Hanna Alkaline Solution for Titrator - 120mL (Hanna# HI84500-61)

The HI84500-61 is a 120 mL bottle of alkaline reagent required for determination of total sulfur dioxide in wine using the HI84500 Sulfur Dioxide Mini Titrator for Wine Analysis. This alkaline reagent is used to raise the pH value of the sample prior to performing a total sulfur dioxide titration. With 5 mL of reagent required per total SO2 test, there is enough alkaline reagent for approximate 24 tests.
  • Pre-measured solution
  • Clearly marked expiration date and lot number
  • Air tight bottle with tamper-proof seal to ensure quality
The HI84500-61 alkaline reagent is necessary for the analysis of total sulfur dioxide. The alkaline reagent raises the pH and liberates bound sulfur dioxide. This pH adjustment ensures that all of the free and bound sulfur dioxide is accounted for to give an accurate measurement of total sulfur dioxide. The HI3148B ORP electrode is used to detect the endpoint for both the low (1.0 to 40.0 ppm of SO2) and high (30 to 400 ppm of SO2) ranges. The HI84500 can be used with all wines, including red, which are difficult to test using traditional methods due to the difficulty to observe a distinctive color change when the endpoint is reached.
 
The HI84500 determines the free and total sulfur dioxide concentration in wine using the Ripper method. Excess iodide is added to the wine sample and reacts with the iodate titrant to produce iodine:
 
IO3- + 5I- + 6H+ → 3I2 + 3H2O
 
The iodine produced reacts with sulfur dioxide in the wine according to the redox reaction below:
 
H2SO3 + I2 → H2SO4 + 2HI
 
Replacement reagents required to operate the HI84500 include:
 
  Low Range - 1.0 to 40.0 ppm SO2 High Range - 30 to 400 ppm SO2
Pump calibration standard HI84500-55 HI84500-55
Titrant solution HI84500-50 HI84500-51
Acid reagent HI84500-60 HI84500-60
Alkaline reagent (Total SO2) HI84500-61 HI84500-61
Stabilizer powder packets HI84500-62 HI84500-62
  • Requires only 5mL per test.
  • Pre-measured solution with clearly marked expiration date and lot numbers in a tamper proof bottle, can be utilized for all wines including red.
