Abstract
A device and method for removal of liquid from the downstream side of a membrane or a well, such as a well of a multiwell plate. More specifically, the present invention is directed to a wicking structure, which channels droplets of liquid away from a membrane in communication with a plurality of wells. In the preferred embodiment, the wicking structure is placed in a manifold.
Claims2
A method of filtering a liquid sample contained in a plurality of sample reservoirs, comprising:
- causing said sample to pass through a membrane in communication with each of said plurality of sample reservoirs to form a plurality of respective filtrates, said membrane having a membrane surface, each of said plurality of respective filtrates forming at least one droplet on said membrane surface;
- directing each of said at least one droplet from said membrane surface to a collection chamber by absorbing said droplet from said membrane surface, wherein each of said at least one droplet is directed from said membrane by an absorbent for said liquid.
