A friend was pondering this. Think, with a big PVC pipe with a sealed flat bottom, the solvent layer would be really long and tall and easy to minimize the size of the layer left in the container after a pull.

Plus, think of the surface area contact that the solvent would have with the soup if you capped the top and turned it on its side.

Would be absolutely ideal, except I'm pretty sure the chemicals would eat right through that pvc.
