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”.

摘要： The present invention relates to a multiwell plate having a series of wells, each well having an inner bore, an open top and a bottom, the bottom being sealed with a liquid permeable filter, and an insert contained within the inner bore of each well, each insert having an outer dimension the same or larger than that of the inner bore and a through bore of a dimension less than that of the outer dimension of the insert. The use of inserts allows one to take a standard one-piece plate design with a heat sealed membrane and arrange for a universal plate format. The insert may act as a base for an extension plate that can be adhered, heat sealed or overmolded over the plate top and insert top to form a deep well plate. The plate conforms to the Society of Biological Standards Microplate Standards. Additionally, the inserts may be configured to give one a different well diameter (smaller, tapered, etc), to include various media such as chromatography resins, to include multiple layers of membrane and the like. A variety of inserts may be used in the same plate to create a minilab on a plate that is capable of conducting several steps of a process on the same (e.g (e.g. filter, wash, bind, elute, label, etc).
