Function and Applications

To the demonstration and observation of osmotic processes.
The chamber can be build up and cleaned without problems. Between two sealing rings arbitrary semipermeable membranes can be fixed. A measurable rise is achieved by the big boundary surface of differently concentrated solutions very quickly in the capillary tube. For the readout of the altitude a scale can be put on the capillary tube.
