MULTIWELL TISSUE CULTURE ASSEMBLY WITH REDUCED MEDIA EVAPORATION

摘要

A multiwell tissue culture assembly comprises a plate and a lid. The plate includes a plurality of wells for receiving liquids therein. Upstanding side walls form the outside border of the plate. A ledge is spaced inwardly of the side walls and extends around the plate between the side walls and the wells. The lid is removably positioned on the plate and includes a substantially planar cover extending over the wells. A labyrinth passage is associated with the cover, the side walls, the ledge and the wells to permit air exchange between the wells and the external environment to maintain equalibration therebetween, but to partially prevent air entrance to the wells to minimize evaporation of liquids in the wells.
