NTEC - Surface Energy Testing 

The following surface energy equipment is available for testing as per client request, or to specific specifications.


Dynamic vapor sorption (DVS) Equipment:

DVS is a technique that measures how quickly and how much of a solvent is absorbed by a sample: such as dry aggregate filler absorbing water. It does this by varying the vapor concentration surrounding the sample and measuring the change in mass which this produces.


Contact Angle Goniometer:

This is used to to measure the static contact angle and advancing & receding contact angles. Using this we can determine the ratio of cohesion vs adhesion.


Dynamic Contact Angle Analyser:

This is used is measure the dynamic contact angle between a liquid and solid. If the forces of interaction, geometry of the solid and surface tension of the liquid are known the contact angle may be calculated


Micro Calorimeter:

This is used to determine the changes in energy of a system by measuring the heat exchanged with the surroundings during an exothermic, or endothermic reaction.
