ABSTRACT:
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).
