pH 4 Meter Buffer Solution 2 oz

A pH meter needs to be calibrated before each use, and this is one of the solutions necessary.
Directions: Rinse the electrodes with a small portion of buffer, then standardize in enough fresh buffer to cover the tips of the electrodes. The buffer cannot be reused. Discard after use.
