FAQs
1. What is the shelf life of this pH 12.00 buffer solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at room temperature. After opening, use within 6 months for optimal accuracy.
2. Can this buffer be used with glass electrodes?
Yes, it is fully compatible with standard glass pH electrodes. The Specpure® grade ensures no leachable ions that could damage or contaminate electrode surfaces.
3. Is this buffer solution autoclavable?
Autoclaving is not recommended as it may alter the pH value. Use sterile filtration (0.22 µm) if sterility is required.
4. How does NIST traceability benefit my calibration process?
NIST traceability provides documented proof that the buffer’s pH value is linked to primary standards, ensuring your measurements meet regulatory and ISO compliance requirements.
5. What alternatives exist for pH 12.00 calibration if this product is unavailable?
For temporary use, pH 11.00 or pH 13.00 buffers can serve as substitutes, but recalibration with a pH 12.00 standard is recommended once available to maintain precision.
