Product Overview
This pH 1.679 ± 0.010 buffer solution is a high-precision secondary standard designed for reliable pH meter calibration and laboratory accuracy verification. Formulated with strict quality control, it ensures consistent performance across various lab environments. The solution maintains its stability over time, reducing the need for frequent recalibration and minimizing measurement errors. Its secondary standard grade makes it suitable for routine lab use where traceability to primary standards is not required. The liquid form allows for easy handling and dispensing, while the 500 ml pack size provides sufficient volume for regular calibration needs without excessive waste. The narrow pH tolerance of ±0.010 guarantees precise calibration, which is critical for experiments requiring exact pH measurements. This buffer solution is particularly valuable in environments where maintaining consistent pH readings is essential for experimental reproducibility and data integrity.
FAQs
1. How stable is this pH 1.679 buffer solution over time?
This buffer solution is formulated for long-term stability, maintaining its pH value within the specified ±0.010 range when stored properly in its original container.
2. Can this buffer be used with all types of pH electrodes?
Yes, this solution is compatible with most standard pH electrodes, including glass and combination electrodes commonly used in laboratory settings.
3. What’s the shelf life of this buffer solution?
The solution typically maintains its specified pH range for 12-18 months from the date of manufacture when stored at room temperature in a tightly sealed container.
4. How does this compare to primary standard buffer solutions?
As a secondary standard, this solution offers excellent precision for routine calibration but isn’t traceable to NIST standards like primary buffers. It’s ideal for daily lab use where primary standard traceability isn’t required.
5. What’s the recommended storage condition for this buffer?
Store at room temperature (15-25°C) in the original container with the cap tightly closed to prevent contamination and evaporation.
