Theoretical Study on the Dynamic Separation of Two Microplates with an Intervening Liquid Meniscus

Abstract:

The dynamic separation of two parallel microplates with an intervening liquid meniscus is studied theoretically. The dynamic model considering the meniscus force and the viscous force between the plates in the separation process was developed. With typical simulation parameters, the magnitudes of various forces were compared before the separation of two parallel plates occurs. It was found that the meniscus force decreases gradually with the increase of separation distance. However there is a sudden jump of the viscous force before it gradually increases, then it decreases dramatically. The influences of various parameters on the separation time were investigated. It was found that the separation time increases with the mass of the upper plate, surface tension, viscosity and volume of the liquid. The separation time decreases with the initial distance and the contact angles of the liquid.
