Distillation Unit
The Kjeldahl distillation unit is used to perform nitrogen analysis and protein determination by Kjeldahl method in food, feed, environmental and chemical industries after digested the sample accurately. Operations:
  • Check the distilled water level in the steam generator (11)
  • Start the cooling water circulation in the condenser (3)
  • Dilute the digested sample with distilled water (10-20ml) and load it into the inner glass tube (8) through the dropping funnel (1)
  • Take 25 ml of boric acid solution with indicator in 250 ml conical flask and place it at the receiver end (7)
  • Take 40 ml on 40% alkali and keep it ready in the dropping funnel (1) with stop cock closed.
  • Check to as certain that all the rubber tubing is tightly fitted.
  • Now start the steam generator by switching ON the heater
  • The steam generator will now generates steam which passes through the outer jacket tube (9) and then bubble into the inner tube (8) which holds the sample.
  • When the steam bubbles vigorously with the digested sample add 40 ml of alkali “immediately” and close the stopcock.
  • Now the digested sample in the inner tube (8) turns dark brown.
  • Continue the steam distillation until liquid ammonia collects in the boric acid solution. There will be a color change based on the indicator used. Usually it will be red to green. Collect 100-120ml distillate in the conical flask.
  • Switch off the heater and then remove the conical flask and titrate the solution using burette.
  • Now stop the cooling water circulation in the condenser
  • Once the heater is switched off, the digested sample automatically gets siphoned into the outer jacket (9)through the siphoning tube (8)
  • Add distilled water once or twice to rinse and remove the spent reagent which might be present in the inner tube.
  • The spent reagents which gets collected in the outer jacket tube (9) can later be removed by open the pinch – cock and the next experiment can be started. Normally it takes 5 to 7 minutes for distillation of sample.
