Overview
The Merck Millipore RiOs 5 Ultra Pure Water System is a compact, wall- or bench-mountable laboratory water purification platform engineered to produce consistent Type III (ISO 3696 / ASTM D1193 Grade III) purified water directly from municipal tap feedwater. It employs a dual-stage purification architecture centered on high-efficiency reverse osmosis (RO), integrated with a modular Progard pre-treatment cartridge. This configuration achieves >95% rejection of dissolved ions, organic contaminants, particulates, and microorganisms—ensuring stable output quality compliant with ISO 3696, ASTM D1193, and CLSI EP21-A guidelines for non-critical laboratory applications. The system operates at a nominal flow rate of 5 L/h (±15%), with pressure-regulated delivery maintained across ambient temperature fluctuations (5–35 °C) via an integrated booster pump. Its closed-loop RO recovery circuit improves water utilization efficiency by up to 50% compared to conventional single-pass systems, reducing both operational cost and environmental footprint.
Key Features
- Integrated high-recovery RO module with automatic membrane flush cycle—minimizes scaling and extends membrane service life
- Modular Progard pre-filtration cartridge (sold separately) containing activated carbon, sediment filter, and ion exchange media for comprehensive feedwater conditioning
- Stable 5 L/h output independent of inlet pressure or temperature variation, enabled by constant-flow pump control and thermal compensation logic
- Backlit LCD interface with intuitive keypad navigation—displays real-time conductivity, system status, maintenance alerts, and cartridge lifetime indicators
- Optional remote display unit for under-bench installation—enables continuous monitoring of resistivity (≤5 µS/cm), temperature, and alarm states without direct line-of-sight access
- RS-232-C serial port supporting GLP-compliant data export to external printers or LIMS; compatible with ExPoreData software for audit-trail-enabled system parameter logging and trend analysis
- UL/cUL listed under E216983 for Laboratory Use Electrical Equipment (UL 61010-1); CE marked per EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU
- Manufactured in ISO 9001:2015 and ISO 14001:2015 certified facilities; design supports future upgrade path to Elix series configurations
Sample Compatibility & Compliance
The RiOs 5 is validated for use with standard municipal tap water meeting WHO Guidelines for Drinking-water Quality and local regulatory limits for total chlorine (<5 mg/L), hardness (<450 mg/L as CaCO₃), and turbidity (<1 NTU). It is not intended for brackish or seawater feed sources. Output water meets ISO 3696:1987 specifications for Type III water: conductivity ≤5 µS/cm at 25 °C, total organic carbon (TOC) <200 ppb, bacteria <10 CFU/mL (without optional UV lamp), and particle count 0.22 µm). When equipped with the 185/254 nm dual-wavelength UV module (optional accessory), bacterial reduction exceeds 4-log₁₀ and TOC is reduced to <10 ppb—enhancing suitability for sensitive cell culture rinse steps or HPLC mobile phase preparation. All electrical and mechanical safety certifications are documented per IEC 61010-1:2010 and traceable to third-party notified bodies.
Software & Data Management
ExPoreData software provides secure, password-protected access to historical system performance data—including daily flow volume, cumulative runtime, conductivity trends, and cartridge replacement timestamps. Data logs comply with FDA 21 CFR Part 11 requirements when deployed with user authentication, electronic signatures, and immutable audit trails. The RS-232 interface supports time-stamped printouts of conductivity readings and maintenance events, fulfilling GLP documentation standards for routine QC verification. No cloud connectivity or proprietary firmware updates are required—configuration remains fully local and IT-administrator controllable.
Applications
- Routine glassware rinsing and autoclave feedwater supply
- Feed source for Milli-Q® ultrapure water systems (e.g., Milli-Q® IQ 7000, Milli-Q® Reference)
- Preparation of buffers, reagents, and standards for qualitative analysis, titration, and spectrophotometry
- Humidifier reservoir filling and steam generator feed in controlled environments
- Non-critical cleaning of lab equipment and surfaces where endotoxin-free water is not mandated
- Supporting ISO/IEC 17025-accredited testing laboratories requiring documented water quality traceability
FAQ
What feedwater quality is required for optimal RiOs 5 performance?
Municipal tap water with free chlorine ≤5 mg/L, hardness ≤450 mg/L as CaCO₃, and turbidity ≤1 NTU is recommended. Pre-installation water analysis is advised for sites with high iron, silica, or sulfate content.
Can the RiOs 5 be connected to a central water distribution loop?
No—it is designed exclusively for point-of-use operation. For centralized distribution, consider the Elix or Symmetry series with dedicated loop-compatible controllers.
Is UV disinfection included by default?
No. The 185/254 nm UV lamp is an optional add-on component, primarily used to suppress microbial regrowth in storage or distribution scenarios.
How often must the Progard cartridge be replaced?
Typical service interval is 6–12 months depending on feedwater quality and daily usage volume; the system displays real-time saturation indicators on the LCD screen.
Does the RiOs 5 support remote monitoring via Ethernet or Wi-Fi?
No. Communication is limited to RS-232 serial interface; networked telemetry requires integration with third-party SCADA or BMS systems via analog signal converters.
