Drop Profile and Measurement of

How does one trap drops at the glass/rubber interface  

FIGURE 9.25. Deposition of drops at a glass/elastomer interface by (a) injection (water) or (b) dewetting (PFAS). A film (1) squeezed between a rubber marble and glass thins down (2) and dewets (3). Note the dimple formed during drainage (2)  

FKiURE 9.26. Interference pat tern and profile of a highly flattened drop of water sandwiched between an elastomer and glass. Note the different scales on the two axes. (From P. Martin, P.
