Dutrochet osmometer

The phenomena of plasmolysis and turgor pressure in a plant cell, or hemolysis in red blood cells, are due to water exchanges between the intra- and extracellular environments. These exchanges are governed by the laws of osmosis. Water movements are the result of differences in osmotic pressure between the two sides of the membrane.

To simulate these exchanges, you can use the Dutrochet osmometer device with a permeable membrane such as Parafilm (ref. 703344) or stretchable food wrap (cellophane) and a sucrose solution (ref. 107611).

Dutrochet's osmometer consists of:
- 1 glass tube with a diameter of 5 mm
- 1 glass bulb (H x Ø): 65 x 40 mm
- 1 container
