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.\u003c\/div\u003e\r\n\u003cul\u003e\r\n\t\u003cli\u003e\r\n\t\t\u003cdiv\u003e\r\n\t\t\tPre-measured solution\u003c\/div\u003e\r\n\t\u003c\/li\u003e\r\n\t\u003cli\u003e\r\n\t\t\u003cdiv\u003e\r\n\t\t\tClearly marked expiration date and lot number\u003c\/div\u003e\r\n\t\u003c\/li\u003e\r\n\t\u003cli\u003e\r\n\t\t\u003cdiv\u003e\r\n\t\t\tAir tight bottle with tamper-proof seal to ensure quality\u003c\/div\u003e\r\n\t\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003cdiv\u003e\r\n\t\u003cdiv\u003e\r\n\t\tThe 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.\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\t \u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tThe HI84500 determines the free and total sulfur dioxide concentration in wine using the Ripper method.
