FAQs:  
Q: When should I calibrate my pH meter, and why do I need to do it? 
A: The performance of a pH electrode or pH meter will change with time due to aging because as the electrode is used its coating degrades, to ensure it is working correctly, regular calibration is a must. If you are using your pH meter daily, you should calibrate it at least once a week. 

Q: How should I use Essentials LAB Buffer 4 to calibrate my pH meter? 
A: Ensure that your pH meter and the Buffer 4 solution are at similar temperatures, by keeping them in the same place for a while. Shake the bottle before use. Always pour a small amount into another container to test pH, and do not place your pH probe directly into the bottle. This will avoid contamination of the Buffer 4 in the bottle and will maintain its accuracy. After use, discard the solution used for calibration, and never put it back into the bottle. Follow the calibration instructions provided with your pH Meter. For more accurate, 2-point calibration, also use Essentials LAB Buffer 7. 

Q: How should I store Essentials LAB Buffer 4? 
A: Always keep the bottle upright with the cap screwed tight to avoid evaporation or spillage. Store your Buffer 4 at temperatures between 5°C and 25°C, and out of direct sunlight.
