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. Webextreme sample pH Can prevent the correct pH adjustment (of the sample) by the reagents. Sample pretreatment may be necessary. A pH range of 2–10 is recommended. Silica …
