Bluelab® pH 4.0 Solution, 20 mL Sachet

Bluelab® Calibration Solution 20 ml Sachets

The Bluelab calibration and conductivity standard solutions are essential for use with all Bluelab products for the calibration of pH and testing the cleanliness of the Bluelab Conductivity/Temperature probe.

Bluelab solutions are manufactured specifically for Bluelab products and are referenced to high laboratory standards to ensure your Bluelab
products last longer and maintain accuracy.

Bluelab's EC/CF equipment does not need calibrating as they are all factory calibrated here at Bluelab. The CF27.7 (EC2.77) solution is used
as a reference or checking solution to ensure you have adequately cleaned the EC/CF probe.

Contamination between solutions can easily occur, which will affect the validity of the calibration. Bluelab recommend that the solutions are
de-cantered into a smaller vessel and the contents discarded when the calibration process has been completed.

To ensure solutions remain accurate:

  • Avoid cross-contamination
  • Decanter into a smaller plastic cup
  • Discard sample after use
  • Store in a cool dark place
  • Store with lid secured tightly
  • Keep out of reach of children
