Precision research puts water quality first; the purity and stability of experimental water is the core foundation for measuring the accuracy of research data and ensuring the smooth progress of frontier research. As a top domestic institution of higher learning, Peking University is deeply engaged in multiple frontier fields such as materials science, life science, and precision analysis; various high-precision experiments in its national key laboratories have strict standardized requirements for experimental water quality. Problems such as water-quality fluctuation and cumbersome operation and maintenance of traditional water-supply equipment once constrained the development of refined scientific research. In September 2024, Peking University officially introduced and put into use the AiKe Advanced-III series laboratory ultrapure water machine.

After two years of normalized high-frequency operation, relying on core advantages such as integrated dual-water supply, intelligent operation and maintenance, and excellent water-quality stability, the equipment perfectly adapts to the diversified scientific-research water-use scenarios of universities. The equipment can simultaneously produce RO pure water and UP ultrapure water, with water quality far exceeding the national Grade-1 water standard, and stable operation with zero failures throughout, building a solid water-quality foundation for nearly a hundred national-level research projects, and becoming a high-quality benchmark case for the localized application of high-end pure-water equipment in university laboratories.

I. PKU Adds Another Research Heavyweight: AiKe Advanced Series Ultrapure Water Machine Settles in Yanyuan, Two-Year Operation Highly Praised by the Laboratory

In September 2024, the School of Materials Science and Engineering of Peking University welcomed a special 'experimental partner'—an AiKe Advanced series laboratory ultrapure water machine was officially installed and put into use. Two years later, with its consistently stable and excellent performance, this equipment has become the 'low-key behind-the-scenes contributor' in the mouths of teachers and students on the research front line.

As a top domestic institution, Peking University has near-exacting requirements for experimental water purity in frontier research such as material synthesis, precision analysis, and life science. The AiKe Advanced series ultrapure water machine adopts a dual-level water-supply mode of RO pure water + UP ultrapure water, one machine with two uses, simultaneously meeting the water needs of different scenarios from conventional utensil cleaning to ICP-MS trace analysis and cell culture. The equipment's produced-water resistivity stably reaches 18.25 MΩ·cm, and the water quality is better than the GB/T 6682-2008 Grade-1 standard throughout, effectively eliminating the interference of impurity ions with experimental data. Relying on its systematic functions such as intelligent water-quality detection, fault warning, and consumable-replacement reminders-, this equipment has always maintained zero-failure operation during two years of high-frequency water intake, providing solid water-quality assurance for the smooth progress of many research topics at Peking University, once again confirming the reliable quality of AiKe's domestic ultrapure-water equipment.

II. Adapting to Top-Tier Research Needs — AiKe Advanced-III Series Safeguards PKU's Dual-Water Supply for Two Years

Peking University covers dozens of key disciplines such as mathematics, physics and chemistry, life science, and frontier engineering; multiple national key laboratories on campus carry out core research work such as high-precision trace analysis, cell culture, and mass-spectrometry detection all year round. The stability of experimental water directly determines data accuracy and is an indispensable basic guarantee in the research chain.

Previously, some old water-supply equipment on campus had pain points such as slow dual-water switching response and large water-quality fluctuations. After introducing the AiKe Advanced-III series ultrapure water machine in 2024, the equipment can simultaneously and stably produce RO pure water and UP ultrapure water, with produced-water resistivity stably above 18.2 MΩ·cm for a long time, fully matching the GB/T 6682 Grade-1 water requirement.

After two full years of operation, the equipment has adapted to the high-frequency, large-flow water-use scenarios of the laboratory; the intelligent monitoring system can give real-time warnings of consumable loss, and the operation-and-maintenance response efficiency has improved by 40%. It has cumulatively supported nearly a hundred national key research projects to progress smoothly, and with the advantages of low failure rate and low operation-and-maintenance cost, it has become a benchmark sample among the newly purchased equipment in the PKU laboratory.
