The PH 4.00 buffer solution is prepared with the correct Ph sensor immersion solution. 

The solution is dissolved in 250ML pure water, and 56g of analytical pure KCl is added. In order to make the use of the PH composite electrode more convenient, some imported pH composite electrodes and some domestic electrodes are equipped with a sealed plastic vial at the head of the Ph composite electrode, which is filled with electrode soaking solution, and the electrode head is immersed in it for a long time, when used, it can be pulled out and washed, which is very convenient. This storage method is not only convenient, but also to extend the life of the electrode is very favorable, pH electrode but plastic bottles in the immersion solution do not be contaminated, pay attention to replace.
