Product Overview
This pH 13.00 buffer solution delivers unmatched precision with a tolerance of ±0.01 at 25°C, ensuring reliable calibration for critical laboratory applications. Formulated as a colorless liquid, it adheres to the stringent Specpure® grade standards, guaranteeing consistency and purity for sensitive measurements. NIST traceability provides an additional layer of certification, making it a trusted reference for high-accuracy pH testing. The solution is stable under standard lab conditions, minimizing variability in results. Its high alkalinity (pH 13.00) makes it particularly suitable for calibrating electrodes in extreme pH ranges, where precision is non-negotiable. The 550 mL pack size offers an optimal balance between usability and shelf life, reducing the need for frequent replacements while maintaining freshness. Free from colorants, it eliminates potential interference in spectroscopic or visual analyses, ensuring data integrity. Whether used in research, quality control, or educational settings, this buffer solution meets the demands of modern analytical workflows where reproducibility and traceability are paramount.
FAQs
1. What is the shelf life of this pH 13.00 buffer solution when stored properly?
The solution remains stable for up to 24 months from the date of manufacture when stored in its original sealed container at room temperature, away from direct sunlight and moisture. Always check the expiration date on the label before use.
2. Can this buffer be used with glass electrodes, or is it compatible only with specific pH meters?
This NIST-traceable buffer is universally compatible with all standard pH electrodes, including glass and combination electrodes. Its high purity and lack of colorants make it safe for use with sensitive probes without risking contamination or signal interference.
3. How does the Specpure® grade differ from standard analytical-grade buffers?
Specpure® grade buffers undergo additional purification steps to remove trace impurities, ensuring tighter pH tolerance (±0.01) and higher lot-to-lot consistency. This grade is designed for applications where even minor deviations can impact results, such as pharmaceutical testing or environmental analysis.
4. Is recalibration required if the solution is exposed to temperature fluctuations during storage?
While the buffer is formulated to resist minor temperature variations, prolonged exposure to extremes (below 10°C or above 30°C) may alter its pH. If stored outside the recommended range, verify the pH with a secondary standard before use or recalibrate your meter.
5. Are there any safety precautions needed when handling this high-pH buffer solution?
As a strongly alkaline solution (pH 13.00), it can cause skin and eye irritation. Wear nitrile gloves, safety goggles, and a lab coat when handling. In case of contact, rinse immediately with plenty of water and consult the SDS for further guidance. Avoid inhaling vapors in poorly ventilated areas.
