But that would be difficult to measure and is not the case :) Its the contact angle against the surface of some kind. Paper, plastic, metal, oil etc. The fall I refered to is in the highspeed system. When the droplet releases from the pipet it falls down to the surface. There are a wish from my employer to measure the drop under the fall to make a more exact measure of the volume on the aplied drop before impact at the surface. The surface can be high absorbing papers. /Peter
