Thermo Fisher GenPure Pro Ultra Pure Water System

Overview

The Thermo Fisher GenPure Pro Ultra Pure Water System is an engineered solution for laboratories requiring continuous, on-demand production of Type I ultrapure water compliant with ASTM D1193, ISO 3696 Grade 1, CLSI, and USP standards. It employs a multi-stage purification architecture—comprising dual-stage reverse osmosis pretreatment, electrodeionization (EDI), dual-wavelength UV photooxidation (185 nm and 254 nm), and final polishing via ultra-low-adsorption ion-exchange and 0.1 µm sterile filtration—to achieve resistivity ≥18.2 MΩ·cm at 25°C, TOC ≤5 ppb, endotoxin <0.001 EU/mL, and microbial levels below detectable limits. The system integrates real-time electrochemical monitoring of conductivity/resistivity using a temperature-compensated platinum chip sensor (electrode constant 0.01 cm⁻¹) and automatic calibration prior to each measurement, ensuring traceable, metrologically sound water quality assurance.

Key Features

• Integrated dual-wavelength UV oxidation (185 nm + 254 nm) with continuous UV intensity monitoring—prevents under-dosed irradiation and eliminates false-low TOC readings caused by lamp aging or quartz sleeve fouling.
• Real-time online TOC measurement with photometric detection; dynamic range 1–5 ppb; fully compensated for temperature, flow rate, and UV output drift.
• Intelligent dispensing module with POM precision valve and microprocessor-controlled volume delivery (0.01–65 L, ±0.5% accuracy); programmable dispense volume, flow rate, and pause intervals.
• Modular quick-change cartridge design with leak-proof push-fit connections—filter replacement completed in <5 seconds without system shutdown or tools.
• GLP-compliant operating system featuring password-protected parameter access, audit-trail-enabled event logging (including error codes, timestamps, and operator IDs), and RS232 data export with configurable transmission intervals.
• Tilt-adjustable ergonomic control panel with 4-line alphanumeric display; intuitive navigation for system status, maintenance alerts, calibration history, and real-time water quality metrics.

Sample Compatibility & Compliance

The GenPure Pro delivers water suitable for critical applications including HPLC mobile phase preparation, LC-MS solvent formulation, cell culture media supplementation, molecular biology workflows (e.g., PCR, qRT-PCR, NGS library prep), and trace metal analysis. Its RNase (<0.003 ng/mL) and DNase (<0.4 pg/µL) specifications meet stringent requirements for nucleic acid integrity preservation. All internal wetted materials—including high-purity PVDF, PEEK, and electropolished 316L stainless steel—are certified extractables-free per USP . The system supports full 21 CFR Part 11 readiness when paired with Thermo Fisher’s optional LabManager software suite, enabling electronic signatures, role-based access control, and secure data archiving for regulated environments.

Software & Data Management

Built-in microprocessor firmware continuously logs operational parameters—including feedwater conductivity, UV lamp hours, filter saturation indicators, TOC excursions, and temperature-compensated resistivity—over a rolling 28-day window. Error events are timestamped, categorized (e.g., “Low UV Intensity”, “Cartridge Life Exceeded”, “Flow Anomaly”), and stored with diagnostic context. Data export via RS232 allows seamless integration with LIMS or ELN platforms. Optional LabManager software extends functionality with remote monitoring, predictive maintenance scheduling, automated compliance report generation (per ISO/IEC 17025 or GLP Annex 3), and digital signature validation for audit-ready documentation.

Applications

• HPLC and UHPLC mobile phase and blank preparation where low TOC and ionic contamination prevent baseline drift and column fouling.
• LC-MS and ICP-MS analysis requiring sub-part-per-trillion metal purity and absence of carbonaceous background interference.
• Mammalian and stem cell culture systems dependent on endotoxin-free, nuclease-free water to maintain viability and differentiation fidelity.
• Next-generation sequencing library construction and CRISPR-Cas9 editing workflows sensitive to RNase/DNase carryover.
• Pharmaceutical QC testing aligned with USP and EP 2.2.44 water quality monographs for purified and water-for-injection (WFI) support processes.

FAQ

What standards does the GenPure Pro comply with?
ASTM D1193 Type I, ISO 3696 Grade 1, CLSI GP30-A3, USP , and EP 2.2.44. Full compliance documentation—including factory calibration certificates and material biocompatibility reports—is provided with each unit.
Can the system be integrated into a centralized lab water network?
Yes—the GenPure Pro supports loop-compatible operation with optional recirculation pump and sanitary tri-clamp fittings. It interfaces with building management systems via analog 4–20 mA output for feedwater pressure and resistivity signals.
How is TOC accuracy maintained over time?
TOC sensor auto-zeroing occurs during every idle cycle; UV lamp intensity is monitored in real time and triggers recalibration if output falls below 85% nominal. Annual sensor verification using certified KHP standards is recommended.
Is remote diagnostics supported?
With LabManager software license and Ethernet adapter (optional), users gain secure web-based access to live water quality dashboards, historical trend charts, and proactive alert notifications via email or SMS.
What maintenance intervals are recommended?
Pre-filters: 6 months or 1,500 L, whichever comes first. EDI stack: 24 months under typical feedwater conditions (TDS <200 ppm). UV lamps: 12 months or 9,000 hours. Polishing cartridges: 6–12 months depending on usage volume and inlet water quality. All are tracked automatically and displayed on the control panel.
