ABSTRACT:
A separation-science medium support plate has a multiplicity of concentric, radially-spaced grooves located on an upstream side of the plate. The concentric, radially-spaced grooves each have two open ends that allow a groove to communicate, ultimately, with a radially-extending groove that has an opening located therein. The opening is disposed in the radially-extending groove towards the periphery of the support plate and allows a fluid to pass from the upstream side of plate to the downstream side. The plate lacks any openings for fluid passage other than the peripherally-located opening(s). A plate of this invention makes a centrally-deposited fluid droplet follow a highly tortuous path before passing through the peripherally-located opening(s), and this enables a separation-science membrane resting on the plate to become uniformly wet by the fluid.
