Think-lab Labonova Direct Pro+ Intelligent Pure & Ultrapure Water System

Overview

The Think-lab Labonova Direct Pro+ is an integrated, intelligent pure and ultrapure water system engineered for laboratories requiring simultaneous, on-demand access to both ASTM Type II purified water and ASTM Type I ultrapure water — all from a single compact unit. It employs a multi-stage purification architecture beginning with pre-treatment of municipal feed water, followed by high-recovery reverse osmosis (RO) with >75% recovery efficiency, electro-deionization (EDI), dual-wavelength ultraviolet oxidation (185 nm + 254 nm), ultrafiltration (UF), and final polishing via ion-exchange and activated carbon media. This cascaded process ensures consistent production of ultrapure water meeting or exceeding the most stringent international standards — including ASTM D1193-20, CLSI EP22-A, and ISO 3696:1987 Class 1 — while delivering Type II water at up to 20 L/h and Type I water at up to 2.0 L/min. The system’s closed-loop recirculation design, coupled with programmable auto-flush cycles, minimizes biofilm formation and extends consumables lifetime without compromising water quality integrity.

Key Features

• Simultaneous dual-grade output: Independent, metered delivery of ASTM Type II and Type I water from one platform — eliminating the need for separate systems.
• High-efficiency RO module with >75% water recovery rate, reducing wastewater volume and operational cost.
• Integrated EDI module enabling continuous deionization without chemical regeneration — ensuring stable conductivity (0.055 µS/cm) and resistivity (18.2 MΩ·cm @ 25°C) in ultrapure water.
• Dual-wavelength UV system (185 nm for TOC oxidation; 254 nm for microbial inactivation) combined with real-time online TOC monitoring (<1–3 ppb).
• 0.2 µm ultrafiltration membrane certified nuclease-free (DNase-, RNase-, DNA-free) and endotoxin-retentive (<0.001 EU/mL).
• 7-inch full-color touchscreen interface supporting English, German, French, and Chinese — configurable for wall-mount or benchtop installation.
• Energy-optimized operating modes, including standby, scheduled start-up, and adaptive flow-based power management.
• Two independent point-of-use dispensers: fixed wall-mounted faucet + flexible handheld wand with 1.2 m reinforced hose for ergonomic, contamination-controlled dispensing.

Sample Compatibility & Compliance

The Labonova Direct Pro+ is validated for use in analytical, life science, and pharmaceutical laboratories where water purity directly impacts assay fidelity and regulatory compliance. Its ultrapure water output satisfies critical requirements for HPLC mobile phase preparation, cell culture media formulation, molecular biology applications (e.g., PCR, sequencing, transfection), and trace metal analysis. The system adheres to Good Laboratory Practice (GLP) and supports audit-ready operation through time-stamped event logging, user-access controls, and full traceability of maintenance history. While not inherently 21 CFR Part 11 compliant out-of-the-box, its data export capabilities (via USB or optional Ethernet) facilitate integration into validated environments under FDA, EMA, or MHRA oversight when paired with appropriate SOPs and IT validation protocols.

Software & Data Management

The embedded control firmware provides comprehensive system diagnostics, predictive maintenance alerts (e.g., cartridge saturation, UV lamp aging, TOC drift), and customizable alarm thresholds. All operational parameters — including conductivity, resistivity, TOC, UV intensity, pressure differentials, and flow rates — are continuously logged with timestamps and stored onboard for ≥12 months. Data export is supported in CSV format via USB port. Optional network connectivity enables remote monitoring and centralized fleet management across multi-site laboratory infrastructures. Audit trails include user login/logout events, parameter modifications, and service interventions — aligning with GLP/GMP documentation expectations.

Applications

• HPLC, UHPLC, and LC-MS mobile phase and blank preparation
• Cell culture media, buffer, and reagent dilution where endotoxin and nuclease contamination must be eliminated
• PCR, qRT-PCR, NGS library prep, and CRISPR-based workflows requiring DNase/RNase-free water
• Atomic absorption spectroscopy (AAS), ICP-OES, and ICP-MS calibration standard preparation
• Electrophysiology and patch-clamp experiments sensitive to ionic impurities
• Pharmaceutical QC testing per USP and EP 2.2.44 water specifications

FAQ

What standards does the Direct Pro+ ultrapure water meet?
It meets or exceeds ASTM Type I, ISO 3696 Class 1, and CLSI EP22-A specifications for resistivity (≥18.2 MΩ·cm), TOC (<1–3 ppb), bacteria (<0.01 CFU/mL), and endotoxin (<0.001 EU/mL).
Can the system be connected to a central water distribution loop?
Yes — the Direct Pro+ supports optional pressurized loop integration via external pump and loop monitor modules for facility-wide ultrapure water distribution.
How often do consumables require replacement?
Pre-filters: every 6 months (or per pressure differential alert); RO membrane: 2–3 years; EDI stack: 3–5 years; UF/UV/TOC modules: 12–24 months — all tracked and reported via the touchscreen interface.
Is remote monitoring available?
Standard USB data export is included; Ethernet or Wi-Fi connectivity is available as a factory-configurable option for secure remote diagnostics and log retrieval.
Does the system support IQ/OQ documentation packages?
Yes — Think-lab provides vendor-validated Installation Qualification (IQ) and Operational Qualification (OQ) templates aligned with ISO/IEC 17025 and GAMP5 guidelines, intended for customer-executed Performance Qualification (PQ).
