L-250 pH Meter Buffer Solution Dispenser

Product Description: Usage of pH meter buffer solution: The 250mL buffer solution can be used multiple times. The amount required is just enough to fully submerge the glass electrode. Used buffer solution should be discarded and not reused. Store the remaining portion in a cool, dry place at 20-25°C. After prolonged use, the asymmetry potential of the pH meter electrode may change significantly, so regular calibration is necessary.
