How to prepare the buffer solution
Solid material for pH4.01, pH7.00, pH10.01 buffer solution are provided in a set of sachets. Glass jars or beakers are
recommended as the solution containers.
Take making the 250ml buffer solution of pH 7.00 as an example:
(1). Put the pH 7.00 buffer material (in the green sachet) in a jar (the volume should be no less than 250ml).
(2). Fill the jar with 250ml distill water.
(3). Place a glass stick in the solution, swirling it until the white powder dissolved.
(4). Store the buffer solution in the cool and dry place. Attach a label on it for further use.
(5). For the further calibration, Ensure that there is a constant supply of fresh buffer solution in contact with the probe.
Discard the solution after use.
