The TitreFAST Range

The TitreFAST high throughput automated analysis system is a versatile automated platform for potentiometric titration demands. Combining cutting edge titration equipment with the Gilson Autosampler range, the TitreFAST provides the perfect solution to the problems of high sample throughput, time pressure, sampling inconsistency and repetitive manual work.

Flexible, fast and high throughput

Applications within the field of titration can be diverse and demanding, The TitreFAST addresses this by providing unmatched flexibility with options for 2 different automation platforms, Dip or static cell measurements and bespoke rack design options. The TitreFAST can be configured to provide a solution to match a customers priority whether it is cost or throughput.

The system allows a capacity of up to 350 15ml test tubes to be automatically analysed with minimal operator involvement and full LIMS communication. Accurate and robost the titreFAST Offers unparalleled automated liquid handling with powerful titration options. 

Key features

  • High throughput TAN, TBN, acidity by potentiometric titration
  • High throughput ISE detection
  • Unrivalled application flexibility with the potential to automate sample preparation in addition to titration ie mixing, sub sampling, dilution.
  • Uses low cost disposable sample tubes
  • Offers fast titration with dynamic focused end point detection for unmatched accuracy
  • Needle wipe to prevent contamination and automated reagent waste removal
