Labnox® pH Buffer Solution pH 4.00 ph 7.00 ph 9.20 | pH Liquid Calibration at 25°C as per Quality Standards (200 ML)

Description

Using a high-grade buffer to calibrate your meter before each use is the only tried-and-true way to get the most accurate results every time. pH calibration solutions, also called pH buffers, are an essential tool when measuring pH with a pH meter and electrode. While some users will try to make their own solutions to save money, these homemade buffers are not accurate or stable, and in the end they will waste time and interfere with the accuracy of your results.Our Labnox pH buffer is much more stable and is resistant to change. pKa is a number that describes the acidity of a particular molecule. Types of Buffers : Buffers are broadly divided into two types – acidic and alkaline buffer solutions. A pH buffer is an aqueous solution consisting of a weak acid and its conjugate base or vice versa that lets the pH change to be minimal when a small amount of a strong acid or a strong base adds to it.
