Abstract
A rectangular container having a divider at one end of the container. The divider separates the container into a large processing region and a second region from which the solvent fluid is drained from the container. The divider acts as a weir over which the solvent flows from the processing region into the second region. Contaminating particles which fall onto the surface of the solvent and are momentarily trapped by surface tension are quickly removed from the processing region by the overflow action into the second region.
