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 indicated with 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.
