for volatile acidity in wine
This instrument is used to determine the content of volatile acidity, made up of fatty acids belonging to the free or salified acetic series. Its titration enables monitoring of the composition of the wine while it is being made and to avoid volatile acidity produced by lactic and acetic acid bacteria.
Composition of the apparatus:
- a 2-litre vapour–generating bulb
- a scrubbing flask
- a condenser
- an extraction column
There are 3 different models.
The ACV1: the most simple. The different parts are connected by rubber tubes, and the apparatus is heated by gas (Bunsen burner). The cocks are made of glass.
The ACV2: More compact owing to the spherical connections, it is also more efficient than the ACV1. Also heated by gas, it is characterised by the addition of a second burner under the scrubbing flask.
The ACV3: identical is to the ACV2 but heated electrically using a boiler fitted with two 500W resistors.
