Buffer solutions

Product information "Buffer solutions"
Ready to use calibration solutions for all pH-electrodes (50 ml in a plastic screw-capped bottle)

In order to avoid accidental mixing up or mistake by calibration, the solutions are coloured differently
pH 4,00 ±0,02 (20 °C), red
pH 7,00 ±0,02 (20 °C), green

The calibration solutions are ready to use. There is no need to dilute them or process them. Just add enough buffer solution to a small beaker or any other suitable container, rinse the electrode with distilled water, immerse the electrode in the buffer solution and calibrate according to the instruction of your instrument.
