FAQs

What is pH 12.45 Certified Reference Material (CRM) buffer solution used for?

pH 12.45 CRM buffer solution is used for calibrating pH meters and probes that operate in high-alkaline ranges. It provides a certified reference point for laboratories and quality control environments that require accurate, traceable calibration for caustic or alkaline measurement applications.

What does Certified Reference Material (CRM) mean?

Certified Reference Material means the buffer is supplied with a Certificate of Analysis verifying its exact pH value and uncertainty. This certification ensures traceability, accuracy, and reliability, making the solution suitable for regulated environments, quality audits, and calibration workflows requiring documented reference standards.

How accurate is the pH 12.45 buffer solution?

This buffer solution has a certified pH value of 12.45 ± 0.05 at 25 °C. This defined tolerance supports precise calibration of pH instruments, helping ensure consistent measurement performance when working with highly alkaline solutions or processes.

Why is this buffer manufactured to IUPAC standards?

Manufacturing to IUPAC standards ensures the buffer composition and pH value align with internationally recognized reference methodologies. This provides confidence that calibration results are consistent, comparable, and suitable for professional laboratory, industrial, and research applications requiring standardized measurement practices.

How should this high-pH buffer solution be handled and stored?

The buffer solution should be stored tightly sealed at room temperature and protected from contamination. For calibration, pour a small amount into a clean container rather than immersing probes directly into the bottle. Proper handling helps maintain certification integrity and measurement accuracy over time.
