Range of applications

  • Steam volatile compounds such as alcohol, TVBN, volatile acids or phenols are separated best by gentle distillation under reduced steam power.
  • Nitrates or nitrites are conveniently reduced in-situ using programmable optional reaction steps.
  • Automated dosage of strong acids such as phosphoric acid directly into the distillation tube yields exhaustive distillation of SO2 or formaldehyde.

Convenient and reproducible

  • 50 personalized methods for various sample matrices featuring steam regulation, reduction and dosage of strong acids. Ready-to-use BUCHI approved Application Notes guarantee reproducible operation.
  • Communication with a wide variety of titrators reduces manual operation, enables documentation and LIMS integration.
  • Prevention of carry-over even of strongly foaming samples thanks to the dedicated Devarda splash protector.

Flexible and safe

  • Quick and easy switch between Kjeldahl and direct distillation without laborious reconnection of chemical tanks.
  • No manual addition of harmful chemicals. Automated cooling media control.
