All calibration procedures assume that the labeled values of the calibration buffers are correct, but buffer values can change over time and so can your results. Therefore it is essential to have reliable ORP buffers on hand. Hamilton ORP buffers are stable for 2 years even if they have been used. The growth of fungus and micro-organisms is prevented.
