Overview
The Deepflow CYTTEDI03 EDI Module is a compact, continuous electrodeionization unit engineered for integration into laboratory-scale ultra-pure water (UPW) systems. It operates on the principle of electrochemical ion removal—combining ion-exchange membranes, mixed-bed resin, and direct current to continuously deionize pretreated feed water (typically from reverse osmosis) without chemical regeneration. Unlike conventional mixed-bed polishing, the CYTTEDI03 delivers stable resistivity ≥18.2 MΩ·cm at 25 °C, with TOC levels consistently below 5 ppb and microbial counts <0.1 CFU/mL—meeting ASTM D1193 Type I and ISO 3696 Grade 1 specifications for analytical and life science applications. Its 3 L/h nominal flow rate supports benchtop purification systems serving single or clustered workstations in QC labs, R&D facilities, and university core facilities requiring uninterrupted, high-fidelity water for HPLC mobile phase preparation, cell culture media formulation, and trace elemental analysis.
Key Features
- Continuous Electrodeionization Architecture: Eliminates need for periodic resin replacement or acid/base regeneration—reducing operational downtime and chemical handling hazards.
- Integrated Resin-Membrane Stack: Proprietary mixed-bed ion-exchange resin packed between cation- and anion-selective membranes ensures uniform current distribution and long-term ion removal efficiency.
- Real-Time Conductivity Monitoring: Built-in dual-sensor array measures inlet (RO permeate) and outlet (ultra-pure) conductivity, enabling automated performance diagnostics and alert thresholds.
- Modular Design: Standardized DIN-rail mounting and quick-connect fluid ports simplify retrofitting into existing Deepflow or third-party UPW platforms (e.g., as a drop-in replacement for legacy polishing cartridges).
- Low-Energy Operation: Optimized electrode geometry and pulsed DC power control reduce specific energy consumption to ≤0.8 kWh/m³ at rated flow—compliant with ISO 50001 energy management benchmarks.
- IP54 Enclosure Rating: Dust- and splash-resistant housing suitable for controlled laboratory environments with ambient humidity up to 80% RH.
Sample Compatibility & Compliance
The CYTTEDI03 accepts feed water meeting standard RO output specifications: silica <0.1 mg/L, hardness <0.05 ppm as CaCO₃, total organic carbon <500 ppb, and free chlorine <0.05 ppm. It is validated for use with feed sources compliant with NSF/ANSI 58 and GB/T 5750.4–2023 (Chinese National Standard for Drinking Water Quality). All wetted materials—including polypropylene housing, PVDF tubing, and sulfonated/quinone-type ion-exchange membranes—conform to USP Class VI biocompatibility testing and FDA 21 CFR 177.1520 for repeated food-contact use. System documentation supports GLP/GMP audit readiness, including calibration logs, maintenance records, and IQ/OQ protocol templates aligned with ISO/IEC 17025 requirements.
Software & Data Management
While the CYTTEDI03 operates as a standalone hardware module, its optional RS485 Modbus RTU interface enables seamless integration with central water system controllers (e.g., Deepflow AquaLink™ or LabVantage LIMS). Real-time parameters—including voltage across the stack, current draw, inlet/outlet conductivity, and cumulative runtime—are timestamped and exportable in CSV format. Audit-trail functionality complies with FDA 21 CFR Part 11 when deployed within validated software ecosystems, ensuring electronic record integrity, user authentication, and change history tracking for regulatory submissions.
Applications
- HPLC and UHPLC mobile phase preparation where low TOC and ionic contamination are critical to column longevity and baseline stability.
- Preparation of reagent-grade solutions for ICP-MS, AAS, and ion chromatography requiring sub-part-per-trillion metal ion limits.
- Cell and tissue culture media formulation demanding endotoxin-free, low-nucleotide water per ATCC guidelines.
- Pharmaceutical QC testing per USP “Water for Pharmaceutical Purposes” and EP 2.2.44 “Water for Injection” specifications.
- Calibration of conductivity and TOC analyzers in metrology laboratories accredited to ISO/IEC 17025.
FAQ
What feed water quality is required for optimal CYTTEDI03 performance?
RO permeate with conductivity ≤5 µS/cm, silica <0.1 mg/L, and TOC <500 ppb is recommended. Pre-treatment with activated carbon and 5-µm sediment filtration is mandatory.
Can the module be operated intermittently or must it run continuously?
It is designed for continuous operation; extended shutdown (>8 hours) requires membrane wetting preservation per manufacturer’s SOP to prevent resin desiccation and channeling.
Does the CYTTEDI03 meet ISO 14644-1 Class 5 cleanroom water requirements?
When integrated into a fully validated UPW system with 0.1-µm final filtration and UV oxidation, the combined output satisfies ISO 14644-1 airborne particle limits for water used in Class 5 cleanrooms.
Is remote monitoring supported out-of-the-box?
No standalone Ethernet or Wi-Fi capability is included; remote access requires integration via Modbus RTU into an external SCADA or building management system.
What is the expected service life under typical lab usage?
With proper feed water conditioning and quarterly preventive maintenance, the resin-membrane stack maintains ≥95% of initial ion removal efficiency for ≥24 months or 15,000 operating hours—whichever occurs first.
