Overview
The Deepflow CYAKACARE Ultra-Pure Water System (RO Clean A Cleaning Series) is a laboratory-grade water purification platform engineered for consistent production of Type I ultrapure water (ASTM D1193-20) and Type II pure water (ISO 3696:1987 Class 2). Designed specifically for routine cleaning, rinsing, and maintenance of sensitive analytical instrumentation—including HPLC columns, LC-MS interfaces, atomic absorption spectrometers, and semiconductor wafer handling tools—the system integrates multi-stage pretreatment, reverse osmosis (RO), electrodeionization (EDI), and dual-stage ultrafiltration with a final 0.22 µm sterilizing-grade membrane. Its core architecture employs a closed-loop recirculation loop with continuous UV irradiation (254 nm + 185 nm) to suppress microbial regrowth and maintain resistivity ≥18.2 MΩ·cm at 25 °C. Unlike general-purpose deionized water systems, the CYAKACARE is calibrated and validated for low-level organic and ionic carryover—critical when preparing rinse solutions for trace-metal analysis (e.g., ICP-MS sample introduction systems) or particle-sensitive optical components.
Key Features
- Integrated RO + EDI + Dual UF + UV Oxidation: Ensures removal of >99.9% of ions, >99.999% of bacteria, and <5 ppb total organic carbon (TOC)
- Real-time monitoring of resistivity (0.01–18.25 MΩ·cm), TOC (<5 ppb), and temperature (±0.2 °C) via calibrated digital sensors with NIST-traceable calibration records
- Touchscreen HMI with audit trail logging compliant with FDA 21 CFR Part 11 requirements (user authentication, electronic signatures, immutable event history)
- Modular cartridge design enabling rapid replacement of prefilter (5 µm PP), activated carbon, RO membrane, and polishing cartridges without system shutdown
- Automated sanitization cycle using hot water (80 °C) or ozone injection—validated per ISO 14644-1 Class 5 cleanroom protocols for critical rinse applications
- Low-footprint vertical tower configuration with integrated dispensing arm and optional air-gap faucet for laminar-flow hood integration
Sample Compatibility & Compliance
The CYAKACARE is validated for compatibility with glassware, stainless-steel fixtures, PTFE tubing, fused silica capillaries, and quartz cuvettes—materials commonly used in trace elemental and spectroscopic workflows. All wetted components comply with USP Class VI biocompatibility standards and meet EN 61326-1 (EMC) and EN 61010-1 (safety) directives. Water output conforms to ASTM D1193-20 (Type I), CLSI EP23-A (water for clinical laboratories), and ISO 15195:2018 (reference measurement laboratories). System qualification documentation supports IQ/OQ/PQ execution under GLP and GMP environments, including documented flow rate stability (±2% over 8 h), pressure decay testing (<0.5 bar/h), and microbial challenge studies per ISO 11737-1.
Software & Data Management
The embedded firmware supports Ethernet and RS-485 connectivity for integration into centralized laboratory information management systems (LIMS). Raw sensor data—including timestamped resistivity, TOC, UV absorbance at 254 nm, and flow pulse counts—is exported in CSV or XML format with configurable sampling intervals (1 s to 1 h). Audit logs retain all operator actions, alarm events (e.g., low-pressure warning, cartridge life expiration), and calibration entries for ≥12 months. Optional cloud-based remote monitoring (via TLS 1.2–secured API) enables real-time alerts and predictive maintenance scheduling based on cumulative usage metrics.
Applications
- Rinsing of HPLC autosampler needles, detector flow cells, and column frits to prevent carryover in quantitative bioanalysis
- Preparation of blank solvents and mobile phase diluents for LC-MS/MS method validation (per ICH Q2(R2))
- Cleaning of quartz crystal microbalance (QCM) sensors and surface plasmon resonance (SPR) chips prior to ligand immobilization
- Final rinse step in semiconductor photomask cleaning SOPs requiring sub-10 nm particle-free water
- Reagent preparation for ELISA plate washing steps where endotoxin contamination must remain <0.03 EU/mL
- Calibration standard dilution in ion chromatography (IC) systems operating under ISO/IEC 17025-accredited conditions
FAQ
What is the typical service life of the RO membrane under standard lab usage (20 L/day)?
Under continuous operation with municipal feed water (TDS ≤ 250 ppm), the RO membrane maintains ≥95% rejection efficiency for ≥24 months; lifetime is extended with optional feed water softening or antiscalant dosing.
Does the system support third-party validation services for ISO/IEC 17025 accreditation?
Yes—Deepflow provides IQ/OQ protocol templates and collaborates with ISO 17025-accredited metrology labs for on-site performance verification and uncertainty budgeting.
Can the CYAKACARE be integrated into a building’s central purified water network?
It is designed as a point-of-use system; however, a dedicated feed line with backflow prevention and pressure regulation (2–4 bar) enables connection to centralized pre-treated water sources.
Is the UV lamp output monitored and auto-compensated for intensity decay?
Yes—the 185/254 nm dual-wavelength UV module includes real-time photodiode feedback with automatic intensity adjustment and lamp replacement alerts based on cumulative UV dose.
