Biological buffers, also known as good’s buffers, are substances used to maintain a stable pH level in biological systems such as cells, tissues, and biological fluids. These buffers resist changes in pH by absorbing or releasing hydrogen ions (H+) in response to acid or base challenges, thus helping to regulate the acidity or alkalinity of a solution.

In the biopharmaceutical and diagnostic industries, biological buffers are essential components used in various applications such as cell culture, protein purification, and enzyme assays.

They ensure optimal conditions for biological processes by providing a stable environment within a specific pH range, ultimately enhancing the reliability and accuracy of experimental results and product performance.
