The PURELAB Chorus water purification system is an advanced laboratory solution designed to deliver consistently high-quality purified water for scientific applications. This modular system combines sophisticated filtration technology, UV treatment, and precision engineering to produce Type I, II, and III water that meets or exceeds industry standards.
With its intuitive touchscreen interface, flexible dispensing options, and space-efficient design, the PURELAB Chorus enables researchers to maintain experimental integrity while optimizing laboratory workflows.
The system’s real-time monitoring capabilities ensure reliable performance, making it an essential component for facilities conducting sensitive analytical procedures, biological research, and general laboratory operations.
The PURELAB Chorus 2 system works through a multi-stage purification process:
The PURELAB Chorus 3 follows a similar but simplified process:
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.
Prelab Chorus Water Systems are widely used in various industries and laboratories where high-purity water is essential. Some of the key applications include:
High-purity water is essential in laboratories and research facilities, especially for buffer preparation and autoclave processes. The PURELAB Chorus 2 is an excellent solution for this purpose, providing a consistent supply of ultra-pure water.
Its advanced filtration system removes all types of contaminants, which is crucial for the accuracy of buffers and effective sterilization. In autoclave processes, water purity is critical because impure water can leave residues that may affect sterilization.
The PURELAB Chorus 2 ensures that high-quality and contamination-free water is available every time, making it ideal for medical, pharmaceutical, and research applications.
Its user-friendly design and efficient performance enhance laboratory workflows, enabling scientists and technicians to complete their experiments and sterilization processes without interruptions.
Water constitutes the foundation of nearly all laboratory work, serving as:
Any impurities in laboratory water can compromise experimental results, damage instruments, and introduce variables that undermine research integrity.

PURELAB Chorus 3 water is suitable for:
The PURELAB Chorus water system can be easily expanded after installation. Its modular design provides flexibility, allowing new modules or dispensing units to be integrated into the system as needed.
This feature is highly beneficial for laboratories, where the system can be customized and upgraded to meet growing research and operational needs without needing to replace the entire system. In this way, you are prepared for future requirements with ease and cost-effectiveness.
Yes the PURELAB system, the RO (Reverse Osmosis) module plays a critical role in removing impurities from feed water. It efficiently eliminates dissolved salts, particulates, bacteria, and organic contaminants, ensuring high-quality purified water.
The RO module serves as a primary pretreatment stage, preparing the water for advanced purification steps like deionization and UV treatment. This improves the overall efficiency of the system and extends the lifespan of consumables.
PURELAB Chorus 2 & 3 systems accommodate various installation scenarios:
The systems are designed to integrate with laboratory infrastructure:
The modular design of PURELAB Chorus 2 & 3 systems offers significant advantages:
The intuitive control system enhances laboratory efficiency:
Multiple dispensing configurations accommodate diverse laboratory workflows:
The water delivery rate is affected by several factors. The first and foremost factor is feed water pressure; if the pressure is low, the delivery rate may also slow down. The condition of system components, such as filters and RO membranes, directly impacts the delivery rate—clogged or worn-out components reduce the rate.
Flow rate settings and dispenser configurations, such as variable flow control, provide flexibility to adjust the delivery rate. Lastly, environmental conditions, such as temperature, also influence delivery performance, as processing cold water requires more energy.
PURELAB Chorus 2 & 3 systems simplify necessary maintenance:
Reliable operation is ensured through robust support:
The PURELAB Chorus 2 & 3 water purification systems represent essential investments for laboratories seeking to enhance research quality, operational efficiency, and experimental reproducibility. By delivering consistently pure Type II and Type III water, these systems establish the foundation for reliable laboratory procedures across scientific disciplines.
Their modular design, user-friendly interfaces, and economic operation make them ideal solutions for facilities ranging from small research laboratories to large institutional settings.

1. What are the main differences between Type II and Type III water?
Type II water (>10 MΩ-cm) offers higher purity suitable for sensitive applications like media preparation and analytical chemistry, while Type III water (1-10 MΩ-cm) is designed for general laboratory use like glassware rinsing and feed water for higher-grade systems.
2. How often do consumables need replacement?
Consumable replacement intervals vary based on usage volume, feed water quality, and purification requirements. Typically, primary purification cartridges last 6-12 months under normal conditions, with the system providing advance notification when replacement is needed.
3. Can these systems be upgraded as laboratory needs change?
Yes, the modular design allows for various upgrades including additional dispensing options, enhanced monitoring capabilities, and integration with other Chorus units to create comprehensive water purification solutions.
4. What kind of feed water is required?
PURELAB Chorus 2 & 3 systems are designed to accept standard potable tap water meeting basic quality parameters. In areas with particularly challenging water quality, additional pretreatment options are available.
5. How do these systems support compliance with laboratory standards?
The systems provide documented water quality, operational logs, and validation packages that support compliance with various laboratory standards including CLSI, ASTM, ISO, and pharmacopeia specifications for laboratory water.
