Distillation Unit, Automatic
Product code: AG71-402
Distillation unit designed for diversified and flexible use, including applications such as determining ammoniacal nitrogen, protein nitrogen, (Kjeldahl or direct alkaline distillation), nitric nitrogen (after reduction), phenols, volatile fatty acids, cyanides, alcohol content, etc, to official
procedures.
The units come with a patented steam generator that assures distillations are carried out in absolute safety and without routine maintenance. The supply water feed is automatically stopped during pauses, thus cutting down on its consumption. The instrument is equipped with a system that recognises when
the sliding protection door is not closed and when the test tube is not in position, without which the dosing pump does not start operation. Use of an innovative system allows various sizes of test tubes to be used and 500 ml Kjeldahl flasks to be housed. Both units work in accordance with official methods AOAC, EPA, DIN e ISO, with model AG71-400 representing the basic unit, and model AG71-402 the more advanced, semi-automatic unit.
Supplied complete with test tube, flask, tongs and inlet tube.
