Abstract

A fluidic device includes a fluidic module with a first fluid chamber and a second fluid chamber closed with the exception of a fluidic connection to the first fluid chamber. A drive is formed to impart the fluidic module with a first rotation at a rotational frequency below a rotational frequency threshold at which liquid is pneumatically held in the first fluid chamber and does not enter the second fluid chamber. The drive is further formed to impart the fluidic module with a second rotation at a second rotational frequency above the rotational frequency threshold at which a liquid column created in the first fluid chamber becomes unstable and the liquid enters the second fluid chamber.
