Think-lab Labonova Direct Pro S Integrated Pure & Ultrapure Water System

Overview

The Think-lab Labonova Direct Pro S is an integrated, modular pure and ultrapure water system engineered for laboratories requiring continuous, on-demand access to both ASTM Type II pure water and ASTM Type I ultrapure water from a single platform. It utilizes a multi-stage purification architecture beginning with pretreatment of municipal tap water, followed by high-efficiency reverse osmosis (RO) with >75% recovery rate—minimizing wastewater generation while maintaining consistent feed pressure and membrane longevity. Post-RO water undergoes continuous deionization via proprietary mixed-bed ion exchange (DI) modules, achieving stable conductivity of 0.1–0.2 µS/cm—suitable for general lab applications including buffer preparation, glassware rinsing, and feed water for analytical instruments. The final polishing stage employs dual-wavelength (185/254 nm) UV oxidation combined with ultra-low leaching final cartridge filtration to deliver ultrapure water meeting or exceeding the most stringent international specifications: resistivity ≥18.2 MΩ·cm at 25 °C, TOC <5 ppb, total viable count <0.001 CFU/mL, and endotoxin concentration <0.001 EU/mL. This performance aligns with ASTM D1193-20, CLSI EP22-A, and ISO 3696:1999 Class 1 requirements—and supports GLP/GMP-compliant workflows where water quality traceability is essential.

Key Features

• Modular dual-grade output: Simultaneous production of Type II pure water (16 L/h) and Type I ultrapure water (2.0 L/min) from one compact unit.
• High-recovery reverse osmosis: Optimized energy and water efficiency with >75% recovery, reducing operational cost and environmental impact.
• Proprietary DI module: Regenerable mixed-bed resin ensures stable low-conductivity output without chemical regeneration downtime.
• Dual-wavelength UV system: 185 nm photolysis for organic oxidation and 254 nm germicidal irradiation—integrated upstream of final polishing to suppress microbial regrowth and reduce TOC.
• Real-time TOC monitoring: Built-in online TOC sensor provides continuous, non-destructive measurement with data logging capability.
• Intelligent recirculation: Programmable automatic flush cycle maintains loop hygiene and extends consumables lifetime—critical for long-term system stability.
• 7-inch multilingual touchscreen: Intuitive interface supporting English, German, French, and Chinese; enables full system configuration, alarm management, and maintenance scheduling.
• Flexible dispensing architecture: Two independent outlets—one fixed wall- or bench-mounted dispenser, and one ergonomic handheld wand with 1.5 m reinforced PFA tubing—enabling precise delivery across diverse workspaces.

Sample Compatibility & Compliance

The Labonova Direct Pro S is validated for compatibility with a broad range of laboratory applications requiring strict water purity control. Its ultrapure water output meets the input specifications for HPLC, LC-MS, ICP-MS, AAS, cell culture media preparation, molecular biology (e.g., PCR, sequencing), and trace elemental analysis. All wetted materials—including tanks, piping, and cartridges—are constructed from pharmaceutical-grade, low-leaching polymers (e.g., polypropylene, PFA, and stainless steel 316L) compliant with USP Class VI and FDA 21 CFR Part 11–ready audit trail functionality when paired with optional software packages. System design adheres to ISO 9001-certified manufacturing processes in Germany and conforms to CE, RoHS, and WEEE directives. Routine calibration and validation support documentation—including IQ/OQ templates—is provided for regulatory submissions under FDA 21 CFR Part 11, EU Annex 11, and ISO/IEC 17025 frameworks.

Software & Data Management

The embedded control firmware supports time-stamped event logging (including alarms, consumable status, flow anomalies, and TOC excursions) with exportable CSV reports via USB or Ethernet. Optional Think-lab AquaLink™ software enables remote monitoring, user access level management (admin/operator), electronic signature capture, and integration into enterprise LIMS environments. All data—including TOC trends, UV lamp hours, and DI exhaustion curves—is stored locally with battery-backed memory retention (>72 h power loss resilience). Audit trails are immutable and timestamped to meet ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).

Applications

• HPLC and UHPLC mobile phase preparation and instrument rinsing
• LC-MS and GC-MS solvent blanks and calibration standards
• ICP-MS and ICP-OES sample dilution and nebulizer feed
• Cell culture media formulation and sterile filtration support
• Molecular biology workflows: DNA/RNA extraction buffers, electrophoresis, qPCR master mixes
• Pharmaceutical QC testing per USP Water for Pharmaceutical Purposes
• Reference material preparation and certified standard dilutions

FAQ

What is the expected service life of the DI module under typical lab usage?
With average daily ultrapure water consumption of 40–60 L, the DI module typically lasts 6–12 months depending on inlet water hardness and chlorine load; real-time conductivity trending alerts users to scheduled replacement.
Can the system be integrated into an existing lab water distribution network?
Yes—the Direct Pro S supports optional loop recirculation kits with temperature-controlled circulation pumps and sanitary fittings compatible with ASTM F2100-compliant distribution manifolds.
Is TOC monitoring mandatory for all applications?
While not universally required, TOC verification is strongly recommended for LC-MS, trace metal analysis, and biopharmaceutical applications where organic contamination compromises detection limits or column integrity.
How does the automated flush cycle improve system reliability?
It prevents biofilm formation in stagnant zones, reduces resin channeling in DI columns, and maintains consistent UV transmittance—thereby extending consumable life and minimizing unscheduled downtime.
Does the system support 21 CFR Part 11 compliance out of the box?
Hardware-level audit trail logging is built-in; full Part 11 compliance (electronic signatures, role-based access, secure archive) requires AquaLink™ software with validated installation and configuration protocols.
