Product Overview
This pH 11.00 buffer solution is a high-precision, NIST-traceable reference standard designed for accurate pH meter calibration and laboratory testing. The Specpure® grade ensures minimal impurities, providing reliable and consistent results in critical applications. With a tightly controlled pH of 11.00 (±0.01 at 25°C), this colorless solution eliminates interference from dyes, making it ideal for sensitive measurements. The formulation adheres to strict quality standards, ensuring long-term stability and repeatability. Available in convenient pack sizes (500ml, 1L, 4L), it caters to both small-scale experiments and bulk laboratory requirements. The solution is compatible with most pH electrodes and calibration protocols, offering versatility across different instrumentation setups. Its NIST traceability guarantees compliance with international metrology standards, making it a trusted choice for research, quality control, and educational laboratories. The absence of colorants prevents potential contamination or spectral interference in analytical procedures. This buffer solution maintains its specified pH value over extended periods when stored properly, reducing the need for frequent recalibration and ensuring cost-effective laboratory operations.
FAQs
1. What is the shelf life of this pH 11.00 buffer solution?
The shelf life is typically 24 months from the date of manufacture when stored unopened at room temperature, away from direct sunlight and moisture.
2. Can this buffer solution be used with all types of pH electrodes?
Yes, it is compatible with most standard pH electrodes, including glass and combination electrodes, as it contains no additives that could damage electrode membranes.
3. How should I store this buffer solution after opening?
After opening, tightly recap the bottle and store it in a cool, dry place. For best results, use within 6 months of opening to maintain accuracy.
4. Is this buffer solution suitable for high-temperature applications?
The solution is optimized for use at 25°C, and its pH accuracy may vary at elevated temperatures. For temperature-sensitive applications, recalibrate your meter at the working temperature.
5. What makes this buffer solution NIST traceable?
NIST traceability means the pH value has been verified against standards provided by the National Institute of Standards and Technology, ensuring measurement accuracy and reliability.
