Further determinations - Compact system (Sulfuric acids)

Sulfuric acids

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.

Further determinations - Compact system (Water content)

Water content

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.

Available product variants:
Further determinations - Steam generator (Alcohol)


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

Available product variants:
Further determinations - Steam distillation unit (Alcohol / volatile acids)

Alcohol / volatile acids

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.

Available product variants:
Further determinations - Essential oils

Essential oils

The content determination of essential oils takes place in the behrotest devices by means of steam distillation.

The distillate is collected in the measurement tube, which contains xylol. The water is automatically returned to the distillation flask.

Available product variants:
Further determinations - Hydroxyproline


Determining the hydroxyproline content of meat, meat products and sausage products in accordance with Sec. 64 LFGB (German Food & Feed Act). In this process, a sample is subject to acid hydrolysis. Acid hydrolysis can either be completed through a classic process with a behrotest RH 6 digestion apparatus or with a modern behrotest HDP 6/12 digestion apparatus. Then the oxidized hydroxyproline is measured photometrically at 558 nm.
