Seven years is enough for a frontier technology to iterate through several rounds, and enough to verify whether a set of equipment can withstand the tempering of time.

At the School of Chemistry, Central China Normal University, an AiKe Advanced-IV series ultrapure water machine has been running silently for seven years. From inorganic synthesis to organic analysis, from undergraduate teaching experiments to cutting-edge research, this equipment has witnessed the birth of countless academic achievements and endured the sustained test of high-frequency, high-intensity, multi-scenario water intake in university laboratories. For the discipline of chemistry, ultrapure water is the 'invisible reagent' running through daily teaching and in-depth research—once water quality becomes unstable, chromatographic peak drift, elevated blank values, and reduced reaction reproducibility all add variables to the research process.

Over the seven years, this equipment has always maintained stable ultrapure-water output at 18.25 MΩ·cm and has never experienced a major operational failure. With a service life far exceeding similar equipment and consistently unchanged outlet-water quality, it proves a simple truth: the most precious quality of a laboratory pure-water system is not the peak numbers on the parameter sheet, but the stable companionship that remains reliable year after year.

I. Seven Years of Deep Cultivation in Research and Teaching — Stable Pure-Water System Empowers Chemistry Experiments

The School of Chemistry, Central China Normal University is located in Wuhan, Hubei, and is the core base for university chemical research and talent cultivation. It has long undertaken teaching experiments, project research, and precision testing in many fields such as inorganic chemistry, organic chemistry, analytical chemistry, and materials chemistry. Various high-precision experiments, trace reagent preparation, and instrument analysis testing impose extremely high requirements on the purity and stability of experimental water quality; water-quality impurities and substandard purity will directly cause experimental data deviation and poor experimental reproducibility, seriously affecting research progress and teaching quality.

To meet the university's diversified and high-standard laboratory water needs, the School introduced the AiKe Advanced-IV series ultrapure water machine, equipped with RO pure water + UP ultrapure water dual-output mode, covering full-scenario water needs such as basic utensil cleaning, routine experiments, and high-precision research experiments. The equipment has served stably in the School's laboratories for 7 years, long adapted to the high-frequency, high-intensity experimental-water conditions of universities, with continuously compliant outlet-water quality, low operational failure rate, and convenient maintenance—perfectly adapting to the normalized research and teaching work of the School of Chemistry, and building a stable, quality water assurance for various chemical experiments and project research.

II. AiKe Advanced-IV Series Ultrapure Water Machine Safeguards the Research Water of the School of Chemistry, Central China Normal University

Recently, the AiKe after-sales team completed the annual inspection of the ultrapure-water equipment at the School of Chemistry, Central China Normal University. The Advanced-IV series ultrapure water machine that has been running continuously and stably for 7 years still maintains stable outlet-water quality, providing reliable support for various chemical analyses and fine-synthesis experiments of the School.

The School of Chemistry, Central China Normal University has long carried out research and teaching in organic chemistry, analytical chemistry, environmental chemistry and other directions, requiring large amounts of RO pure water and UP ultrapure water that meet Grade-1 standards daily to ensure data accuracy of precision experiments such as chromatographic analysis and element detection.

This Advanced-IV series equipment has been in place since 2019, adapted to Wuhan's local incoming-water quality, relying on DOW (USA) RO reverse-osmosis membranes and a full-process intelligent monitoring system to stably produce ultrapure water with resistivity 18.25 MΩ·cm over the long term, with no major operational failures throughout. Over the 7 years, the equipment's consumable-replacement cycle has always met the design standard, and its maintenance cost is far lower than similar traditional equipment; with solid long-term operation performance, it has become a benchmark case of long-term stable operation of ultrapure-water equipment in university chemistry laboratories.
