The HI84500-62 are packets of stabilizer reagent required for determination of sulfur dioxide in wine using the HI84500 Sulfur Dioxide Mini Titrator for Wine Analysis. The HI84500 mini titrator uses two different titrant solutions that contain different concentrations of potassium iodate to measure a wide range of sulfur dioxide concentration in wine. Both low and high range measurements require the addition of HI84500-62 stabilizer powder to convert iodate into iodine, which in turn reacts with sulfur dioxide. The HI84500-62 powder is packaged into single use packets that are emptied into the sample prior to performing the titration. Pre-measured packets Clearly marked expiration date and lot number The HI84500-62 stabilizer powder packets are necessary to convert the iodate titrant into iodine. The iodine then reacts with sulfur dioxide and 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 decision by Hanna to use the HI84500-62 stabilizer powder packets and iodate titrant in place of a iodine titrant is due to shelf stability. Iodate offers much greater shelf stability than iodine. By using stabilizer packets the titrant solutions remain stable for longer periods of time.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 of SO2 High Range - 30 to 400 ppm of 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

.30M KCl (potassium chloride) solution for refillable pH/ORP electrodes. Fresh electrolyte solution ensures accurate calibration and measurement with your pH meter. For best results, electrolyte should be replenished or completely replaced every 3-6 months. To Use: Wearing Gloves, Drain existing electrolyte solution from the electrode by shaking upside down over the sink. You may need to use the tip of a small pipette or a syringe to break the surface tension of the liquid. Using the same pipette or syringe, replace the solution you just drained with a fresh lot from the bottle. Store capped and refrigerated and out of the reach of children.
