ELGA water purification system PURELAB Chorus 3 (RO)
The ELGA water purification system PURELAB Chorus 3 (RO) reliably supplies type 3 pure water from drinking water in the most compact form, allowing flexible supply for a wide range of laboratory applications. Conventional devices on the market are often bulkier and require more maintenance steps, whereas this system focuses on space-saving installation options and the automatic rinsing function. Similar features to the [ELGA water treatment system PURELAB Chorus 2] offer further options in terms of performance and expansion level if, for example, a combined application is required.
Powerful treatment and flexible configuration
This unit is designed for smooth operation: it can be placed under the laboratory bench, on the wall or on a table. With its modular design, the pure water output can be upgraded from 10 to 20 or 30 liters per hour as required. It can also be combined with other Chorus 3-DI or Chorus 2-RO/DI systems to achieve higher flow rates in particularly water-intensive laboratory environments.
The built-in reverse osmosis unit with a retention rate of over 95% for inorganic substances and more than 99% for organic substances (>200 Da) is particularly advantageous. This ensures reliable pure water quality, which is crucial for the preparation of buffer solutions, media or for general rinsing tasks in the laboratory. The color display is clearly laid out and provides information on tank fill level, pure water quality and temperature, among other things. If required, alarm values for product water quality (20, 50 or 100 MΩ-cm) and temperature (30, 35 or 40 °C) can be individually adjusted.
Important technical parameters (key points in abbreviated form):
- Production capacity: 10, 20 or 30 l/h (depending on module)
- Retention rate for inorganic substances: >95 %
- Retention rate for organic substances (>200 Da): >99 %
- TOC content: <50 ppb
- Bacteria content: <5 CFU/ml
- Operating temperature range: 1-35 °C
- Noise level: <40 dBA
Other parameters such as pH value (close to neutral), feed water pressure (between 0.5 and 6.0 bar, depending on the version) and the maximum concentrations for free chlorine compounds or heavy metals show how nuanced the system can be tailored to the requirements of different laboratory infrastructures.
Thanks to automatic flushing mechanisms, the system remains hygienically clean, minimizing maintenance and downtime. For even better integration into the existing laboratory environment, the device can be supplemented with a suitable PURELAB Chorus storage tank. This ensures continuous availability even when large quantities of water are required. The modular concept also enables expansion without having to replace the entire system.
Certifications and standards
The device complies with typical laboratory standards and fulfills all quality and safety regulations required in laboratory environments, which usually includes CE marking. In addition, many laboratories integrate the system into their ISO 9001-certified quality management processes, enabling traceability and standardization of water quality.
Concrete application examples
- Preparation of buffer and culture media in research, analytical and routine laboratories, where freedom from contamination pays off thanks to low bacteria levels (<5 CFU/ml)
- Pre-treatment of water for autoclaves and automatic cleaning machines that require reliable minimization of streaks or streaks after rinsing.
- Supply of technical devices (e.g. spectrophotometers or elemental analyzers) that benefit from high purity and consistent water quality.
- Integration into laboratory processes that value reproducible results (e.g. pH-sensitive applications, cell culture or microbiological tests)
FAQ
What maintenance work is required on a regular basis?
As a rule, this involves the timely replacement of pre-treatment cartridges and RO modules to ensure high water quality. The automatic flushing function prevents deposits and reduces maintenance work.
Is a special installation required
The system can be installed on the wall, underneath or on a table. Only the feed water pressure needs to be checked and, if necessary, regulated using accessories (pressure reducer)
Can several appliances be linked?
Yes, up to four Chorus 3 or Chorus 2 systems can be combined with each other. This allows larger laboratories with high pure water requirements to be served effectively.
What are the specific advantages of the color display?
The color display makes it easier to monitor the water status: it shows conductivity, fill level and important alarms, among other things. The alarm values for temperature and conductivity can be adjusted, which increases process reliability.
Can this system provide different qualities of pure water at the same time?
The model is specially designed for type 3 pure water. If you want to use different qualities of pure water at the same time, additional modules or combined systems from the same Chorus series are recommended.
Conclusion
This compact, performance-oriented system is a flexible, upgradeable laboratory solution. With reliable reverse osmosis, optional networking options and an intuitive display, it meets a wide range of water preparation requirements in the laboratory. Thanks to its modular design and compatible storage and add-on options, it adapts to individual requirements, ensuring consistent, high-quality water for many applications.
