ELGA PURELAB Quest – Compact 3-in-1 Lab Water Purification System (Refurbished)

The PURELAB Quest by ELGA is a versatile laboratory water purification system that provides three quality grades of water—Type I (ultrapure), Type II (pure) and Type III (RO-permeate)—from a single input feed. The system features fast dispense rates, intuitive operation, IoT connectivity and compact design for space-constrained labs. 

Key Features

• Supplies three water grades: Type I, Type II and Type III in one system.
• Rapid dispensing: up to ~1.2 L/min. 
• Compact footprint: width approx. 232 mm, height ~510 mm; wall-mountable to free bench space. 
• Smart monitoring & connectivity: IoT-enabled remote monitoring, USB data export, real-time purity sensors. 
• Sustainable construction: >85% reclaimed materials, long-life consumables. 

Technical Specifications

For Type I (Ultrapure) water:

• Resistivity: 18.2 MΩ·cm @ 25 °C 
• TOC (Quest UV version): <5 ppb
• Bacterial TVC: <0.1 cfu/mL when point-of-use filters used 
• Dispense flow rate: up to 1.2 L/min 

For Type II (Pure) water:

• Resistivity: >1 MΩ·cm @ 25 °C
• TOC: <50 ppb 
• Bacterial TVC: <100 cfu/mL 

For Type III (RO-permeate) water:

• Conductivity: <20 μS/cm 
• TOC: <200 ppb 
• Bacterial TVC: <1000 cfu/mL 

General specifications:

• Recommended maximum daily withdrawal: Type I/II up to ~10 L/day; Type III up to ~30 L/day. 
• Feed water conductivity: ≤2000 µS/cm (higher conductivity may reduce consumable lifetime) 
• Dimensions (W × H × D): approx. 232 mm × 510 mm × ~421 mm 
• Mounting: Bench or wall-mountable unit. 

Applications

The PURELAB Quest is suitable for a wide range of laboratory applications including:

• Ultrapure water for HPLC, GC-MS, ICP-OES, molecular biology workflows
• Pure water for reagent & buffer preparation, general chemistry, histology
• RO-permeate water for glassware rinsing, autoclave feed, and preliminary feed to Type I systems
