4. How to Use pH 4-7-10 Buffer SolutionsTo ensure accurate calibration and safety, follow these steps:

• Preparation:
  • Use fresh pH buffer solutions and avoid reusing poured solutions to prevent errors.
  • Ensure the buffer solution and test sample are at a similar temperature (typically 25°C) for accurate results.
• pH Meter Calibration:
  • Rinse the pH electrode with distilled water before each measurement.
  • Immerse the electrode in the pH 7.00 solution first, followed by pH 4.00 and pH 10.00 (or as per your pH meter’s instructions).
  • Adjust the pH meter to match the standard values until the display is accurate.
• Storage:
  • Store solutions in a cool, dry place, away from direct sunlight and high temperatures.
