Destilador kjeldahl “PRO-NITRO M”

Steam distillation unit Kjeldahl “Pro-Nitro M”

Determination of organic nitrogen (kjeldahl method).
Automatic naoh dosage and temporize stop.

Steam distillation Kjeldahl unit.
Simple secure systematic analysis suitable for small to Medium throughput of samples. 


Steam distillation system.
Compact steam generator with safety over temperature thermostat and over pressure device.
Safety door, the system will not operate if the door is open.
“Tube in place” sensor: if the tube is not located, the dosing process of NaOH will not take place.
Universal adapter for digestion/distillation tubes MACRO (Ø 42 mm) and MICRO (Ø 26mm)
Small footprint, saves bench top space: The H2O and NaOH reservoirs are placed within the unit.
Stainless steel case with reinforced ABS plastic front.
Automatic distillate titration kit. (See accessories). 


Measuring range: from 0.2 to 200 mg of Kjeldahl Nitrogen. Programmable distillation time.
Nitrogen recovery >99.5%
Distillation speed: from 35-40ml/minute
Typical distillation time: from 7-10 minutes.
Water consumption rate: from 80-100 litres/Hr.
Steam generator water consumption: 2,5 Litres/ Hr.
Water reservoir for steam generator: 6 litres
NaOH reservoir: 2 Litres. 


Low water level for the steam generator.
Safety door open or no distillation/digestion tube in place.
Steam generator over temperature. 


Open and closure of cooling water to the cooling coil.
Automatic load of NaOH once the distillation has started.
Select NaOH volume.
Stop at the end of the pre-set programmed time. 


To complete Kjeldahl Nitrogen analysis a digestion block is also required.
