    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： Multiwell filter comprising a filter plate having a plurality of wells, each including a support. Each well has a corresponding adjacent access port providing access to the corresponding feeding/receiver plate well, e.g. via a pipette. When the filter plate is positioned over a feeding/receiver plate having a plurality of wells, each well of the feeding/receiving plate aligns with and communicates with a corresponding filter plate well. Each access port provides access to a respective well in the feeding/receiver plate, and the wells in the filter plate are not centrally located with respect to the feeding/receiver plate wells, but are shifted in the x and y directions relative to the receiver wells in an amount effective for reducing or eliminating capillary holdup in the gap between the filter wells and the feeding/receiver wells. The wells in the feeding/receiver plate preferably are formed in a U-shaped bottom below each access port.

    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.

    摘要： The present invention provides an underdrain having an improved spout. The underdrain has particular utility in the construction of both single-well and microarray filtration devices. In a principal embodiment, the underdrain is characterized by its incorporation of a straight-walled, roughly-textured spout, the spout being provided with microhole(s) at a terminal end thereof for the discharge of fluid conducted through the underdrain. An array comprising several of such underdrains can be mated with a corresponding array of wells, with separation material (e.g., membrane material) provided therebetween. The resultant microarray filtration device can be used for conducting several fluid assays contemporaneously with, for example, good “pendant drop” control and low “cross-talk”.
