Duo-i-III.I
Manufacturer – Avidity
Description: Duo-i III.I is a fully integrated reverse-osmosis (RO) + ultrapure water system that can generate lab-grade water directly from tap water. It can produce both Type III pure water and Type I ultrapure water, dispensing them on demand through a flexible dispenser — providing a dual-quality water solution from a single footprint.
Key Features & Specifications:
• Dual-quality water output: produces Type III (RO) water and Type I (ultrapure, 18.2 MΩ·cm) water from the same unit.
• High flow & output rate: up to 30 L/hr of Type III water (depending on model) and dispense rate ≥ 2 L/min for both Type III and Type I water.
• Water quality: Type III output conductivity < 5 µS/cm; Type I ultrapure water resistivity 18.2 MΩ·cm. Bacterial load < 0.01 CFU/mL.
• Advanced purification technology: “Twin-pass” RO for efficient pre-purification.
• User-friendly & safe: interactive 7″ touchscreen; cartridge traceability (data-tagged), option for auto-reservoir sanitisation; flexible adjustable dispensing stations; data capture & printable logs.
• Compact lab-friendly design: reasonably sized (system footprint ~ 575 × 366 × 492 mm) and relatively lightweight for its capacity.
Applications:
Because of its dual output (Type III + Type I), the Duo-i III.I is versatile for multiple laboratory workflows:
• Feed-water for ultrapure systems, glasswashers, autoclaves, steam generators, and general lab utilities.
• Routine lab tasks such as buffer/media preparation, reagent dilution, glassware cleaning, general chemistry and sample prep (using Type III).
• High-purity demanding applications — molecular biology, cell/tissue culture, electrophoresis, HPLC, sequencing, genomics, proteomics, analytical instrumentation — when using the Type I ultrapure output.
