pH Calibration and Cleaning

Here we list our range of calibration buffer and cleaning solutions. All pH meters will lose calibration. It is important to calibrate meters before each use and even during usage if you are measuring a lot of samples. If you use your meters regularly they will hold calibration better however meters that are not used regularly may need to be calibrated a few times before usage.

Remember to store your electrodes in storage solution or pH 7 buffer solution to keep electrodes moist. After a lot of usage it is a good idea to use cleaning solutions to remove proteins from your electrodes.
