Titrets Free SO2 Tester - Box of 10

Titrets testers for monitoring Free SO2 levels in wines. The Sulfite in Wine Titrets test is based on the �Ripper� chemistry which employs an iodide-iodate titrant in an acid solution and a starch indicator2,3,4. The �Ripper� chemistry is used as a screening method throughout the winemaking industry for determining the sulfite content in wines. Results are expressed as free SO2. Results for this test kit are acceptable for dry white wines although they can have an error of up to 10 ppm. This test kit is not recommended for use with red wines or white wines containing ascorbic acid or tannin. These wines often give false high test results. As a rule, a test result of greater than 40 ppm free sulfite for any wine should be considered suspect and an alternative sulfite determination method should be employed. Pack of 10 test vials and plastic tubes. Instructions: 1. Collect the sample in any clean container. 2. Push a valve assembly onto the Titret ampoule tip until it fits snugly. NOT
