Complete kit in plastic case for free and total SO2 determination (Ripper method)

Manual titration of sulphurous anhydride

This kit offers all the necessary instruments for testing in a perfectly organized case. It includes a 25ml automatic self-zeroing burette, a stand, a dosing cylinder, an Erlenmeyer flask, reagents, and a standard solution in flexible flask. The plastic case facilitates the transportation and oganization of the instruments and their protection when they are not in use.

  • Only one test to determine the two values (free and total SO2).
  • Mesurement of the sample and the reagents with a dosing cylinder. 
  • Accurate titration with an automatic self-zeroing burette. 
  • Stable solutions over several months.


The SO2 is completely released in acid medium and titrated with the standard iodide/iodate solution in the presence of a starch indicator. The starch indicator changes colors to give the result of the test. The free SO2 and the total SO2 are successively determined by the iodide/iodate solution stable over the time (KIKIO3), that produces the iodine specifically for the titration. All the volumes are measured with a dosing cylinder.
