Frequently Asked Questions
1. How often should I calibrate my pH meter with these buffers?
For professional laboratory work, it is recommended to calibrate your meter daily or before each measurement series to account for electrode drift and environmental changes.
2. Does temperature affect the pH of the buffer solution?
Yes, the pH of all buffers changes with temperature; professional solutions like those from Reagecon specify the pH value at 25°C and often provide a temperature correction table on the label.
3. Can I reuse buffer solutions once they have been poured into a beaker?
No, you should never return used buffer to the original bottle or reuse it for subsequent calibrations, as atmospheric CO2 and sample carryover will contaminate the solution and lead to errors.
4. What is the shelf life of these pH standards?
While sealed bottles have a longer shelf life, once opened, alkaline buffers (like pH 10.00) are more susceptible to CO2 contamination and typically have a shorter usable life than acidic buffers (like pH 4.00).
