Determination of SO2 in food, especially grain. By adding hydrochloric acid, the SO2 is moved out of the sample and absorbed in the behrotest absorption vessel perhydrole (H2O2). H2O2 is boiled and the solution titrated.

Function: The determination takes place through azeotropic distillation. For this, various sample materials xylene or toluene is added. In the vaporous phases the solvent binds with the water and after condensation, the water is separated from the solvent in a measuring tube.

Flexible distillation device that is ready for operation after no more than 30 seconds.

There are two devices that can be used for the determination of alcohol: D1 & D2, whereby distillation for D1 takes place in the pycnometer and distillation for the D2 in the Erlenmeyer flask.

The method for the determination of vitamin A and vitamin E in foodstuffs is effected in accordance with DIN EN 12823-1 and DIN EN 12822.

The method for the determination of saponification value in animal and vegetable fats and oils is effected in accordance with DIN EN ISO 3657. With an excess of ethanolic potassium hydroxide solution the tested sample is saponified by boiling under reflux and later titrated with standard hydrochloric acid solution until reaching the end point.
