Does the pH meter standard buffer solution need to be prepared immediately?
A pH meter is a common instrument used in laboratories to measure the pH of a solution. To ensure the accuracy of the measurement results, the pH meter needs to be periodically calibrated with standard buffer solutions.
The standard buffer solution can be prepared in advance, and the prepared solution can generally be stored for 2 to 3 months, but some solutions can only be stored for half a month to a month due to the easy deterioration. continue to use. In order to obtain the most accurate calibration effect, it is generally recommended that qualified laboratories use standard buffer solutions that are ready to use.
