LabArk U24 Ultra-Pure and RO Pure Water Integrated System

Overview

The LabArk U24 Ultra-Pure and RO Pure Water Integrated System is an engineered solution for laboratories requiring dual-grade water production—consistently delivering both Type I ultrapure water (UPW) and Type III reverse osmosis (RO) pure water from a single compact platform. Designed for compliance-driven environments—including pharmaceutical QC labs, academic research facilities, and analytical instrument feed applications—the system employs a multi-stage purification architecture grounded in proven physical and electrochemical principles: pre-filtration, high-rejection RO membrane separation, dual-wavelength UV photooxidation (185/254 nm), ion exchange resin polishing, and final 0.2 µm sterile filtration. Its closed-loop recirculation design ensures continuous UPW conditioning, mitigating stagnation-related microbial regrowth and organic leaching—critical for maintaining long-term resistivity stability and low TOC. The integrated 30 L HDPE storage tank features mercury-free UV irradiation to suppress biofilm formation without introducing hazardous byproducts.

Key Features

• Stable, temperature-compensated RO output at up to 24 L/h—engineered with flow-regulated pumping and pressure-balanced membrane housing to minimize fluctuations across ambient variations.
• Automated non-conforming water rejection: RO permeate failing conductivity thresholds (<20 µS/cm) is diverted and not stored, preserving reservoir integrity.
• Continuous UPW recirculation loop incorporating 185 nm UV oxidation and dual-stage ion exchange, ensuring TOC <5 ppb and resistivity maintained at 18.2 MΩ·cm (25°C) under steady-state operation.
• Modular, tool-free consumables architecture—resin cartridges, terminal filters, and UV lamps feature color-coded housings and keyed insertion to prevent misinstallation; all user-replaceable without technical support.
• Touchscreen HMI with real-time display of feed/RO/UP conductivity, resistivity, TOC, temperature, flow rate, and alarm status—supporting volume-based dispensing, adjustable flow control (0–2 L/min), and manual override functions.
• Embedded data logger retaining ≥24 months of timestamped operational parameters (pressure, temperature, conductivity, UV intensity, cartridge usage hours)—exportable via USB or network interface in CSV format.

Sample Compatibility & Compliance

The LabArk U24 meets the stringent water purity requirements defined in multiple international standards governing analytical and regulatory workflows. Its UPW output satisfies ASTM D1193-06 Type I, ISO 3696:1987 Grade 1, and GB/T 6682-2008 Class I specifications—including maximum allowable limits for conductivity (≤0.055 µS/cm), TOC (≤5 ppb), particle count (>0.22 µm), and microbial content (<0.01 CFU/mL). For GLP/GMP-aligned operations, the system supports audit-ready documentation: full traceability of consumable lifecycle (serial-numbered cartridges with RFID-tagged installation logs), electronic signature-capable software (optional FDA 21 CFR Part 11 module), and immutable event logging with time-stamped operator actions. RO water complies with ASTM D1193-06 Type III and GB/T 11446.1-2013 E1 specifications—suitable for glassware rinsing, buffer preparation, and feed water for HPLC, LC-MS, and ICP-MS systems.

Software & Data Management

Data integrity is ensured through embedded firmware compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). All operational events—including power cycles, alarm triggers, cartridge replacement confirmations, and manual dispensing entries—are logged with UTC timestamps and operator ID (if configured). Export formats include time-synchronized CSV files compatible with LIMS integration. Network-enabled units support remote diagnostics via secure HTTP/S protocols; optional SNMP integration allows centralized monitoring across multi-system lab deployments. No cloud dependency: all data remains on-device unless explicitly transferred via authenticated USB or LAN session.

Applications

• Feed water for high-sensitivity analytical instrumentation: HPLC, UHPLC, LC-MS, GC-MS, ICP-OES, and ICP-MS—where trace metal contamination or organic interference must be minimized.
• Preparation of cell culture media, electrophoresis buffers, and molecular biology reagents (e.g., PCR, sequencing, NGS library prep) requiring endotoxin-free, nuclease-free water.
• Calibration standard dilution, reference material preparation, and trace elemental analysis in environmental and clinical testing labs.
• General laboratory use including glassware washing, autoclave feed, and reagent formulation where consistent Type III RO water and on-demand Type I UPW are simultaneously required.

FAQ

What standards does the LabArk U24 comply with for ultrapure water?
It meets or exceeds ASTM D1193-06 Type I, ISO 3696:1987 Grade 1, GB/T 6682-2008 Class I, and GB/T 33087-2016 high-purity water specifications.
Can the system operate continuously without manual intervention?
Yes—the automated recirculation loop, self-diagnostic sensors, and scheduled maintenance alerts enable unattended 24/7 operation when connected to stable feed water and power.
Is the 30 L tank expandable?
Yes—modular tank interface supports field-upgrade to larger HDPE reservoirs with compatible UV disinfection modules.
How is data security handled during export?
USB exports require physical authentication; LAN transfers use TLS 1.2 encryption and role-based access controls configurable via admin credentials.
Are consumables certified for trace metal leaching?
All resin cartridges and filtration components undergo batch-certified testing per ASTM F2098 for extractables, with CoA documentation available upon request.
