Useful pH range of Biological Buffers
In order to study biological processes in laboratory, researchers often need to use buffers to maintain the correct pH during the experiment they are performing. Each buffer is effective on keeping the pH stable in a specific pH range, therefore you must define your optimal pH before choosing your buffer.
