pH Buffer Solution Powder x 3

$6.95

Three buffer solutions packets are included.

Used for calibrating pH meters. Each buffer solution powder makes up a 250ml buffer solution. These are essential for pH meters that get a lot of use or haven't been used for a while. Over time pH meters will become less accurate, recalibrating ensures the meter is accurate again. Eventually the pH meter probe will need to be replaced but these buffer solutions will prolong the life of the probe also.

 

The three buffers are a pH of:

- 4.01

- 7.00

- 10.01

 

Make sure to use deionised water to make up your buffer solutions and stir until powder is completely dissolved.
