Mixed Indicator for Sulphur SO2 Determination

A mixed indicator used in sulphur dioxide determination, part of the laboratory side of winemaking. Reagents like this belong to the titration work winemakers do when they want a number rather than a guess about the free SO2 in a wine. We stock it for the home and small scale producers who run their own bench tests, and for anyone restocking a lab kit at the start of vintage. Made in Australia. Read the label and follow the manufacturer's own guidance for this product. If you are not certain this is the reagent your method calls for, check your procedure before ordering.
