Standard solutions: Because of the specific concentration's accuracy or the pH-value, the standard solutions function as a calibration for other solutions. A manufacturing specification and a strong monitoring stipulate the production of these solutions. You can acquire them ready-made! Buffer solutions can be used for calibration of measuring instruments, to pre-diluting samples or to stabilize chemical reactions. They are able to keep the pH-value constant, despite of addition of acids or bases. Even a bacterial invasion has no influence on the buffer solutions.
