Total Sulfur Dioxide 30 Test Kit

Sulfur dioxide is used as a preservative in wine and there are restrictions limiting the amount that can be added in most wine producing countries. This test kit is a fast and easy way to determine the amount of total sulfur dioxide in wine samples, without the need for the laborious setup associated with traditional methods.

For this Test Kit semi-micro cuvettes are required.

The amount of sulfite present in wine is measured by monitoring the reaction with a chromogen under basic conditions. The reduction of the chromogen leads to formation of a strongly absorbing compound which can be measured at 340 nm. The measured amount of the activated chromogen is stoichiometrically proportional to the amount of total sulphite present.
