Abstract: An adapter plate transforms a vacuum manifold designed for standard multi-well plates that are commonly used in biochemical laboratories into one that can be used for columns such as chromatographic columns, filtration columns, and the like. The plate contains an array of male-female-type complementary connectors, each connector fitted with a removable plug that seals the connector off when not in use. The plate thus allows the manifold to be used for as few as one column or any number up to the total number of connectors in the plate.

Abstract: A gel filtration plate designed to remove unincorporated dye terminator from a series of reaction mixtures in a nucleic acid sequencing operation is joined to an injection plate designed for insertion into a sequencing apparatus through an adaptor assembly that allows the two plates to be centrifuged together, thereby simultaneously purifying the reaction mixtures and collecting them in the receptacles that will be placed directly in the sequencer. The adaptor avoids the use of an intermediary collection plate and the need to transfer reaction mixtures from each well of the collection plate to each well of the injection plate.
