Buffer solutions PH 4, PH 7 and PH 9 are intended for calibration and maintenance of pH sensors (electrodes).

Color differences of calibration solutions:

  • Calibration (buffer) solution pH 4: pale red (pink) solution;
  • Calibration (buffer) solution pH 7: pale green solution;
  • Calibration (buffer) solution pH 9: pale blue solution;

It is necessary to store calibration solutions in a dark place, at a temperature not exceeding 25 ° С, away from direct sunlight to prevent photochemical reactions. In addition, buffer calibration solutions must be protected from the ingress of carbon dioxide from the air and stored in a tightly closed, sealed container. Each plastic bottle is labeled with the expiration date for that calibration solution.
