Purelab Chorus series

ELGA Labwater from UK is an integral part of Veolia Water Technologies, the world leader in water treatment.

ELGA specializes in delivering water purification systems for research, diagnostic, clinical and healthcare environments. ELGA has 75 years experience in water purification technologies. ELGA’s water purification system has unique features like continuous real-time water quality monitoring, recirculation of purified water stored in tanks, customizable audible and visual alarms etc.

Key Features:

Easy operation and control – Real-time continuous display of water quality, auto volume dispense and low water purity and low reservoir alarms at a glance. Red and white light to check the status of the system and consumable life. Front access with easy push-fit connectors for cartridge replacement.
Guaranteed water quality – Customizable audible and visual alarms ensures specific water quality is delivered at all times. Alerts the user when the quality drops below set-point.
Recirculation of purified water – Stored pure water detoriates sharply. Recirculation ensures a consistent peak water purity with a low bacterial specification is fed to the analyser.
A multipurpose pure water system – the integral dispense tap gives you the convenience of drawing pure water for general laboratory applications without compromising the analyser feed.
Guaranteed bacterial specifications – Integrated UV Lamp and optional Biofilter will lower bacterial Endotoxin, DNase, RNase and bacteria count.
Reduced Maintenance Times – Quick and easy replacement of consumables as well as semi-automated sanitization to reduce maintenance times.
Complete System– Inbuilt Delivery pump for direct pressurised feed to analysers. No hidden costs.
Economical operational cost– Extra long life RO membrane. Predictable and long-lasting consumables life.
Space-Saving Design – smallest footprint available in the market for the pure water specification. 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.
Halo Dispenser – Dispense solution can be installed independently from the main unit. Halo dispenser with purity monitoring at the point of use and Auto volume dispense are also available.
Reservoirs – Full range of water storage reservoirs from 15Lts, 30Lts, 60Lts, 100Lts with integrated level sensors, advanced vent filter available.
Focussed and Reliable technical support team who can understand clinical diagnostics.
