A pH standard is a liquid widely used in chemical and biological laboratories with a known pH value that is used to calibrate and adjust pH measuring instruments to ensure the accuracy of measurement results. pH standards are primarily used to calibrate pH meters and pH electrodes, ensuring that these instruments provide accurate and reliable pH measurements. During experiments and analyses, pH standards can be used as control samples to help verify and confirm the accuracy of pH values measured in experiments.
pH 4.01, 7.00, and 10.01 standards: This is a common pH standard series used to calibrate most pH instruments. Each standard has an accurate pH of 4.01, 7.00, and 10.01, respectively.
When selecting pH standards, choose products with high accuracy from the manufacturer to ensure reliable measurement results.
pH standards should be stored in a dry, cool environment, avoiding exposure to air and light, to maintain their stability.
pH standards are an indispensable calibration and validation tool in the laboratory to ensure the accuracy and reproducibility of pH measurements. When using it, it is necessary to follow the relevant laboratory protocols and regularly check and update the pH standard.
