Kjeltec™ Distillation Unit
Kjeltec™ 8000 – Kjeldahl Distillation Solutions for Food and Feed

The Kjeltec™ range offers a series of automated distillation units designed primarily for Kjeldahl analysis, but widely used for many different distillation chemistries.
Kjeltec™ features include variable steam output, intelligent cooling water and distillate temperature control, reagent addition, tube emptying and FOSS patented SAfE technology in all models.
A fully automated analyser, Kjeltec™ 8400, with on board self cleaning colorimetric titration system completes the range. Optional Kjeltec™ 8420/8460 Auto Samplers for 20 or 60 samples offer fully unattended operation of the analyser.
