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

  1. Attach SO2 electrode, press the power button, change to ‘SO2′ mode and press enter.
  2. Draw up 5 mL of titrant into the syringe. Then 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 into the wine sample and swirl beaker.
  5. Add titrant dropwise, pause when device beeps, until 15 seconds of beeps reached.
  6. 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!

  • SO2 reagents
  • Titration beaker
  • 5 mL syringe
  • SO2 electrode
  • 25 mL sampling pipette
  • 2 transfer pipettes

Custom Vinmetrics SC-100A SO2 Analyzer Kit Box
I absolutely love my new Vinmetrics SC-100A SO2 Analyzer Kit. I build a box to house my new kit. I was using the Hanna Instruments Mini Titrator for Measuring Titratable Acidity. It was putting me in the poor house with the maintenance of the parts to keep it operational. This kit is easy to use, accurate with fewer parts to maintain. I plan on adding a Lab Support Stand and Magnetic Stirrer. The box was easy to build and will protect the electrode and chemicals.

It is an important analyzer for perfecting my wines.
Works very well. Takes a little practice to zero in on the end point.

Works great
It is simple to use and very accurate. My only complaint is that is took a long time (a month) to arrive to my Canadian address because it was held in customs for an unknown reason.

Excellent performance and value
I recently used the Vinmetrica SC-100A kit and am very pleased with how the instrument performed. I used it to check the free SO2 level on three wines that are aging. I’m more confident now in knowing how much free SO2 I really have versus what I thought I had. I also like the fact that the kit comes with everything needed to perform the tests.

Fast and easy SO2 testing
This has taken the guess-work out of sulfite adjustments. It takes less than 5 minutes for entire procedure. No more premature oxidation/spoilage problems due to incorrect sulfite additions. A great tool to have.

If you are concerned about free SO2 in your wine, buy this item
The SC-100 is easy to use and gives reproducible results on free SO2 in wine. You need a good pH meter as well, but it allows accurate SO2 determination and is much cheaper and faster than sending wine samples out for analysis, which is the only other option.
