buffer values can change over time and so can your results. A complete range of patented buffer solutions provides pH stability up to 5 years, something never achieved before.
The pH buffers 9.21 and 10.01 are even stable in air. High buffering capacity provides rapid, stable
calibration. The growth of fungus and micro-organisms is prevented.
