摘要： 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.

摘要： A feeding tray for retaining a nutrient medium is provided for use with a multiwell filter plate. The feeding tray includes an inclined support surface surrounded by walls that retain nutrient medium on the support surface. The support surface is inclined away from an area for introducing nutrient medium into the feeding tray toward an area for draining the feeding tray of nutrient medium.

摘要： A multiwell test apparatus comprising a multiwell filter plate and having wells that fit within the wells of a single or multiwell receiver plate is provided. The multiwell filter plate also is provided with posts which fit into holes of the receiver plate. The posts and holes are shaped to fix the position of the wells of the multiwell filter plate within the well(s) of the receiver plate and to permit controlled lateral movement of the multiwell filter plate when it is partially removed from the receiver plate so that excess liquid on the wells of the multiwell filter plate can be directed into the well(s) of the receiver plate.

摘要： A multiwell test apparatus formed of a multiwell filter plate having a plurality of wells and a first feeding plate and a second receiver plate is provided. The wells of the multiwell filter plate each have an open bottom surface to which a membrane is attached, at least one first access hole providing access to the feeding/receiver plate below, a pair of alignment pins designed to fit alignment holes in the feeding/receiver plates in a particular arrangement. The first feeding plate is a single well plate or a multiwell plate used solely for feeding. The second receiver plate is a multiwell plate having the same number of wells as the filter plate and aligned so as to receive the wells of the filter plate therein used as the assaying plate. The use of alignment holes in the feeding/receiver plates and alignment posts in the filter plate ensure precise alignment of the plates when together.
