Product Overview
This pH 11.00 buffer solution is a high-precision calibration standard designed for laboratory applications requiring exact pH measurement. Formulated with Specpure® grade reagents, it ensures ±0.01 accuracy at 25°C, making it suitable for critical analytical procedures. The colorless solution eliminates optical interference, while NIST traceability guarantees compliance with international standards. Packaged in a 550 mL bottle, it provides sufficient volume for repeated calibrations without contamination risks. The solution maintains stability under standard lab conditions, though proper storage is recommended to preserve its certified accuracy. Its non-reactive composition prevents electrode damage, extending the lifespan of pH meters. The tightly sealed packaging prevents CO₂ absorption, which could alter pH values over time. This buffer solution represents an essential tool for maintaining instrument accuracy in research and quality control environments.
FAQs
1. What is the shelf life of this pH 11.00 buffer solution when unopened?
The unopened solution typically maintains its certified pH accuracy for 24 months from the date of manufacture when stored at room temperature in its original sealed container.
2. Can this buffer be used with combination pH electrodes?
Yes, it is fully compatible with all standard combination pH electrodes, including glass-body and epoxy-body types, as it contains no components that would damage electrode membranes.
3. How does the NIST traceability affect calibration accuracy?
NIST traceability means the solution’s pH value has been verified against primary standards from the National Institute of Standards and Technology, ensuring your calibrations meet international metrological requirements.
4. What precautions should be taken when handling this high-pH buffer?
While not corrosive, the alkaline nature requires standard lab precautions: wear nitrile gloves, avoid skin contact, and rinse electrodes with deionized water after use to prevent carryover contamination.
5. Is this buffer solution autoclavable for sterile applications?
This particular formulation is not recommended for autoclaving as the high pH and heat combination may alter the certified pH value and potentially degrade the container.
