Goniometer

roll2rollThe lab made Goniometer utilizes a dispensing system in which fluid is loaded into a syringe and expelled using a precise pressure controller onto the sample surface which is placed on a translational stage. A CCD camera is used to capture the fluid drops and the angle is measured with an image processing software. This instrument supports compatible materials and fluids, and eases dispensing with an adjustable head and needle size for various materials viscosity.
