buffer solutions as possible, i.e. to ensure that a pH 7 buffer solution in fact has
a pH value of exactly 7.
MJK delivers buffer solutions for both pH and redox calibration.
The pH value of the buffer solution is dependent of the temperature, and the
stated pH value is valid at 77° F / 25° C.
Buffer solution has a limited lifetime. Buffer solution for pH 4 and 7 has a life
time of app. one year, and buffer solution for pH 10 a somewhat shorter
lifetime.
Note! Buffer solution with pH 10 is very unstable and should therefore be
disposed of no later than 10-15 minutes after it has been poured from the
bottle.
Cleaning
Before starting buffer adjustment, wash the electrode in running drinking water
and wipe it with a cloth before immersing it in the buffer solution. Washing and
wiping must be repeated between each step of the buffer adjustment.
