Fixing device for fixed table type PH meter

Technical Field

The utility model relates to an experimental device technical field especially relates to a fixing device for fixed desk-top PH meter.

Background

A PH meter is a common analytical instrument used to determine the PH value of a solution. The PH meter operates on the principle of a galvanic cell, the electromotive force between two electrodes of which depends on nernst's law, both on the properties of the electrodes themselves and on the concentration of hydrogen ions in the solution. There is a corresponding relationship between the electromotive force of the primary cell and the hydrogen ion concentration, and the negative logarithm of the hydrogen ion concentration is the PH value. The pH of the culture medium has a very significant effect on the growth of microorganisms in biological experiments. For example: for the synthesis of penicillin, the most suitable pH range is 6.5 to 6.8, so that a pH meter is an essential instrument in the liquid preparation process of biological experiments.
