Product Overview
This high-precision pH 13.00 buffer solution offers exceptional accuracy with a tolerance of ±0.01 at 25°C, making it ideal for demanding laboratory applications. Formulated as a colorless liquid, it adheres to the rigorous Specpure® quality standards, ensuring minimal impurities and consistent performance. The solution is NIST traceable, providing documented calibration references that meet international metrology standards. Its stable formulation resists contamination and maintains pH integrity over extended storage periods when properly sealed. The buffer’s high alkalinity range makes it particularly valuable for calibrating electrodes in extreme pH environments. Available in laboratory-friendly pack sizes, this solution eliminates the need for in-house preparation while delivering professional-grade results. The absence of coloring agents prevents potential interference with optical measurements or spectroscopic analysis. Each batch undergoes stringent quality control to verify pH accuracy before distribution, guaranteeing reliable performance in critical applications.
FAQs
1.What is the shelf life of this pH 13.00 buffer solution when unopened?
The solution maintains its specified pH accuracy for 24 months from the date of manufacture when stored in its original sealed container at room temperature. 2.
2.Can this buffer be used with glass electrodes and combination pH electrodes?
Yes, it is fully compatible with all standard pH electrodes including glass and combination types, though we recommend rinsing with distilled water between measurements. 3.
3.How should I dispose of expired or unused buffer solution?
Neutralize with a weak acid before disposal according to your institution’s chemical waste protocols, as the high pH requires proper handling. 4.
4.What’s the difference between this and standard pH 12 buffer solutions?
This solution offers tighter tolerance (±0.01 vs typical ±0.02) and NIST traceability, making it superior for calibration where extreme precision is required. 5.
5.Does the plastic packaging affect the pH stability over time?
The HDPE bottles are chemically inert and specifically selected to prevent leaching or pH drift during the product’s shelf life.
