WebTo adjust the pH of a sample: 1. Prepare diluted sample. Most dilutions media such as buffered peptone water or Butterfield’s phosphate-buffered dilution water, have a level of buffering capacity and is designed to help buffer the pH. A pH adjustment may not be required after dilution. However, this should be determined during verification. 2. WebA simple phosphate buffer is used ubiquitously in biological experiments, as it can be adapted to a variety of pH levels, including isotonic. This wide range is due to phosphoric acid having 3 dissociation constants, (known in chemistry as a triprotic acid) allowing for formulation of buffers near each of the pH levels of 2.15, 6.86, or 12.32.
