中科奥博 TL-10 Laboratory Ultra Pure Water System

Overview

The Zhongke Aobo TL-10 Laboratory Ultra Pure Water System is an integrated, dual-loop water purification platform engineered for precision analytical laboratories requiring consistent, on-demand access to both Type I ultrapure water and Type III purified water—directly from municipal tap feed. It employs a multi-stage purification architecture combining pre-filtration, reverse osmosis (RO), electrodeionization (EDI) or mixed-bed ion exchange (depending on configuration), dual-wavelength UV oxidation (185/254 nm), and final 0.1 µm ultrafiltration. This design ensures removal of ions, colloids, organic compounds, microorganisms, endotoxins, and submicron particulates—meeting or exceeding the stringent specifications defined in GB/T 6682–2008 (equivalent to ISO 3696:1987 Class 1 and ASTM D1193–20 Standard Specification for Reagent Water). The system operates under continuous monitoring and automatic regeneration protocols, minimizing manual intervention while maintaining long-term stability and reproducibility essential for trace-level analytical workflows.

Key Features

• Microprocessor-controlled operation with intuitive touch interface and multilevel menu navigation supporting real-time parameter adjustment and user-defined protocols
• Large backlit blue LCD display showing real-time resistivity, TOC, temperature, flow rate, pressure differentials, and consumable life status
• Dual independent output streams: purified water (≤1 µS/cm) and ultrapure water (≥18.25 MΩ·cm @ 25 °C, TOC < 10 ppb)
• Comprehensive alarm system with audible/visual alerts for low feed pressure, high TOC, cartridge exhaustion, UV lamp failure, reservoir overflow, and leak detection
• Automated daily recirculation and periodic sanitization cycles to suppress biofilm formation and maintain microbial integrity
• Programmable dispensing modes: volume-based, quality-triggered, time-scheduled, and manual override—with customizable setpoints for conductivity/resistivity thresholds
• Multi-tier security architecture including password-protected access levels, audit trail logging (optional USB/RS-485), and configurable maintenance timers
• Modular consumable design with RFID-tagged cartridges enabling automated usage tracking and predictive replacement scheduling
• Integrated clock and calendar function supporting GLP-compliant timestamping of all critical events and dispense records
• Energy-efficient design (50–80 W nominal), compatible with pressurized storage tanks or gravity-fed reservoirs (optional)

Sample Compatibility & Compliance

The TL-10 delivers water suitable for direct use in high-sensitivity instrumentation where background interference must be minimized—including atomic absorption spectroscopy (AAS), inductively coupled plasma optical emission spectrometry (ICP-OES), inductively coupled plasma mass spectrometry (ICP-MS), liquid chromatography–mass spectrometry (LC-MS), ion chromatography (IC), and high-performance liquid chromatography (HPLC). Its output complies with key international standards: GB/T 6682–2008 Grade I (Type I), ISO 3696:1987 Class 1, and ASTM D1193–20 Type I. While not inherently 21 CFR Part 11 compliant out-of-the-box, the optional data logging module (USB/RS-485) supports export of time-stamped operational logs and water quality metrics—enabling integration into laboratory information management systems (LIMS) and facilitating GMP/GLP audit readiness when paired with appropriate SOP documentation and electronic signature validation.

Software & Data Management

The TL-10 supports optional connectivity via RS-485 serial interface or USB port for local data acquisition. When connected to a host PC, the system records up to 12 months of historical data—including resistivity, TOC, temperature, total dispensed volume, alarm events, and cartridge usage duration. Exported logs are formatted as CSV files for downstream analysis in Excel or LIMS platforms. Optional mobile application support enables remote monitoring of system status, real-time water quality metrics, historical dispense logs, consumable lifespan indicators, and event-driven push notifications (e.g., filter replacement due, UV lamp degradation warning). All stored data include immutable timestamps and user identifiers, forming a foundational layer for regulatory traceability in regulated environments.

Applications

• Preparation of calibration standards and blank solutions for elemental analysis (AAS, ICP-OES, ICP-MS)
• Mobile phase preparation and instrument rinsing in HPLC, UHPLC, and LC-MS systems
• Solvent formulation and reagent dilution in trace organic analysis and pharmaceutical QC testing
• Cell culture media preparation and molecular biology applications requiring low endotoxin and nuclease-free water
• Rinsing of optical components, semiconductor wafers, and photomask substrates in cleanroom environments
• Electrochemical measurements requiring minimal ionic background and stable baseline conductivity
• Calibration and verification of conductivity, TOC, and particle counters used in water quality assurance programs

FAQ

What is the minimum feed water quality required for optimal TL-10 performance?
The system is designed for municipal tap water with TDS ≤ 200 ppm, pressure between 1.0–5.0 kg/cm² (0.1–0.5 MPa), and temperature range of 5–45 °C. Pre-treatment (e.g., sediment/carbon filtration) is recommended if feed water exceeds these limits.
Can the TL-10 produce water compliant with USP Purified Water or Water for Injection (WFI) specifications?
No—the TL-10 meets Type I ultrapure water requirements per GB/T 6682–2008 and ISO 3696 Class 1, but it does not satisfy USP WFI criteria (e.g., bacterial endotoxin limit ≤ 0.25 EU/mL, mandatory distillation or equivalent validated process).
How often do consumables require replacement?
Pre-filters: every 3–6 months; RO membrane: 2–3 years; EDI/mixed-bed cartridge: 6–12 months depending on feed water quality and daily usage volume. The system provides real-time usage tracking and proactive alerts.
Is the TL-10 suitable for ISO 17025-accredited testing laboratories?
Yes—when operated within validated procedures, with documented maintenance logs, calibrated sensors, and traceable consumables, the TL-10 supports ISO/IEC 17025 clause 5.5.2 (environmental conditions) and clause 5.9 (assuring validity of results) through consistent delivery of certified-grade water.
Does the system support external storage tank integration?
Yes—both pressurized stainless-steel tanks and passive polyethylene reservoirs can be connected via standard 1/4″ tubing ports, with level-sensing compatibility for automated fill control.
