ELGA PURELAB Quest Compact Integrated Ultrapure Water System

Overview

The ELGA PURELAB Quest Compact Integrated Ultrapure Water System is an engineered solution for laboratories requiring consistent, multi-grade water—Type I (ultrapure), Type II (pure), and Type III (general laboratory)—from a single, space-optimized platform. Unlike conventional modular systems, the Quest integrates reverse osmosis (RO), electrodeionization (EDI), ultrafiltration, UV photooxidation (185/254 nm), and final polishing in a fully sealed, recirculating architecture. Its core purification principle relies on sequential physical and electrochemical barriers to remove ions, organics, particles, microorganisms, and endotoxins—ensuring continuous compliance with ASTM D1193-20 (Type I), ISO 3696:1987 (Grade 1), and USP for pharmaceutical and analytical applications. Designed for benchtop or wall-mounted deployment, the system delivers real-time, trace-level water quality monitoring without external plumbing or auxiliary hardware.

Key Features

• A4-footprint design (210 × 297 mm) with wall-mount capability—minimizes spatial footprint while maintaining full functionality.
• Triple-grade output from a single feed: Type I ultrapure water (18.2 MΩ·cm, TOC <5 ppb, endotoxins <0.001 EU/mL), Type II pure water, and Type III general lab water—all generated on-demand without cross-contamination.
• Chemical-free, automated disinfection cycle (<2 hours), validated to reduce microbial load by ≥4-log₁₀; no operator intervention required during execution.
• Human-centered consumable architecture: Pre-assembled, twist-lock cartridges enable tool-free replacement in under 90 seconds—even by first-time users.
• Integrated 7 L recirculating reservoir with optional 15 L or 30 L external tanks; RO feed rate of 10 L/h ensures rapid replenishment under variable demand.
• Dispense flow up to 1.2 L/min at point-of-use—reducing wait time for volumetric applications such as buffer preparation and HPLC mobile phase generation.
• Housing constructed from >85% post-industrial recycled polymer—certified per ISO 14021 and aligned with institutional sustainability procurement policies.

Sample Compatibility & Compliance

The PURELAB Quest is validated for use across life science research, clinical diagnostics, pharmaceutical QC, and analytical instrumentation—including LC-MS, ICP-MS, cell culture, ELISA, and molecular biology workflows. Its ultrapure output meets stringent input requirements for sensitive detection systems where background interference from ions, organics, or endotoxins compromises data integrity. The system complies with ASTM D1193-20 (Type I), ISO 3696:1987 (Grade 1), CLSI EP21-A (water purity validation), and USP (Water for Pharmaceutical Purposes). When paired with AQUAVISTA cloud services, it supports 21 CFR Part 11-compliant electronic records, including timestamped audit trails for conductivity, TOC, UV absorbance, temperature, and cartridge usage history—enabling full traceability for GLP and GMP environments.

Software & Data Management

AQUAVISTA integration provides secure, encrypted cloud-based monitoring via web browser or mobile application. Real-time dashboards display live resistivity, TOC, UV transmission, flow rate, and reservoir level. Historical data—spanning 12 months—is exportable in CSV or PDF format for internal review or regulatory submission. USB 2.0 port enables local firmware updates, diagnostic logging, and offline backup of calibration logs and alarm events. All system alerts—including low-resistivity excursions, TOC drift, cartridge saturation, and disinfection status—are time-stamped and stored with metadata (operator ID, location tag, event severity) to satisfy ISO/IEC 17025 clause 7.7 and FDA data integrity expectations.

Applications

• High-sensitivity analytical instrumentation: LC-MS, GC-MS, ICP-OES, and ICP-MS require ultrapure water with sub-ppb metal and organic content to prevent column fouling, detector noise, and spectral interferences.
• Cell and tissue culture: Endotoxin-free (<0.001 EU/mL) and nuclease-free water is essential for media preparation, transfection reagents, and stem cell expansion protocols.
• Molecular biology: PCR, qPCR, NGS library prep, and CRISPR workflows demand low DNase/RNase and TOC levels to avoid amplification bias and false positives.
• Pharmaceutical QC: Complies with USP and Ph. Eur. 2.2.44 for Water for Injection (WFI)-adjacent applications and stability testing preparations.
• Calibration and standard preparation: Traceable resistivity and TOC values support ISO/IEC 17025 method validation for volumetric and gravimetric standards.

FAQ

Does the PURELAB Quest require connection to a dedicated feed water line?
Yes—it is designed for direct connection to potable municipal water meeting local drinking water standards (e.g., WHO Guidelines or EPA 600/R-98/002). Pre-treatment is not required, but inlet pressure must be maintained between 2–6 bar.
Can the system operate unattended overnight or over weekends?
Yes—the automated recirculation loop and periodic self-monitoring ensure stable ultrapure water quality during idle periods; integrated alarms notify users remotely via AQUAVISTA if parameters deviate.
Is the AQUAVISTA cloud service hosted within the EU for GDPR compliance?
Yes—data residency is configurable per customer region; EU customers default to Frankfurt-based AWS infrastructure certified under ISO 27001, SOC 2, and GDPR Article 28 processing agreements.
How often must consumables be replaced under typical usage (20 L/day)?
RO membrane: 2–3 years | EDI stack: 3–5 years | Final polishing cartridge: 6–12 months (monitored via real-time conductivity decay and TOC rise thresholds).
Does the system support third-party printer or LIMS integration?
Yes—via RS232 or TCP/IP protocols using standard HL7 or ASTM E1384 message formats; API documentation available under NDA for custom middleware development.
