Overview
The Merck Millipore Elix Advantage is a continuously operating, point-of-use pure water system engineered for reliable production of high-purity Type II water directly from municipal tap feed. Based on a multi-stage purification architecture—comprising integrated pre-filtration, high-recovery reverse osmosis (RO), electro-deionization (EDI), and optional UV irradiation—the system delivers water meeting or exceeding international standards including ISO 3696:2017 Grade 2, ASTM D1193-20 Type II, and BS EN ISO 3696. Designed for laboratories requiring consistent, low-maintenance feedwater for downstream applications—including buffer preparation, cell culture media formulation, analytical instrument rinsing, and as pretreatment for Milli-Q® ultrapure water systems—the Elix Advantage integrates real-time conductivity monitoring at critical process points to ensure uninterrupted compliance with defined purity thresholds.
Key Features
- Integrated modular prefiltration cartridge assembly enabling rapid, tool-free replacement without system shutdown
- Self-regenerating ion exchange resin via continuous electro-deionization (EDI), eliminating chemical regeneration and reducing operational downtime
- High-efficiency reverse osmosis module with recirculation loop achieving >50% reduction in wastewater generation compared to conventional RO configurations
- Optional 254 nm UV lamp (185/254 nm dual-wavelength available upon configuration) for microbial control and TOC reduction in sensitive applications
- Backlit LCD display with intuitive membrane keypad interface providing real-time access to conductivity, flow rate, tank level, and maintenance alerts
- Scalable reservoir options: factory-integrated 30 L, 60 L, or 100 L stainless steel or polyethylene tanks with level sensors and air filtration
- Compliance-ready design supporting audit trails for GLP/GMP environments when paired with optional data logging modules
Sample Compatibility & Compliance
The Elix Advantage is validated for use with standard municipal potable water supplies meeting WHO or local regulatory guidelines for total dissolved solids (TDS) ≤ 500 ppm and chlorine ≤ 3 ppm. All wetted materials—including RO membranes, EDI stacks, and distribution tubing—are certified to USP Class VI and FDA-compliant polymers. The system conforms to UL 61010-1 (Laboratory Equipment Safety), UL/cUL E216983 listing, CE marking under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and is manufactured in facilities certified to ISO 9001:2015 and ISO 14001:2015. It supports pharmacopeial compliance for Purified Water (USP , EP 2.2.42, JP XVII) when used as pretreatment for subsequent polishing stages.
Software & Data Management
While the base Elix Advantage operates via embedded firmware without external PC dependency, optional connectivity modules enable RS232 or Ethernet interfaces for integration into centralized laboratory information management systems (LIMS). Audit-trail-capable data loggers record timestamped conductivity, pressure, UV intensity, and alarm events—supporting 21 CFR Part 11 requirements when deployed with appropriate user access controls and electronic signature protocols. All calibration and service records are stored internally and exportable in CSV format for quality documentation workflows.
Applications
- Preparation of microbiological growth media and sterile irrigation solutions
- Formulation of HPLC mobile phases, electrophoresis buffers, and ELISA reagents
- Feedwater for Milli-Q® IQ series ultrapure water systems and other polishing platforms
- Rinsing and feed supply for clinical analyzers, autoclaves, washer-disinfectors, and environmental chambers
- Hydrogen generator inlet water where low silica and metal content prevent catalyst poisoning
- Agricultural hydroponic nutrient solution dilution requiring low endotoxin and particulate load
FAQ
What feed water quality is required for optimal Elix Advantage performance?
Municipal tap water with TDS ≤ 500 ppm, free chlorine ≤ 3 ppm, and turbidity < 1 NTU is recommended. Pre-treatment with activated carbon and sediment filters is advised if feed water exceeds these limits.
Can the Elix Advantage be connected to multiple points of use?
Yes—when equipped with an appropriately sized reservoir and distribution pump, the system supports up to three simultaneous outlets with pressure-regulated flow, provided total demand remains within rated output capacity (up to 10 L/h at 25 °C).
Is validation documentation available for GxP environments?
Merck provides IQ/OQ protocol templates, material certifications (e.g., USP Class VI), and test reports for conductivity, TOC, and microbial retention. Full PQ execution requires site-specific testing per client SOPs.
How often does the RO membrane require replacement?
Under typical feed conditions and proper prefiltration, RO membrane service life exceeds 2–3 years; system diagnostics monitor differential pressure and rejection rate to indicate timely replacement.
Does the Elix Advantage support remote monitoring?
With the optional Ethernet module and Merck’s LabManager™ software suite, users can configure email alerts, view live parameters, and download historical logs from any network-connected workstation.
