Principle of the permeability system:
 
The function of the system is shown on the picture. On top of the tissue you have a defined volume of liquid. The liquid will be exposed to pressure as a stimulus. The pressure gradient between upper und lower part of the examination box (main unit) will force the tissue to pass the liquid. It is still possible to stimulate the tissue not by pressure then by a different liquid stimulus injected from the upper side. The loss of liquid will be recorded by the liquid level sensor and this starts the isovolumetric level control to refill passed medium. The volume on top of the tissue is known as well as the volume above the tissue. The volume gap between upper and lower volume represents the volume staying in the tissue. All parameters and data are documented in a data file, that is very easy to convert in a diagram.

The various ways to stimulate the tissue, the possibility to integrate a camera system and the consistent documentation of parameters and data allow to get high quality facts of the tissue. This process is the platform or baseline for your special requirements. Ask us for more information about customizing.
