This sample exhibited an equilibrium water contact angle of zero degrees, but the spreading is not instantaneous. The FTÅ200 can measure this spreading time. The following figures illustrate the drop profile at various times. The resultant contact angle and base width is also graphed. Differing amounts of surfactant in the resin would cause the drop to spread at different rates. To do comparative work of this nature, the drop volume should be standardized to within, say, 10% on each sample. The pump forms a pendant drop on the tip which is allowed to grow until its bottom touches the surface, at which time the drop detaches from the tip and forms a sessile drop.
