Started by a chemist and winemaker who wanted a simple and inexpensive way to test their grapes. Accuvin tests are designed to be easy for anyone to use and provide real time results giving actionable results. Since 1999 all Accuvin products have been made in America 8 Low Range (0 - 40 ppm) and 2 High Range (40 - 130 ppm) Tests This test solely measures FREE sulfur dioxide. Total sulfur dioxide present in must and wine is not as useful as a preservative as just free sulfur dioxide, as total SO2 is equal to free + bound. The portion of total SO2 that is bound to other chemical components has reduced effectiveness by 30 - 70% therefore free SO2 is much more useful for winemaking. Also, the degree of binding can change over time, affecting the ability of an adequate dose to continue providing its preservative properties. Can be used for both red and white wines, and require NO adjustments or pretreatments. The test formula has been adjusted to accommodate colored samples Get an accurate measurement of FREE sulfur dioxide, something critical to make sure your wine will be stable enabling proper aging Total sulfur dioxide present in must and wine is not as useful as a preservative as just free sulfur dioxide, as total SO2 is equal to free + bound. THIS TEST ONLY MEASURES FREE SO2. No instrumentation or equipment needed for accurate results - just what comes in the package No sample prep required, enabling you to get actionable results in a matter of minutes! The effectiveness of sulfur dioxide as a preservative is also pH-dependent, with low pH wines requiring lower levels, and high pH wines requiring significantly greater concentrations to achieve the same effectiveness as in a typical wine with a pH of 3.3 - 3.4. The Accuvin Free SO2 test kit contains both Low Range (0-40 ppm) and High Range (40-130 ppm) tests. Each test kit contains the number of tests, tubes with rehydration solution, and samplers that correspond to the size of the kit. (All kits contain a ratio of 1:4 high range to low range tests.) Designed by winemakers for winemakers The pigments in red grapes can prevent accurate testing with colorimetric methods, our product's unique design enables the accurate testing of all grapes and enables winemakers to have their own little wine lab in the palm of their hands! Review: Forget this Free SO2 test kit for red wine like Syrah. - I love Accuvin's TA and Malic Acid tests and can corroborate values with other tests/methods; however, not this free SO2 test. The end point colors against the range are not specific and confusing. I've tried high and low range and they don't correlate with other test kits even one I sent to a wine lab. Sorry to be holder of bad news but at least for red wine (late harvest syrah this test kit is useless. Review: Accuvin Free Sulfur Dioxide (SO2) Test Kit for wine, must & Juice analysis.
