FAQs

What is pH 4.01 buffer solution used for?

pH 4.01 buffer solution is used to calibrate and verify the accuracy of pH meters and electrodes. It provides a stable, known reference point in the acidic range, ensuring reliable pH measurements in laboratory and field environments where precise calibration is critical.

What does NIST traceable mean for this buffer solution?

NIST traceable means the pH value of this buffer solution is verified against National Institute of Standards and Technology reference materials. This traceability ensures accuracy, consistency, and confidence in calibration results, supporting use in regulated laboratories, quality control processes, and professional testing environments.

Why is the buffer solution color-coded red?

The red color coding allows for quick visual identification of the pH 4.01 buffer, reducing the risk of using the wrong calibration standard. This is especially helpful in busy laboratories or field settings where multiple buffer solutions are used regularly.

How accurate is this pH 4.01 buffer solution?

This buffer solution has a pH value of 4.01 ± 0.02 at 25 °C, providing high accuracy for calibration purposes. This level of precision supports consistent pH meter performance and helps ensure reliable measurement results across repeated calibration cycles.

How should pH buffer solution be stored and handled?

The buffer solution should be stored tightly sealed at room temperature and protected from contamination. Always pour out a small amount for calibration rather than inserting electrodes directly into the bottle. Proper handling helps maintain accuracy and extends the usable life of the solution.
