Carbon Dioxide Chemical Test Kit Replacement Reagents (110 tests) - HI3818-100

$49.81

The HI3818-100 are reagents for the determination of carbon dioxide by titration with the carbon dioxide chemical test kit. There are enough reagents for approximately 110 tests to be used with Hanna’s test kit. These high quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each packet for traceability.

  • Pre-made reagents for ease of use
  • Prepared with high-purity chemicals
  • Marked with expiration date and lot number for traceability

The HI3818-100 are high-quality reagents that are pre-measured, allowing users to achieve fast and accurate carbon dioxide measurements with the chemical test kit. These reagents follow the phenolphthalein method to determine carbon dioxide concentration.

For carbon dioxide determination, dilute sodium hydroxide is used as the titrant. With addition of phenolphthalein indicator, the solution turns pink to visually indicate it is near the pH endpoint of pH 8.3. The number of milliliters of titrant used to reach the endpoint will determine the carbon dioxide concentration as mg/L CO2. These reagents are designed to be used with samples that have an expected carbon dioxide range of 0.0 to 10.0 mg/L, 0.0 to 50.0 mg/L, and 0 to 100 mg/L CO2.
