The core of this case lies in ultra-pure water selection for high-end customs testing laboratories, which comes down to three points: first, hard water-quality indicators must benchmark against Grade 1 standards to keep trace analysis undisturbed; second, the equipment form must match laboratory space and multi-station water needs; third, the supplier must have mature manufacturing capability and a continuous after-sales system. With stable 18.2 MΩ·cm output, compact dual-output design and intelligent O&M, AiKe's Exceed desktop ultra-pure water machine has served China Customs laboratories, verifying the reliability of domestic high-end lab pure-water equipment. With nearly 30 years of technical accumulation and 70,000+ service cases, Tang's Corning AiKe provides one-stop water-treatment guarantees from selection to lifetime maintenance, a trusted choice for laboratory water infrastructure.

🧪 Equipment series: Exceed series
💧 Equipment Water Quality: RO Pure Water + UP Ultrapure Water
The comprehensive technical laboratory of customs undertakes statutory tasks such as import and export commodity inspection, mineral element analysis, and detection of harmful substances in chemicals and food/agricultural products. Such trace analysis has extremely high requirements for experimental water — even trace amounts of ions, organic matter or particulate impurities in water will interfere with the test results of precision instruments such as ICP-MS, atomic absorption and gas chromatography, directly affecting the fairness of commodity qualitative grading and trade clearance. During equipment upgrading, a certain China Customs laboratory, after multiple rounds of comparison and selection, finally adopted AiKe's Exceed series desktop ultra-pure water machine to provide stable water-quality guarantee for test data.
Aiming at the three major characteristics of customs laboratories — 'compact space, harsh water quality, continuous operation' — the Exceed desktop model demonstrates targeted advantages:
Output quality meets Grade 1 water standards. The equipment adopts a five-stage purification process of 'pretreatment + reverse osmosis + ion exchange + UV oxidation + ultrafiltration', with ultra-pure water resistivity stably reaching 18.25 MΩ·cm (25°C) and TOC ≤ 10 ppb, fully meeting the GB/T 6682-2008 Grade 1 water standard and international standards such as ASTM and CLSI, capable of handling high-end applications such as trace element analysis and standard solution preparation.
Desktop design fits the laboratory layout. The compact body can be placed directly on the laboratory bench without a dedicated machine room; the dual-output design simultaneously supplies RO pure water and UP ultra-pure water, meeting the needs of vessel cleaning and instrument injection respectively, with one device covering the entire laboratory's water scenarios.
Intelligent monitoring reduces O&M burden. Functions such as online conductivity/resistivity real-time display, consumable-life reminders, water-shortage protection and automatic RO membrane flushing ensure stable unattended operation for long periods, fitting the continuous-operation rhythm of customs laboratories.
After the equipment was put into use, the online water-quality monitoring data remained stable over the long term, providing a reliable water foundation for the laboratory's element analysis and physical/chemical testing. Coupled with the manufacturer's regular on-site inspections, consumable replacement and system calibration, the instrument failure rate and test retest rate dropped significantly, and the laboratory gave positive evaluations of the equipment's operating status.
The success of this cooperation is inseparable from the professional water-treatment enterprise behind it — Sichuan Chengdu Tang's Corning AiKe Water Purifier Co., Ltd. The company has nearly 30 years of water-treatment technical heritage, with 70,000+ customer cases and 110+ qualifications and patents, integrating R&D, manufacturing, sales and service of wastewater treatment equipment.
