Overview
The Ultra Pure Water System Plus-E2R is a dual-grade water purification platform engineered for laboratories requiring concurrent production of Type III purified water and Type I ultra-pure water per GB/T 6682–2008, as well as compliance with ASTM D1193, NCCLS CLSI EP21-A, and CAP water quality guidelines. Designed around a multi-stage purification architecture—including pretreatment (activated carbon + sediment filtration), reverse osmosis (RO), electrodeionization (EDI), and final polishing via ultraviolet (UV) oxidation (185/254 nm) and 0.1 µm ultrafiltration—the system delivers water meeting stringent specifications for trace elemental analysis, biomolecular applications, and high-sensitivity instrumentation. Its closed-loop recirculation loop minimizes stagnation-related microbial regrowth, while integrated real-time resistivity and TOC monitoring ensure continuous verification of water quality at the point of use.
Key Features
- Dual-output capability: Simultaneous production of purified water (≤1 µS/cm) and ultra-pure water (18.2 MΩ·cm @25 °C) from a single unit.
- Integrated UV photo-oxidation: Dual-wavelength (185 nm + 254 nm) lamp reduces TOC to <5 ppb and inactivates microorganisms without chemical addition.
- Endotoxin- and nuclease-free polishing: Optional terminal ultrafilters (0.1 µm PES or PVDF membrane) and affinity cartridges available for removal of endotoxins (<0.001 EU/mL), RNase/DNase, VOCs, EDCs, and sub-ppb organic contaminants.
- Low-power, low-noise operation: Energy-efficient design (50–80 W) with acoustic emission <50 dB(A), suitable for benchtop deployment in shared laboratory environments.
- Intuitive digital interface: Real-time display of resistivity, TOC (optional), flow rate, system pressure, and cartridge service life indicators.
- Modular consumables architecture: Standardized RO, EDI, and polishing cartridges enable rapid replacement and full traceability—each cartridge includes batch-specific performance documentation aligned with ISO 9001 calibration records.
Sample Compatibility & Compliance
The Plus-E2R is validated for compatibility with analytical workflows demanding ultra-low background interference. Its output meets or exceeds water purity requirements for ASTM D1193 Type I, USP <1231>, CLSI EP21-A, and ISO 3696 Class 1 specifications. Critical parameters—including heavy metals (<0.1 ppb), soluble silica (<0.1 ppb), and endotoxin (<0.001 EU/mL)—are verified through quarterly third-party validation per ISO/IEC 17025-accredited protocols. The system supports GLP/GMP-aligned operation via optional audit-trail-enabled software (see Software & Data Management), enabling full traceability for FDA 21 CFR Part 11–compliant environments. All wetted materials comply with USP Class VI biocompatibility standards and are non-leaching under continuous flow conditions.
Software & Data Management
An optional PC-based control module provides centralized system monitoring, historical data logging (resistivity, TOC, flow, pressure, UV intensity), and automated report generation in PDF/CSV formats. Data integrity safeguards include user-level access control (admin/operator/guest), electronic signatures, and tamper-evident audit trails compliant with FDA 21 CFR Part 11 Annex 11 requirements. Raw sensor outputs are timestamped and stored locally on encrypted SD card (optional) with automatic backup to network drives. Calibration logs, maintenance history, and certificate-of-conformance documentation for each consumable lot are automatically linked to operational records.
Applications
This system serves as a primary water source for high-precision analytical instrumentation including HPLC, UHPLC, GC-MS, ICP-MS, ICP-AES, AAS, GFAAS, and TOC analyzers—where particulate, organic, or ionic contamination directly impacts baseline stability and detection limits. It is equally critical for life science applications: mammalian and insect cell culture media preparation, monoclonal antibody production, nucleic acid extraction and sequencing library prep, ELISA and immunohistochemistry, electrophoresis buffer formulation, and endotoxin-sensitive assays (e.g., Limulus Amebocyte Lysate testing). The modular terminal filtration options allow customization for specialized workflows such as CRISPR-Cas9 editing, single-cell RNA-seq, or low-volume LC-MS/MS proteomics.
FAQ
What standards does the Plus-E2R meet for ultra-pure water quality?
It conforms to GB/T 6682–2008 Grade I, ASTM D1193 Type I, ISO 3696 Class 1, and USP <1231> purified water monograph requirements.
Can the system be integrated into a central water distribution network?
Yes—equipped with a recirculating loop interface and optional booster pump, it supports integration into building-wide purified water systems with validated flow velocity (>1 m/s) and temperature control (20–25 °C).
Is TOC monitoring built-in or optional?
TOC measurement is an optional add-on module; base configuration includes real-time resistivity and temperature compensation.
How often do consumables require replacement?
RO membranes: 12–24 months depending on feed water hardness; EDI stacks: 3–5 years; polishing cartridges: 6–12 months or after 1,000–2,000 L of ultra-pure water, whichever occurs first.
Does the system support remote diagnostics?
With the optional Ethernet/Wi-Fi communication module, technicians can perform secure remote firmware updates, diagnostic checks, and predictive maintenance alerts via TLS 1.2–encrypted connection.
