The Specpure® grade guarantees purity and accuracy, while NIST traceability provides an added layer of certification for research and quality control. The solution is colorless, eliminating potential interference in optical measurements. Its stable formulation minimizes drift over time, making it ideal for frequent calibration tasks. The buffer is compatible with most standard laboratory equipment and adheres to international quality standards. Whether used in routine lab maintenance or critical research, this buffer solution delivers the precision needed for accurate pH measurements.
FAQs
1. What is the shelf life of this pH 7.00 buffer solution?
The shelf life is typically 24 months from the date of manufacture when stored unopened at room temperature. Always check the label for the exact expiry date.
2. Can this buffer be used with all types of pH electrodes?
Yes, this solution is compatible with most glass and combination pH electrodes. However, always verify compatibility with the electrode manufacturer’s recommendations.
3. Is this buffer solution autoclavable?
No, this buffer is not recommended for autoclaving as it may alter the pH value. Use sterile filtration if sterilization is required.
4. How should this buffer be stored to maintain accuracy?
Store the buffer in a tightly sealed container at room temperature (15-25°C). Avoid exposure to direct sunlight or extreme temperatures.
5. What alternatives are available if this pH value is not suitable?
For different calibration needs, consider pH 4.00 or pH 10.00 buffer solutions, which are also available in NIST-traceable grades.
