The colorless composition eliminates optical interference, making it suitable for spectrophotometric applications where clarity is critical. The solution is pre-mixed to exacting specifications, reducing preparation time while delivering consistent performance across repeated calibrations. Its sealed packaging prevents contamination and extends shelf life, ensuring long-term reliability. Compatible with most pH electrodes, this buffer solution provides a dependable baseline for routine lab maintenance, quality control, and research applications requiring stringent pH accuracy. The absence of added dyes or preservatives further enhances its suitability for sensitive analytical procedures.
FAQs
1. What is the shelf life of this pH 9.00 buffer solution when unopened?
The unopened buffer solution has a shelf life of 24 months from the date of manufacture when stored at room temperature in its original packaging.
2. Can this buffer be used with glass and epoxy-body pH electrodes?
Yes, the solution is compatible with both glass and epoxy-body pH electrodes, as it does not contain components that degrade electrode materials.
3. Is this buffer solution autoclavable for sterile applications?
This buffer is not recommended for autoclaving, as heat exposure may alter its pH stability and chemical composition.
4. How does NIST traceability benefit calibration accuracy?
NIST traceability ensures the buffer’s pH value is verified against primary standards, providing a documented chain of comparison that enhances measurement reliability and compliance with ISO guidelines.
5. What alternatives exist for pH 9.00 buffers with similar specifications?
Alternatives include ACS-grade pH 9.00 buffers or buffers certified by other metrology institutes, though these may vary in traceability documentation and ionic purity.
