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.

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.

Happy with equipment, pore instruction
I am very happy with the equipment. The instructions are bad and I had to go to YouTube to learn how to use it right.

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.

Easy and accurate.
Perfect meter to help keep the SO2 in check. Easy to use and great improvement in our finished wines.

Worked well but should have came with ph test strips or notified they are nessasry to do the test.
Would've got 5 stars.

Works as indicated
Maybe a bit fiddly if you have not performed analytical methods via titration before but I found the method reasonable and able to direct me towards appropriate addition amounts for my wines in process (barrel aging) and bottling. I think it has the appropriate fidelity for the hobby wine maker vs. just periodically adding bisulfate on a guess. I recommend this product. The only reason I gave 4 stars vs. 5 is there is no detailed information regarding the titrant and reagents so you are beholding to Vinmetrica to buy more from them.

Appreciated free SO2 test kit
I give this a 4 Star only because I have just used it a few times. But I appreciate this item because I no longer have to guess at the shade of pink/purple with the accuvin free SO2 tests. Also this will be much more cost effective especially now that I perform more free SO2 tests with the variety of wines I make. This takes a tad bit more time to test free SO2 but I feel much more confident with my readings now.

Easy to use. I like the audible tone that tells you when you are close to your endpoint. Test takes literally 2 minutes. Accuracy seems pretty good.
