OSMOMETRY


 

KNAUER osmometer Osmomanometer

 

Different types of osmometry measurements are done in the lab :

  • experiments in presence of a stressing agent (PEG or dextran) (Parsegian VA et al., Methods Enzymol, 127 :400-416,1986).
  • experiments with a classical osmometer ; the pressure detector measures the osmotic pressure of the sample.
  • experiments with an home-made "osmomanometer", to measure the pressure with a simple hydrostatic effect (E. Raspaud).
