Titrets Sulfite Testing Kit - Box of 10
Contains 10 tests per box. This sulfite testing kit is ideal for white wines in the range of 10 - 100 mg/L. This will test your free SO2 levels so that you can adjust acordingly before transfers and before pitching yeast. This test kit is based on the Ripper method, used in the wine industry for years for rapid sulfite analysis. The sulfite is titrated with an iodide-iodate solution, using a starch end point indicator. Phosphoric acid is used to adjust the pH of the sample.
The results are quantified using direct-reading titration cells. The test determines free sulfite as ppm (mg/L) SO2. This test kit is ideal for white wines, although keep in mind that there can be an error up to 10 ppm. This test kit is not recommended for red wine, or white wine containing ascorbic acid or tannins, which can result in false high test results.
