  • Optional ELGA Biofilter - when fitted to the Option-Q produces water which is free from biologically active impurities. This makes it suitable for use with applications which require endotoxin free ultrapure water, bacteria-free water, and nuclease-free ultrapure water
  • Type III / RO water available from the reservoir
  • Front-entry service doors for easy and quick access to consumables
  • Data collection capabilities through RS232 interface – for compliance with GLP guidelines
  • Perfect single system solution for analytical and life science applications
  • Delivers up to 15 liters an hour of type I water
  • Up to 18.2 MΩ-cm, type I water suitable for critical applications
  • Easy to maintain
  • Produces type I water directly from tap water
  • Full service and validation support
