Professional Standard pH Buffer Solution for Accurate Calibration
Accurate pH measurement requires a reliable calibration standard. Xintester standard pH buffer solution is designed for calibrating pH meters and electrodes, helping users achieve stable and repeatable testing results. Manufactured with high-purity chemical materials and strict quality control, our pH calibration buffer provides a dependable reference solution for laboratories, water quality testing, agriculture, food testing, education, and industrial applications. Regular calibration helps compensate for electrode drift, maintain measurement accuracy, and extend the service life of pH testing equipment.
1Multiple pH Calibration Values
Different applications require different calibration points. Xintester provides commonly used pH buffer values including 1.68, 4.00, 6.86, 7.00, 9.18, 10.00, and 11.00. These options cover acidic, neutral, and alkaline testing ranges, allowing users to perform one-point, two-point, or multi-point calibration for different pH meters and testing requirements.
2Flexible Bottle Sizes
To meet different usage needs, Xintester offers multiple capacity options including 50mL, 100mL, 250mL, and 500mL. Small users can select compact bottles for occasional calibration, while laboratories, schools, and industrial customers can choose larger volumes for frequent testing and long-term operation.
3Durable HDPE Packaging
Each pH calibration solution is packaged in a high-quality HDPE bottle with excellent chemical resistance and storage stability. The secure cap design helps prevent leakage during transportation, while the convenient bottle structure makes daily use easier and reduces the risk of contamination.

FAQs
Q: How often should I calibrate my pH meter?
A: You should calibrate your instrument before every major testing session. Specifically, daily calibrations ensure maximum accuracy for continuous laboratory testing. Therefore, keeping fresh pH buffer solution on hand is highly recommended.
Q: Can I pour the used buffer solution back into the original bottle?
A: No, absolutely not. You must always discard the used liquid after finishing your calibration. Pouring it back will contaminate your entire fresh supply instantly. Consequently, you will ruin your future test results.
Q: Does temperature affect the pH reading of the buffer?
A: Yes, temperature changes the pH value slightly. Our stated values are perfectly accurate at 25°C (77°F). Therefore, you should always use a meter equipped with Automatic Temperature Compensation (ATC) for the best results.
Q: How should I store these HDPE bottles properly?
A: You must keep the caps tightly sealed at all times. Specifically, you should store the bottles in a cool, dry, and dark laboratory cabinet. Direct sunlight and extreme heat degrade the chemicals rapidly.
