Description

The blue bottle experiment is a model experiment for a organic redox system. The redox indicator methylene blue is reduced by glucose to its colourless form which is then oxidised by air to form again the coloured version. The air is led into solution by a pump. Additional glucose in solution will then reduce it to its colourless form. The process is reversible. In this experiment a automated version with a two-point control system is used.
