Available Models

PURELAB Chorus 2+ (RO/EDI/UV) features our patented recirculating EDI technology: the only EDI system on the market that is able to fully recirculate to maintain >15 MΩ.cm.

  • Fully Recirculating EDI  ELGA’s patented fully recirculated EDI provides a constant supply of high purity that guarantees a minimum of 15 MΩ.cm water at all times.
  • Ideal for High Volume Labs  A cost-effective solution for laboratories requiring higher output volumes thanks to the incorporated EDI technology.
  • Single System Solution  Perfect single system solution for analytical and life science applications requiring >15 MΩ.cm.
  • Reduced Maintenance Times Quick and easy replacement of consumables to reduce maintenance times.
  • Space Saving Design  Designed to be modular and stackable to save space, whether wall-mounted or under the bench.
  • Data Capture Data capture via USB for system performance validation and software updates.

Ideally suited for: Electrochemistry, Cell cultures, Spectrophotometry, Feed to ultrapure water, Media/buffer preparation, General chemistry

● Type II+ Water  ● >15 MΩ.cm  ● Liters per day: 1 – 120

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.

  • 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.

Ideally suited for: Electrochemistry, Spectrophotometry, Feed to ultrapure water, Media/buffer preparation, General chemistry

● Type II+ Water  ● >15 MΩ.cm  ● Liters per day: 1 – 100
