Abstract
A cell culturing device includes a plurality of trays that are stacked on top of each other, each of the plurality of trays having a floor and an upstanding encircling sidewall, the floor and the encircling sidewall of each tray bounding a space configured to hold a liquid cell culture medium, the plurality of trays comprising a top tray, a bottom tray and one or more intermediate trays disposed therebetween. The bottom tray and the one or more intermediate trays each have a first venting port extending upwardly from the floor thereof, each first venting port bounding a channel passing through the floor of the corresponding tray and being in fluid communication with an adjacent tray. The channel of the bottom tray is openly exposed so that a gas can flow from the space of the bottom tray through the channel of the bottom tray.
