Claims13
Apparatus for removing cells from cell culture apparatus having a plurality of discs mounted on a central shaft, the cell removing apparatus comprising a substantially shaft-like member having mounted thereon substantially perpendicularly to the axis of the shaft-like member a plurality of spaced apart contacting members, each contacting member adapted to contact at least part of the surface of a disc, each contacting member having two arms, each arm attached separately to the shaft-like member, the arms being joined a distance removed from the shaft-like member whereby the contacting member is substantially triangular in shape having its base at about the shaft-like member and its apex a distance removed from the shaft-like member, and each contacting member being moved directly upon rotation of the shaft-like member.
In a multiplate propagator comprising a substantially cylindrical vessel having a plurality of spaced apart parallel discs on which discs cells are grown, the discs mounted on a rotatable shaft within the vessel, the improvement comprising a second shaft pivotably mounted within the cylindrical vessel, the second shaft having mounted thereon contacting means adapted to contact at least part of the surface of a disc upon pivotal movement of the second shaft whereby cells are removed from the surface of the disc, the contacting means comprising a cell contacting surface having means for laterally reinforcing the cell contacting surface.
