DETERMINATION OF ORGANIC NITROGEN (KJELDAHL METHOD) FULLY AUTOMATIC OPERATION.
FROM THE REAGENT DOSAGE TO THE TITRATION.
Steam distillation system Kjeldahl, complete with automated “ON-LINE” analysis (evaluation in real time). For systematic precise analysis, with minimum personnel intervention, simple and safe. Adequate for a laboratory with a medium to large throughput of samples. The Kjeldahl steam distillation unit «PRO-NITRO A» evaluates the distillate at the same time as it is produced ( evaluation «On-Line»), the evaluation and distillation are completed as one operation, reducing drastically the analysis time. This type of evaluation offers the following additional advantages: detects the point where the sample no longer produces Nitrogen, which means that, the distillation stops at the optimum maximum Nitrogen recovery and does not prolong the analysis longer than necessary.
FEATURES
Distillation by steam generation.
Automatic «On-line» colorimetric evaluation.
Steam generator with safety thermostat, over temperature and over pressure device.
Safety, door closed, that prevents distillation if open.
Detects that a digestion/distillation tube is present. This prevents the dosing of NaOH if there is no tube located.
Universal adapter for MACRO (Ø 42 mm) and MICRO (Ø 26 mm)distillation tubes.
Space saving in the laboratory: the reservoirs for the H2O, NaOH, Boric Acid and HCl are located inside the unit.
Empties the digestion/distillation tubes and the collector automatically. Automatic stop when distillation is complete.
Large LCD display of 20 x 4 characters. RS232 output to results printer. Main system made from stainless steel with an ABS plastic front.
