Abstract
An automated biological cell harvesting apparatus including a fluid dispensing head adapted to move to a lowered position and dispense fluid from a plurality of spray ports, a fixed upper tray positioned beneath the fluid dispensing head for supporting a biological filter plate of the type defining a plurality of fluid permeable wells therein, a vertically movable lower tray adapted to move from a lowermost position to a raised position in engagement with the upper tray. A controller is provided for dispensing fluid from the fluid dispensing head into the wells of the filter plate, and raising the lower tray into its raised position in engagement with the upper tray and then creating a vacuum between the lower tray and the upper tray to draw the fluid from the filter plate supported on the upper tray into the lower tray for collection in a microplate with a corresponding number of wells or, in the absence of a microplate, for removal of the fluid from the lower tray to a remote common waste collection vessel.
