PURELAB® flex & 6 

A unique automated solution for Ion Chromatography. Switch on and walk away, Ion Chromatography made easy. 

A standalone Ion Chromatography and water purification system all-in-one. The PURELAB flex 5 & flex 6 is designed to couple directly with the Metrohm 941 Eluent Production Module. This combination delivers complete automation. No need to monitor eluent concentration make-up, no need to refill or to set reminders to refill the water. 

This unique Ion Chromatography solution is produced by two of the world’s leading manufacturers: Metrohm, market leader titration and voltammetry and a leading manufacturer for Ion Chromatography and ELGA®, the market leader in innovation and design for laboratory water instruments. 

  • Integral built-in reservoir for pressureless ultrapure water supply - developed for Metrohm Dosino technology 
  • Closed system avoids eluent contamination due to water handling and exposure 
  • Monitor water purity via USB datalog ensuring analytical performance during test batch 
  • Prevent column clogging and increases column life: UV (185/254 nm) ensures bacteria and organics control 
  • Stable retention times: no dissolved CO2 in water prevents pH change 
  • Enhanced detection limits through improved stability and purity 
  • Simultaneous multi-usage: eluent generation, system rinsing and general laboratory work 
  • Reduces eluent preparation to minimum compared to using bottled water
