Overview
The Merck Millipore RiOs 5 Ultra Pure Water System is a compact, integrated laboratory water purification platform engineered for the reliable, continuous production of Type III (ISO 3696 / ASTM D1193 Grade III) purified water directly from municipal tap feed water. Utilizing a multi-stage purification architecture—comprising pre-filtration, high-recovery reverse osmosis (RO), and post-RO polishing—the RiOs 5 delivers stable flow rates up to 5 L/h (±15%) with optimized water efficiency. Its design prioritizes operational simplicity, low total cost of ownership, and consistent compliance with international water quality standards for non-critical laboratory applications. The system operates without external pressurization or pretreatment infrastructure, making it suitable for decentralized deployment across core lab environments including central utilities, QC laboratories, and shared instrumentation facilities.
Key Features
- Integrated pre-filtration module with three-stage media: sediment filter, activated carbon block, and scale inhibitor cartridge—installed as a single plug-and-play unit for rapid commissioning and minimal maintenance intervention.
- Advanced high-recovery RO membrane technology featuring an internal recirculation loop that reduces wastewater generation by up to 50% compared to conventional RO systems—enhancing sustainability and lowering utility costs.
- Self-diagnostic RO membrane maintenance protocol with real-time pressure monitoring and automated flush cycles to extend membrane service life and maintain consistent rejection performance.
- Backlit LCD display with intuitive keypad interface providing real-time access to system status, flow rate, conductivity, operating hours, and consumable life indicators.
- Optional 185/254 nm dual-wavelength UV lamp (sold separately) for enhanced microbial control and organic oxidation—recommended for applications requiring reduced endotoxin or TOC levels.
- Compact footprint (45.7 × 25.5 × 31.5 cm) and lightweight construction (14 kg) enable flexible benchtop or under-bench installation without structural reinforcement.
Sample Compatibility & Compliance
The RiOs 5 is validated for use with standard municipal potable water supplies meeting local regulatory requirements (e.g., WHO Guidelines for Drinking-water Quality). It meets ISO 3696:1987 specifications for Type III water (conductivity ≤ 5 µS/cm at 25 °C; total oxidizable carbon ≤ 200 ppb; bacterial count ≤ 10 CFU/mL when equipped with UV option). Electrical safety certification includes UL 61010-1 and cUL listing under File E216983 for Laboratory Use Electrical Equipment. Electromagnetic compatibility complies with EU directives 89/336/EEC and 73/23/EEC. Manufacturing adheres to ISO 9001:2015 (Quality Management) and ISO 14001:2015 (Environmental Management) certified processes.
Software & Data Management
The RiOs 5 operates via embedded firmware with no external software dependency. All operational parameters—including runtime, cartridge replacement alerts, conductivity logging, and system error codes—are stored in non-volatile memory and accessible through the front-panel interface. While the base model does not support network connectivity or electronic audit trails, its event log provides traceable records required for GLP-compliant environments. For laboratories requiring 21 CFR Part 11 compliance, integration with downstream Milli-Q® systems (e.g., Milli-Q IQ 7000) enables full data capture, user authentication, and electronic signature capabilities within a unified water purification workflow.
Applications
- Routine glassware rinsing and final wash stages in analytical and clinical labs.
- Feed water supply for autoclaves, steam generators, humidifiers, and laboratory washers where Type III water is specified.
- Pre-treatment source for Milli-Q® ultrapure water systems, ensuring optimal RO feed quality and extended upstream cartridge lifetime.
- General-purpose buffer preparation, media formulation, and reagent dilution in molecular biology, histology, and environmental testing workflows.
- Supporting non-sensitive instrumental techniques such as UV-Vis spectrophotometry, basic HPLC mobile phase preparation, and immunoassay plate washing.
FAQ
What feed water quality is required for optimal RiOs 5 performance?
Municipal tap water with residual chlorine ≤ 3 mg/L, hardness ≤ 200 ppm CaCO₃, and turbidity ≤ 1 NTU is recommended. Pretreatment may be necessary if feed water exceeds these thresholds.
Can the RiOs 5 be connected to a storage tank or distribution loop?
Yes—the system supports gravity-fed or pressurized distribution via optional pump kits and compatible tubing (e.g., PTFE or polyethylene); however, loop-based configurations require additional microbial control measures.
How often must consumables be replaced?
Pre-filtration cartridges are rated for ~6 months or 1,000 L (whichever occurs first); RO membranes typically last 2–3 years depending on feed water quality and usage patterns.
Is the RiOs 5 suitable for ISO 17025-accredited testing laboratories?
When operated per manufacturer guidelines and maintained with documented calibration and replacement logs, the RiOs 5 satisfies the water quality requirements for supporting ISO/IEC 17025 Clause 6.4 (Equipment) and Clause 6.6 (Traceability of Measurements).
