FlairForm pH Buffer 4.0 - 250ML / 1L | Calibration Solution for pH Meters

pH meters must be regularly 'calibrated' (i.e. adjusted for accuracy) using standard pH buffer solutions which are made to an internationally agreed recipe.

• Flairform's buffers are formulated with NIST specified ingredients.
• Stabilised to resist algae or growth formation:  Growths' can contaminate pH electrodes which in turn affects the “slope” value beyond the software’s ability to compensate.
