The Vinmetrica SC-300 Pro Kit

The Ultimate Winemaker’s Laboratory

One lean, mean wine analyzing machine.The SC-300 Pro Kit combines the SO2 detection of the SC-100 and the pH/TA analysis of the SC-200 into one power-packed instrument. Plus, with the added precision and convenience of the accessories provided in the SC-300 Pro Kit, you have a powerful compact Wine Laboratory at your fingertips! It’s built on the same hardware and software as our other two analyzers, so the accuracy and precision is superb. And it’s just as easy to use ? The audible buzzer and visual stop light will automatically let you know when your 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!

The SC-300 Pro Kit gives accurate SO2, pH and TA values. Kit includes everything to perform about 50 sulfite tests and 30 TA tests.The Vinmetrica SC-300 SO2 and pH/TA analyzer has been paired up with the following accessories:

  • Trying to figure out which size glass burette to purchase? Both sizes are able to measure accurately within 0.2 mL, however the 25mL option is easier when you are conducting multiple tests because you will not have to refill it as often as you would the 10mL option.

    Now you can measure SO2 and pH/TA quickly and easily so you can focus on what matters, making high quality wines!

    Already have an SC-100A, SC-200 or SC-300 but want the added convenience and precision of having your own Laboratory? Check out the Deluxe Lab Accessory Kit which will give you added convenience, making a large number of sulfite tests easier and further resolved.

    A Quick Overview – Wine Analysis Procedures with the SC-300:

    Easy SO2 Test

    1. Press the power button, change to SO2 mode and press enter.
    2. Attach SO2 electrode. Draw up 5 mL of titrant into the syringe and place 25 mL of wine in beaker.
    3. Add ~2 mL of the acidifier and ~2 mL of the reactant to wine.
    4. Place and hold the SO2 electrode in the wine sample and swirl beaker.
    5. Add titrant from syringe dropwise until 15 second long endpoint signal reached.
    6. Multiply the titration volume by 20, the SO2 conversion factor, results in ppm Free SO2.

    Simple pH Test

    1. Attach the pH electrode, set aside storage solution, rinse with DI water and blot gently with a paper towel.
    2. Press the power button then press the ‘Mode’ button and switch the SC-300 into ‘Cal’ mode.
    3. Calibrate using the pH 4 and pH 7 reference standards provided. Put the SC-300 in pH mode.
    4. Take a 5 mL sample of wine, place it in the beaker. Take a pH reading.

    Accurate TA Test

    1. For the TA test, withdraw 5 mL of the TA Titrant with the syringe.
    2. Take 5 mL wine sample and add ~15 mL of deionized water.
    3. Put SC-300 into TA mode, place clean pH electrode gently in solution.
    4. Add TA Titrant from the syringe dropwise until the endpoint is reached indicatedwith the visual and audible signals. Record the volume (in mL) of titrant used.
    5. Multiply the titration volume by 2, the TA conversion factor,results in g/L Tartaric Acid.

    How It Works

    The SO2 function 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 by20(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

    The SC-300 also includes a pH electrode and reagents for calibration and determination of pH and titratable acidity (TA) values in wines and other samples. The pH value is simply determined by placing the calibrated electrode into a sample and reading the value. TA is determined by titrating a 5 mL sample of wine to an endpoint pH of 8.2* with the TA titrant (0.13N NaOH) from the syringe in the kit. From the known concentration of the TA titrant and its volume required to reach the endpoint, the TA is simply calculated (results are in units of g/L tartaric acid).

  1. Dr. Tod Pelly

    I had a calibration issue so I called them on a Saturday, hoping to have someone call me back on the following Monday. The tech called me from his cell that day, he was with friends or family (couldn’t tell) and walked me through the recalibration. I can’t tell you how much that helped me and I’m now a loyal promoter of their company. If there were more stars than five, I’d give it.

  2. Fred Vernacchia

    This is a great product! I needed to get a full analysis of my wine prior to bottling so I ran tests with the SC300 3 days before a commercial lab. Two wines analyzed.
    Wine #1
    My results: pH 3.65, TA 0.59, Free SO2 30 ppm
    Commercial Lab 3.68, 0.544, 32 ppm

    Wine #2
    My Results pH 3.52, TA 0.70 Free SO2 24 ppm
    Commercial Lab 3.58, 0.672, 21 ppm

    Don’t know about you, but this is certainly close enough for me and this is food product we are measuring, NOT a pharmaceutical. One more thing, I am not a big believer in expiration dates on drugs or reagents. I think if stored well, they last way longer than professed. My tests were done with Vinmetrica reagents that are 7-8 months old. They say they are only good for 6 months. I disagree. Store them well in a cool environment and I think they last easily twice as long.
