Abstract
A microplate assembly comprising a multi-well microplate, a plurality of vent caps and a porous vent film. The microplate includes a frame that houses a plurality of open wells in a rectangular array. Vent caps mount on the microplate to seal and vent the wells. When the vent caps are coupled to the wells, an interior volume is formed in each well. The wells function as a vessel for liquid samples that occupy predetermined spaces within the interior volumes. Each liquid sample remains within its predetermined space for all orientations of the microplate assembly. The vent cap comprises an array of well inserts. Each well insert comprises a sealing plug and a vent tube. A flexible perforated web interconnects the well inserts to each other. The vent tubes are fixed to the sealing plugs and terminate in a vent. A barrier formed from a plurality of nested flaps resiliently mounts on the vent tube to partially cover the vent and help inhibit the evaporation and loss of the liquid samples.
