Calibration of a redox probe: Use of water as a neutral solution

Contact:
Good morning. I would like to calibrate a redox probe and still have the buffer solution from last year. I would like to buy new ones, including the neutral solution. I found everything in your range, except for the neutral solution.

Advisor:
Good morning. For the neutral solution used for cleaning, simply use water.
