Wescor's Markhart Leaf Press, model LP-27

This leaf press was designed at the University of Minnesota.  The liquid sample is extracted directly to a filter paper disc.  The disc can then be inserted into a Wescor Vapor Pressure Osmometer or a C-52 Sample Chamber for determination of the osmotic potential.

Using this press simplifies the liquid extraction process and reduces errors due to concentration of the sample by evaporation.


  • Easy to use
  • Direct collection of sample for osmotic potential determination
  • Reduces errors due to evaporation
