SO2 Test Kit & Machines

The Ultimate Winemaker’s Companion! Includes everything you need to analyze SO2, pH, and TA in one kit Tests take less than 2 minutes to perform and are incredibly accurate with pH readings to 1/100 of a point Combines the SO2 detection of the SC-100A and the pH/TA analysis of the SC-200 into one compact instrument Audible buzzer and indicator light alert you to when the test is complete Affordable wine analysis averaging roughly $1 per test One lean, mean wine analyzing machine. The SC-300 combines the SO2 detection of the SC-100A and the pH/TA analysis of the SC-200 into one power-packed instrument. It’s built on the same hardware and software as our other two analyzers, so the accuracy is superb. And it’s just as easy to use – The audible buzzer and visual stop light will automatically let you know when you’re tests are done! Because it does not rely on a color change, the SC-300 eliminates the guesswork in Ripper sulfite tests, especially in red wines! Why Choose Vinmetrica’s SC-300? Where else will you find a single, compact instrument that can measure sulfite (SO2), pH and TA (Titratable Acidity) levels throughout the fermentation and aging process? Even in Red Wines! It’s Accurate: SO2: ± 2 ppm Free SO2. TA: ± 0.2 g/L Tartaric acid pH: better than ± 0.02 pH units Quick! – Less than 2 minutes per test! Affordable – About a $1 per test!* Easy to Use – No mystery solutions, pumps or tubing. *SO2 (Sulfite) Tests cost approximately 70¢ / Test (the cost of the reagents per test). If you do a combined pH and TA analysis, the cost of reagents for the pH/TA test is approximately $1.12 / Test. Complete Wine Testing Kit – Includes Everything Needed to Analyze Sulfite (SO2), pH and TA (Titratable Acidity) levels in Your Wines & Musts: SO2 reagents pH/TA reagents Two titration beakers Two 5 mL syringes Two transfer pipettes SO2 electrode pH electrode 25 mL sampling pipette (for SO2) 5 mL sampling pipette (for pH/TA) The SC-300 Operating Manual The SC-300 analyzer gives accurate SO2, pH and TA values. Kit includes everything to perform about 50 sulfite tests and 30 TA tests: both electrodes, all reagents, pipettes, syringe and beaker. A Quick Overview – Wine Analysis Procedures with the SC-300: Easy SO2 Test Attach SO2 electrode, press the power button, change to SO2 mode and press enter. Draw up 5 mL of titrant into the syringe and place 25 mL of wine in beaker. Add ~2 mL of the acidifier and ~2 mL of the reactant to wine. Place and hold the SO2 electrode in the wine sample and swirl beaker. Add titrant from syringe dropwise until 15 second long endpoint signal reached. Multiply the titration volume by 20, the SO2 conversion factor, results in ppm Free SO2. Simple pH Test Attach the pH electrode, set aside storage solution, rinse with DI water and blot gently with a paper towel. Press the power button then press the ‘Mode’ button and switch the SC-200 into ‘Cal’ mode. Calibrate using the pH 4 and pH 7 reference standards provided. Put the SC-200 in pH mode. Take 5 mL sample of wine, place in a beaker. Take a pH reading. Accurate TA Test For TA test, withdraw 5 mL of the TA Titrant with the syringe. Take 5 mL wine sample and add ~15 mL of deionized water. Put SC-200 into TA mode, place clean pH electrode gently in solution. Add TA Titrant from the syringe dropwise until the endpoint is reached indicated with the visual and audible signals. Record the volume (in mL) of titrant used. Multiply the titrantion volume by 2, the TA conversion factor, results in g/L Tartaric Acid. Vinmetrica Troubleshooting Guide

Used to determine the level of SO2 in your wine. Contains 10 tests in the form of glass titrets. They can be used by themselves or you can purchase W510B which is a titret holder. Please keep in mind that due to some chemical interference, this kit is only accurate to within +/- 30ppm when used to test red wines. Please note: the box states that this test kit is to be used with white wines only. However, we have found the kit can still be used for red wines as well. Titration tests are based on chemical reactions that cause a color change in the sample. This color change, which is much more obvious in white wine samples, will be harder to detect when used with red wine samples.

The SC-100A puts you in control of your wine sulfite analysis. It’s highly accurate and sensitive titration system conveniently alerts you visually and audibly when the endpoint is detected by its electrode. Because it doesn’t rely on a color change, the SC-100A eliminates the guesswork in Ripper sulfite tests, especially in red wines! The SC-100A analyzer gives you confidence to run your sulfite assays accurately and quickly. Kit includes everything to perform approx. 50 tests: electrode, reagents, pipettes, syringe and beaker. How It Works: The SC-100A improves on the tried and true Ripper Method by eliminating the guesswork in colorimetric analysis and replacing it with digital detection indicators. It uses an amperometric electrode and replaces the iodine reagent with a more stable reagent. Its ease of use and accurate amperometric titration method vastly improves on the original Ripper Method. The SO2 Titrant reacts with the sulfite in the wine. When all the free SO2 is titrated, the endpoint is signalled by visual and audible indicators. The test endpoint is much more sensitive than the starch endpoint commonly employed for sulfite titrations. It’s sharp and clear, even when titrating red wines and musts. Once the syringe titration is complete, determine the titration volume (which is the difference of titrant you started with and its final reading on the syringe) and multiply it by 20 (the conversion factor). The conversion factor takes into account the known concentration of the titrant and some simple unit conversions to determine the ppm Free SO2 in your wine sample. So for example if you used 1.2 mL of SO2 Titrant during the titration, your equation would look like this: 1.2 mL X 20 = 24 ppm Free SO2 Simple To Use Attach SO2 electrode, press the power button, change to ‘SO2′ mode and press enter. Draw up 5 mL of titrant into the syringe. Then place 25 mL of wine in beaker. Add ~2 mL of the acidifier and ~2 mL of the reactant to wine. Place and hold the SO2 electrode into the wine sample and swirl beaker. Add titrant dropwise, pause when device beeps, until 15 seconds of beeps reached. Multiply the titration volume by 20, the SO2 conversion factor, results in ppm Free SO2. Complete Kit Includes Everything You Need for Your First 50 Tests!

Finally - Accurate & Affordable Free SO2 Testing! In winemaking, Sulfur Dioxide (SO2) is one of the most important and effective tools in the winemaker's arsenal for protecting against the effects of oxidative or microbial spoilage. Unfortunately, over time any SO2 added to a wine will be consumed due to its interaction with the very things that it is protecting the wine from. The ability to accurately monitor the amount of SO2 remaining available in a wine to protect it - termed Free SO2 - is hugely important when it comes to ensuring that the wine makes it through the aging process safely. For years MoreWine! has offered a variety of methods for testing the level of Free SO2 in a wine. Until now, winemakers had to make a choice between inexpensive test kits which lacked accuracy and kits which are highly accurate but cost hundreds of dollars. Now MoreWine! has developed an inexpensive AND accurate test kit which we feel has a place in every home winery. Based on the exact same science as our original Aeration-Oxidation test kit, our new Economy Aeration-Oxidation kit offers a high degree of accuracy for a fraction of the price. Aeration-Oxidation is the exact same testing method used in thousands of commercial wineries and wine analysis laboratories around the world. It is time-tested and proven accurate and is simple to perform. Our kit includes:   All the glassware and tubing needed to set up a 2-chamber test apparatus Pipettes to accurately measure your wine sample and chemicals An aspiration pump to drive the chemical reaction in the test method Enough chemical reagents to run 2-3 tests Clear and comprehensive instructions for setting up and running the system PLEASE NOTE: This kit ships with a small bottle of 25% phosphoric acid which is required for the test. At this strength phosphoric acid is considered a hazardous material and we are not certified to ship larger quantities. We recommend that you investigate the possibility of sourcing it locally, through a laboratory supply company. If this is not possible, you can purchase it through us; see part #s MT108DS & MT108BDS. The high cost of these bottles reflects the $20 surcharge which FedEx adds to handle a hazardous shipment. These bottles ship directly from our supplier's warehouse and will take a couple of extra days to arrive. Click here to download a copy of our instruction manual for this kit.
