FAQs

1. What is the shelf life of this pH 12.45 buffer solution?

The solution remains stable for 24 months from the date of manufacture when stored unopened at room temperature. Once opened, use within 6 months for optimal accuracy.

2. Can this buffer be used with glass and epoxy pH electrodes?

Yes, it is fully compatible with both glass and epoxy-body pH electrodes, as well as most combination electrodes used in standard laboratory setups.

3. How does NIST traceability benefit my calibration process?

NIST traceability ensures the buffer’s pH value is verified against national standards, providing documented accuracy that supports compliance with ISO, GLP, and other quality protocols.

4. Is this buffer solution sterile or require autoclaving?

The solution is not sterile but is formulated with preservatives to inhibit microbial growth. Autoclaving is not recommended as it may alter the pH value.

5. What alternatives exist for pH 12.45 calibration if this is unavailable?

For temporary use, pH 12.00 or pH 13.00 buffers can serve as alternatives, though they will require recalibration of your meter to account for the pH difference.
