• Media / buffer preparation • General chemistry • Feed to ultrapure water Flexible. Configurable. Simple. One complete solution for the laboratory PURELAB Chorus 2+ (RO/DI/UV) provides tap to 15 MΩ.cm pure water for laboratories requiring up to 100 liters per day and is able to fully recirculate to maintain 15 MΩ.cm. The PURELAB Chorus 2+ provides additional bacteria and inorganic quality for sensitive analytical and life science applications above that of basic laboratory work. With its simple design and ease of use, water can be dispensed from the system or from a choice of additional Halo Dispensers. Fully Recirculating In addition to simple composite vent filtration, the PURELAB Chorus 2+ is the only fully recirculating Type II+ pure water system on the market, maintaining consistent peak water purity at 15MΩ.cm. Configuration Ability to configure multiple systems to increase flow rate and save space through stackable solutions that can be wall mounted, on or under the bench. Simplicity Simple to install, operate and maintain, with a clear indication of water purity. It is also simple to replace consumables, reducing maintenance time. Data Capture Data capture via USB for system performance validation and software updates. Dispense Choose from three different Halo Dispense solutions to allow additional dispense points, even in adjacent labs.

Halo Dispense Solutions The modular nature of PURELAB Chorus 2+ means that your dispense solutions sit independently from the unit. You can even have the Halo Dispenser installed in an adjacent laboratory. With Halo Dispenser you have the ultimate flexibility. Clear Display Prioritized information displayed at all times (system status, alarm) for absolute confidence as you dispense. Halo Dispenser Multiple Positioning Position the dispenser independent from the water purification system. Optimize your lab space.
