4002430 Automatic steam distillation unit Kjeldahl

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 sa- me time as it is produced ( evaluation «On-Line»), the evaluation and distillation are completedasoneoperation, reducingdrastically theanalysis time. This typeofeva- luation offers the following additional advantages: detects the point where the sam- ple no longer produces Nitrogen, which means that, the distillation stops at the opti- mum maximum Nitrogen recovery and does not prolong the analysis longer than necessary. 

The titration is a colorimetric method and is accepted byAOAC and does not require any periodic calibration.

FEATURES 
Distillation by steam generation. 
Automatic «On-line» colorimetric evaluation. 
Steam generator withsafety thermostat,over temperatureandoverpressuredevice. Safety, door closed, that prevents distillation if open. 
Detects thatadigestion/distillationtubeispresent.
Thisprevents thedosingof 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, BoricAcid 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 anABSplastic front.
