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

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.

• 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.
