Overview
The ELGA PURELAB Option-Q 7/15 is a compact, point-of-use ultra-pure water system engineered for laboratories requiring consistent, high-fidelity Type I water directly from municipal tap supply. Based on multi-stage purification architecture—including activated carbon prefiltration, reverse osmosis (RO), electrodeionization (EDI), and dual-wavelength UV oxidation—the system delivers water meeting or exceeding ASTM D1193-20 Type I, ISO 3696:1987 Grade 1, and CLSI EP22-A standards. Its core performance metric—18.2 MΩ·cm resistivity at 25 °C—reflects near-theoretical deionization efficiency, while low TOC (1–3 ppb) and sub-part-per-trillion endotoxin levels (<0.001 EU/mL) support sensitive applications such as HPLC mobile phase preparation, cell culture media formulation, and molecular biology workflows including qPCR and CRISPR-based assays. The system operates with either 7 L/h or 15 L/h nominal output capacity, sustaining up to 1 L/min dispensing flow at full resistivity—enabling uninterrupted operation during high-throughput bench use.
Key Features
- Integrated dual-wavelength (185 nm + 254 nm) UV chamber for continuous TOC reduction and microbial inactivation
- Electrodeionization (EDI) module eliminating need for chemical regeneration and ensuring stable ion removal without resin exhaustion cycles
- Dockable reservoir interface supporting closed-loop recirculation to maintain constant resistivity and suppress biofilm formation in distribution lines
- Optional ELGA Biofilter cartridge (0.1 µm hydrophilic PES membrane) reducing viable microorganisms to <0.1 CFU/mL and providing additional endotoxin retention
- Real-time conductivity/resistivity monitoring with temperature compensation per IEC 60746-3, plus digital logging of all critical parameters
- Modular design facilitating field replacement of consumables—including RO membranes, EDI stacks, and UV lamps—without system downtime
Sample Compatibility & Compliance
The PURELAB Option-Q 7/15 is validated for compatibility with ultrapure water-dependent instrumentation including LC-MS, ICP-MS, atomic absorption spectrometry, and next-generation sequencing platforms. It conforms to key regulatory frameworks governing laboratory water quality: ASTM D1193-20 (Type I), ISO 3696:1987 (Grade 1), USP , and CLSI EP22-A. When equipped with the Biofilter option, the system supports GLP- and GMP-aligned environments through audit-ready event logs, user-access controls, and configurable alarm thresholds compliant with FDA 21 CFR Part 11 requirements for electronic records and signatures. All wetted materials—including fluid paths, tanks, and filters—are USP Class VI-certified and extractables-tested per ISO 10993-12.
Software & Data Management
The system features an embedded controller with non-volatile memory storing ≥12 months of operational history—including resistivity trends, UV lamp runtime, filter saturation indicators, and alarm events. Data export is supported via USB port in CSV format for integration into LIMS or QA documentation systems. Optional Ethernet connectivity enables remote monitoring through ELGA’s centralized fleet management portal, where users can configure email/SNMP alerts, review calibration histories, and generate compliance reports traceable to individual instrument serial numbers. Audit trails record all parameter changes, user logins, and maintenance interventions with timestamped, immutable entries.
Applications
- HPLC and UHPLC mobile phase and blank preparation
- Cell culture media and reagent dilution where endotoxin and nuclease contamination must be minimized
- Preparation of standards and calibration solutions for trace elemental analysis (ICP-OES, ICP-MS)
- Buffer formulation for protein purification and electrophoresis
- Genomic applications including RNA isolation, RT-qPCR, and NGS library prep
- Pharmaceutical QC testing requiring USP compliant water
FAQ
Is the PURELAB Option-Q 7/15 still in active production?
No—manufacturing ceased at ELGA’s UK facility in 2023. However, authorized distributors maintain limited inventory in select APAC markets, and full technical support—including spare parts and consumables—is guaranteed through December 2026.
Can this system be integrated into an existing lab water network?
Yes—it supports both direct dispensing and connection to a recirculating loop via its dockable reservoir interface. Integration requires compatible stainless-steel or fluoropolymer piping and pressure-regulated return line configuration.
What validation documentation is provided with the system?
Each unit ships with a Factory Acceptance Test (FAT) report, Certificate of Conformance, and IQ/OQ protocol templates aligned with ISO/IEC 17025 and GAMP 5 guidelines.
How frequently must consumables be replaced?
RO membranes: every 12–24 months depending on feed water hardness; EDI stacks: 3–5 years; UV lamps: annually; Biofilter cartridges: every 6 months under continuous use or after 1,000 L throughput.
