How PURELAB Chorus 2 and PURELAB Chorus 3 Work
PURELAB Chorus 2 Operation
The PURELAB Chorus 2 system works through a multi-stage purification process:
Pre-Treatment Stage:
- Water first passes through pre-filters that remove larger particles, chlorine, and organic contaminants
- This protects downstream components and extends their lifespan
Primary Purification:
- Uses ion exchange technology via specialized purification cartridges
- Removes dissolved minerals, salts, and ionic contaminants
- Achieves Type II water quality (typically >10 MΩ-cm resistivity)
Recirculation System:
- Constantly circulates water through the purification path
- Maintains water quality even during periods of non-use
- Prevents bacterial growth and contamination
Dispensing System:
- Variable flow rate controls for precise dispensing
- Optional point-of-use filters for final polishing
- Provides Type II water suitable for general laboratory applications.
PURELAB Chorus 3 Operation
The PURELAB Chorus 3 follows a similar but simplified process:
Filtration:
- Removes particulates and contaminants from feed water
- Uses composite filters tailored to local water conditions
Deionization:
- Less intensive ion exchange process than Chorus 2
- Produces Type III water (typically 1-10 MΩ-cm resistivity)
- Suitable for non-critical applications like glassware rinsing
Storage and Dispensing:
- Optional reservoir system for storing purified water
- Basic dispensing controls for laboratory use
- Economical solution for general laboratory needs.
What types of lab water does the system produce?
PURELAB Chorus systems produce three main types of laboratory water: Type I (ultrapure) water with 18.2 MΩ-cm resistivity for critical analytical applications, Type II water with typically >10 MΩ-cm resistivity for general lab applications like media preparation and buffer solutions, and Type III water (1-10 MΩ-cm) for basic laboratory needs like glassware rinsing and water baths.
The specific model determines which water types are available - Chorus 1 produces Type I, Chorus 2 delivers Type II, and Chorus 3 provides Type III water, with each type meeting international laboratory water standards for their respective applications.
