Phosphate Buffers with pH ranging from 5.8-8.0 (at 25ºC) can be prepared. It is often convenient to prepare a concentrated solution (10X or 20X) taking into account that upon dilution the pH increases slightly.

This product is a 20 times concentrated solution of PBS. Upon dilution, the pH will be 7.4 (25ºC), which is suitable for most applications.
