ABSTRACT:
A feeding tray for retaining a liquid nutrient liquid is provided for use with a multiwell filter plate. The feeding tray includes a flat support surface surrounded by walls which retain liquid on the support surface. The flat support surface includes protrusions positioned to contact the membrane portion of a multiplicity of wells of the multiwell filter plate when the multiwell filter plate is removed from the feeding tray. These protrusions remove residual liquids from the bottom of each filter well thereby minimizing cross contamination in subsequent processing steps. Additionally, it may contain one or more baffles, in lieu of or in addition to the protrusions for controlling liquid movement during handling.
