This instrument is designed for the extraction of volatile acids or sorbic acid, by a steam generator. It is equipped with a highly resistant aluminum steam generator (no container of boiling water). The high-power heater (2800 W) generates steam by injection with a dosage pump during the entire extraction process. Can be used for all types of wines, liquors, musts, even when they contain sugars or solid fragments.
A pyrex glass bubbler with a non-return bulb allows the extraction without increasing the initial volume of the sample, and the total release of volatile acids. A rectifying column with Raschig rings prevents the distillation of the lactic acid. The end of the extraction, depending on the chosen time, is immediately obtained thanks to the stop of the pump that supplies the generator with water.
The use of Graham cooling coils (external diameter: 44mm, length: 450mm and length of the enrolled coil 2.50m) ensures a total condensation of the distillates. An electric electrovalve managed by the electronic timer ensures the automatic closing of the cooling circulation between distillations.
