The PURELAB Option Q has been developed by ELGA to produce ultrapure water (type I) without the need to pre-purify the supply. The system can produce up to 20 L/hour (160 L/day) of water at 18,2 MΩcm, directly from a source of drinking water. Recirculating purified water within the DV25 docking vessel or reservoir ensures that the water purity is constantly at its maximum level.

• Microprocessor-controlled system management with continuous water purity monitoring
• Adjustable audio-visual alarms
• Direct access to front inspection doors for easier access to parts
• Cartridge replacement indicator
• RS232 interface enables data collection (GLP-compliant)
• ELGA Biofilter (optional) ensures that the water produced is free from endotoxins, bacteria and nucleases
