FAQs

What is buffer solution pH 4 used for?

Buffer solution pH 4 is commonly used for pH meter calibration and maintaining acidic pH conditions during analytical procedures. It is widely applied in laboratories, environmental testing, food and beverage analysis, pharmaceutical workflows, and industrial quality control where accurate pH measurement is required.

Why is pH 4 buffer important for calibration?

pH 4 buffer is a key reference point for calibrating pH meters in the acidic range. Using a NIST-traceable pH 4 standard helps ensure accurate readings, reliable instrument performance, and consistency across analytical measurements and quality control processes.

What does NIST traceable mean for this buffer solution?

NIST traceable means the pH value is verified against standards from the National Institute of Standards and Technology. This provides confidence in accuracy, supports regulatory compliance, and makes the buffer suitable for calibration, validation, and quality assurance applications.

What is the purpose of the red color indicator?

The red color indicator allows quick visual identification of the pH 4 buffer, reducing the risk of mix-ups with other buffer solutions. This is especially helpful in busy laboratories where multiple pH standards are used for calibration and routine testing.

How should buffer solution pH 4 be stored and handled?

Store the buffer solution tightly sealed at 15–25 °C and protect it from contamination. Use clean containers and electrodes when dispensing. Always follow standard laboratory practices and refer to the Safety Data Sheet for proper handling, storage, and disposal instructions.
