Device, a system and a method for measuring permeability, in particular permeability of a fibrin clot

A system for measuring permeability of a material sample, comprising:

• a device comprising:
• an input tank configured to store fluid and to supply the fluid to a sample tank positioned below the input tank and configured to hold the material sample, such as to allow the fluid from the input tank to permeate through the material sample;
• a receptacle positioned under the sample tank to collect drops of fluid permeated through the material sample;
• and
• a device for measuring the mass of the drops collected in the receptacle and coupled with a controlling and monitoring device configured to store data on measured mass and measurement times;
• wherein the controlling and monitoring device is connected to a recording and analyzing device configured to record and analyze data in real-time.

A method for measuring material permeability, comprising the steps of:

• providing a device comprising:
• an input tank configured to store fluid and to supply the fluid to a sample tank positioned below the input tank and configured to hold the material sample, such as to allow the fluid from the input tank to permeate through the material sample;
• a receptacle positioned under the sample tank to collect drops of fluid permeated through the material sample;
• and
• a device for measuring the mass of the drops collected in the receptacle and coupled with a controlling and monitoring device configured to store data on measured mass and measurement times;
• and
• analysing the measured mass and measurement times for individual drops to determine the permeability of material stored in the sample tank.
