cleaning and basic pre-treatment experiments, while UP ultrapure water has higher purity, suitable for high-precision research projects such as precision instrument analysis, material synthesis, biochemical experiments, and trace detection. Over the years, the equipment has continuously delivered stable compliant water quality, effectively avoiding the problem of impurities and ions interfering with experimental data. Relying on the equipment's long-term reliable operation performance, it has provided solid water-quality assurance for various scientific research topics, teaching experiments, and innovation projects on campus, supporting the normalized and high-quality development of all research work in the laboratory.

II. AiKe Advanced-III Series Ultrapure Water Machine Safeguards the BIT Research Front Line — 12 Years of Stable Operation Builds the Water Foundation

In August 2026, the AiKe technical service team went to the Beijing Institute of Technology laboratory and completed the annual special inspection and maintenance of the Advanced-III series ultrapure water machine that had been in continuous service for 12 years. This equipment, rooted in the research front line for a long time, has always stably produced RO pure water and UP ultrapure water, providing solid water-quality assurance for core research scenarios such as advanced material R&D and precision instrument analysis on campus.

As a strong domestic engineering school, Beijing Institute of Technology has strict requirements for experimental water purity; from high-precision spectrum detection to trace-element analysis, the accuracy of every experimental data depends on stable ultrapure-water support. During the 12 years of operation of this Advanced-III series equipment, the produced-water resistivity has always been stably up to standard, fully meeting the GB/T 6682 Grade-1 water standard throughout; relying on AiKe's full-lifecycle operation and maintenance system, the equipment's failure rate is far below the industry average, greatly reducing the laboratory's long-term operation and maintenance costs.

During this inspection, the technical team completed full-process maintenance such as core-filter performance calibration, sterile pipeline disinfection, and intelligent control system upgrade, keeping this equipment, in service for over ten years, still in excellent operating condition. Up to now, the equipment has cumulatively supported nearly a hundred national-level research projects, becoming the 'reliable old partner' in the mouths of many researchers on campus, and also confirming the long-term stable hard-core quality of AiKe ultrapure water machines.
