Millipore Elix Advantage Pure Water System

Overview

The Millipore Elix Advantage Pure Water System is an engineered solution for laboratories requiring a continuous, reliable supply of high-purity Type II water—defined by ASTM D1193 (Type II), ISO 3696 (Grade 2), and pharmacopeial standards (USP, EP, JP) for purified water. It operates on a multi-stage purification architecture integrating pretreatment (Progard cartridge filtration), high-rejection reverse osmosis (RO), electrodeionization (Elix patented continuous current-driven ion exchange), and optional terminal polishing (Millipak Express 0.22 µm sterilizing-grade membrane or Biopak ultrafiltration). Unlike distillation-based systems, the Elix Advantage delivers consistent resistivity >5 MΩ·cm at 25 °C and TOC <30 ppb without phase change, thermal degradation, or chemical regeneration—making it suitable for routine analytical, preparative, and diagnostic applications where reproducibility, low operational burden, and environmental compliance are critical.

Key Features

• Patented Elix electrodeionization technology: Enables continuous removal of ions without chemical regeneration or downtime; maintains stable resistivity >5 MΩ·cm across variable flow rates and feed water fluctuations.
• Integrated Progard pre-filtration and high-efficiency RO membrane: Reduces scaling, chlorine, organics, and particulates prior to Elix module—extending service life and ensuring robust performance with municipal or well water sources.
• 254 nm UV oxidation stage: Photolytically degrades trace organic contaminants and controls microbial regrowth in the purified water loop.
• Modular E-POD dispensing system: Supports up to three independently installed, pressure-fed E-POD outlets per system—enabling flexible point-of-use delivery across benchtops, hoods, or integrated instruments without loss of water quality.
• Low environmental footprint: Consumes approximately 1/200 the energy of conventional glass distillers; achieves up to 75% RO recovery; certified under ISO 14001 at manufacturing sites; minimizes single-use consumables via long-life Elix cartridges and reusable housings.
• No acid/base regeneration required: Eliminates handling hazards, waste neutralization steps, and associated regulatory reporting burdens typical of mixed-bed deionization systems.

Sample Compatibility & Compliance

The Elix Advantage produces water compliant with globally recognized specifications for purified water, including ISO 3696 Grade 2, ASTM D1193 Type II (resistivity and TOC criteria), and pharmacopeial monographs (USP , EP 2.2.43, JP XVI). When equipped with a Millipak Express 0.22 µm filter or Biopak ultrafilter, output meets stringent microbiological and endotoxin limits required for cell culture media preparation, buffer formulation, and diagnostic reagent manufacturing. The system supports GLP and GMP-aligned workflows through configurable audit trails (via optional software integration), user access control, and documented maintenance logs. All wetted materials comply with USP Class VI biocompatibility and FDA 21 CFR 177.2600 for food-contact polymers.

Software & Data Management

While the base Elix Advantage operates via intuitive front-panel controls, optional connectivity modules enable integration into laboratory informatics environments. System status—including resistivity, TOC, UV lamp intensity, cartridge saturation indicators, and E-POD usage logs—can be exported via RS232 or Ethernet to LIMS or centralized monitoring platforms. For regulated environments, optional data integrity packages support 21 CFR Part 11-compliant electronic signatures, change control, and immutable audit trails. Calibration and maintenance events are timestamped and user-attributed, facilitating internal audits and external inspections under ISO/IEC 17025 or Annex 11 requirements.

Applications

• Preparation of microbiological growth media, PBS, Tris-HCl, and other routine buffers.
• Feed water for Milli-Q® ultrapure systems—reducing upstream load and extending final polishing cartridge life.
• Supply for automated analyzers: clinical chemistry platforms, immunoassay instruments, and hematology systems.
• Humidification and environmental chamber operation (e.g., stability testing, incubators, climate-controlled aging units).
• Hydrogen generator feed water, where low conductivity and minimal silica prevent catalyst fouling.
• Agricultural and hydroponic research requiring reproducible nutrient solution bases free from heavy metals and organics.
• General lab cleaning protocols, glassware rinsing, and equipment feed water where distilled water is over-specified.

FAQ

What is the maximum recommended daily output volume?
The Elix Advantage is scalable: standard configurations support 5–100 L/h continuous production, with total daily capacity dependent on feed water quality, ambient temperature, and RO recovery settings. Peak demand is managed via integrated storage tanks (optional) and pressure-regulated E-POD delivery.
Can the system be validated for GMP use?
Yes—full IQ/OQ documentation packages are available, including test protocols for resistivity, TOC, microbial retention, and alarm response verification. Optional PQ support aligns with ISO 9001 and Annex 15 guidelines.
Is TOC monitoring built-in or external?
The base system includes real-time resistivity and temperature compensation; TOC measurement requires an external online TOC analyzer (e.g., Millipore Sigma TOC-5000 series) connected via analog or digital interface.
How often must the Elix cartridge be replaced?
Typical service life is 6–12 months depending on feed water hardness, silica, and total dissolved solids; system alerts notify users when ion exchange capacity approaches exhaustion.
Does the system require a dedicated drain or ventilation?
No dedicated ventilation is needed; the unit operates at ambient temperature and generates no hazardous vapors. A standard floor drain is recommended for RO concentrate disposal and emergency overflow protection.
