Overview
The HePu EU-T Ultra-Pure Water System is an integrated laboratory-grade water purification platform engineered for consistent production of Type I ultrapure water per GB/T 6682–2008 and aligned with ASTM D1193–2020 Type I specifications. It employs a multi-stage purification architecture combining pre-filtration, dual-stage reverse osmosis (RO), electrodeionization (EDI) or mixed-bed deionization (depending on configuration), and final 0.1 µm ultrafiltration with optional UV oxidation (185/254 nm). The system is specifically designed to serve as primary feedwater for sensitive analytical instrumentation—including HPLC, IC, AFS, GC-MS, ICP-MS—and as critical process water for cell culture, molecular biology, and diagnostic platforms requiring endotoxin-free, low-TOC, particle-controlled output. Its closed-loop distribution design minimizes recontamination risk while maintaining stable resistivity ≥18.2 MΩ·cm at 25 °C under continuous operation.
Key Features
- Microprocessor-controlled operation with capacitive touch interface and real-time LCD display featuring backlighting for ambient-lit lab environments
- Online resistivity and TOC monitoring with automatic data logging and configurable alarm thresholds for consumables (RO membrane, UP cartridge, UV lamp)
- Programmable auto-flush cycle for RO membranes—adjustable frequency and duration to extend membrane service life and maintain salt rejection stability
- Comprehensive safety architecture: dry-run protection, low-inlet-pressure warning, overpressure cutoff, full-tank shutoff, and leak detection circuitry
- DOW FilmTec™ RO membranes (original import) delivering ≥98% salt rejection and validated performance across variable municipal feed profiles
- Non-pressurized, constant-pressure delivery system compatible with all major brands of clinical analyzers (e.g., Roche Cobas, Beckman AU, Siemens ADVIA) without need for external booster pumps
- Modular quick-connect fluidic layout enabling tool-free replacement of filters, cartridges, and UV modules—reducing mean time to repair (MTTR)
- GLP-compliant chassis constructed from ABS polymer and electrophoretically coated steel with reinforced insulation, IP22-rated enclosure, and Class II electrical safety certification
Sample Compatibility & Compliance
The EU-T system delivers water meeting or exceeding the stringent requirements for Type I reagent water in ISO 3696:1987, CLSI EP22-A2, and USP . Its output supports applications demanding ultra-low endotoxin (<0.001 EU/mL), sub-ppt heavy metal content, and particulate control down to 0.1 µm. All wetted materials—including tubing, housings, and sensors—are certified non-leaching and compliant with FDA 21 CFR 177.2600 for repeated contact with aqueous solutions. System validation documentation includes IQ/OQ templates aligned with GLP and GMP Annex 15 expectations. Calibration certificates traceable to NIM (National Institute of Metrology, China) are available upon request.
Software & Data Management
The embedded controller records operational parameters—including date/time-stamped resistivity, TOC, pressure differentials, flow rates, and maintenance events—for up to 12 months. Data export is supported via USB 2.0 (CSV format) for integration into LIMS or electronic lab notebooks. Audit trail functionality complies with FDA 21 CFR Part 11 requirements when paired with user-defined role-based access control (optional firmware upgrade). Remote status monitoring is achievable through optional RS485 Modbus RTU interface for centralized facility management systems.
Applications
- HPLC and UHPLC mobile phase preparation and column equilibration

- PCR master mix preparation and next-generation sequencing library construction
- Automated clinical analyzers (chemistry, immunoassay, hematology) requiring stable, low-conductivity feedwater
- Atomic fluorescence spectrometry (AFS) and graphite furnace AAS calibration
- Electrophysiology buffer preparation and patch-clamp recording solutions
FAQ
What standards does the EU-T system meet for ultrapure water quality?
It conforms to GB/T 6682–2008 Grade I, ASTM D1193–2020 Type I, and ISO 3696:1987 Type I specifications—including resistivity ≥18.2 MΩ·cm, TOC ≤3 ppb, bacteria ≤0.001 CFU/mL, and particles ≤1/mL (>0.1 µm).
Is the system suitable for use in regulated pharmaceutical QC labs?
Yes—when configured with audit trail-enabled firmware and operated under documented SOPs, it supports compliance with GLP, GMP, and 21 CFR Part 11 requirements.
How often must the RO membrane be replaced?
Typical service life is 2–3 years under municipal feed conditions; the system triggers visual and audible alerts based on cumulative operating hours and pressure differential drift.
Can the EU-T supply multiple instruments simultaneously?
Yes—benchtop models support distributed feed via passive manifold or active recirculation loop (optional); flow rate stability is maintained within ±5% across 1–4 simultaneous outlets.
Does the system include validation support documentation?
Standard delivery includes Factory Acceptance Test (FAT) report and IQ/OQ protocol templates; full validation support and on-site PQ services are available as add-on options.
