2. Fill the far with 250ml distill water.
3. Place a glass stick in the solution, swirling it until the white powder dissolved.
4. Store the pH buffer solution in a dry place with the temp. of 20-25oC. Attach a label on it for further use.
5. For the further calibration, Ensure that there is a contant supply of fresh buffer solution in contact with the probe. Discard the solution
