Jedinica destilacije pare Kjeldal poluautomatska “Pro-Nitro S”, Selecta

ODREĐIVANJE ORGANSKOG AZOTA (KJELDAL METODA).
Semi-automatic steam distillation Kjeldahl unit. Simple secure systematic analysis
suitable for medium to large throughput of samples.
FEATURES
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 42mm) and MICRO (Ø 26 mm).
Small footprint, saves bench top space: The H2O, NaOH and H3BO3reservoirs areplaced within the unit.
Empty Digestion/ Distillation tube system.
Stainless steel case with reinforced ABS plastic front.
Green LED 2 digit display.
Distillation program: (Add NaOH, Add Boric Acid, Distillation time, Empty tube.)
Automatic distillate titration kit. (See accessories).
SPECIFICATIONS
Measuring range: from 0.2 to 200 mg 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.
Boric Acid reservoir: 2 Litres
ALARMS
Low water level for the steam generator.
Safety door open or no distillation/digestion tube in place.
Steam generator over temperature.
AUTOMATIC
Single push button to start the distillation cycle:
– Boric acid dosing
– Start distillation.
– NaOH dosing
– Stop Distillation (Programmed time transpired.)
– Acoustic indicator at the end of the cycle.
ADDITIONAL REQUIREMENTS
To complete Kjeldahl Nitrogen analysis a digestion block is also required. (See Bloc Digest pages 251and 252).
