NEW
A high precision balance is weighing the right quantity of iodine.
100 g mass is supplied for the calibration.

BUBBLE
To determine the free sulphur dioxide in red and very red wines and musts.
It allows extraction and bonding of the free sulphurous dioxide from wine into a water, colourless solution which can then be titrated with SO2Gravimeter.
It also allows for a indication to be made of the presence of ascorbic acid based on the difference between the titration on wine and that on wine after treatment with Bubble.
