Patent ID: 7439056

Claim:
A device for arraying a biological material comprising: a base plate; a first removable member defining a plurality of first orifices therein, having a plurality of first walls bounding the plurality of first orifices, the first removable member being in self-sealing contact with the base plate for defining a plurality of first wells therewith corresponding to respective ones of the plurality of first orifices to define a first array, the first removable member being adapted to repeatedly self-seal on the base plate; a second removable member defining a plurality of second orifices therein, having a plurality of second walls bounding the plurality of second orifices, the second removable member being in self-sealing contact with at least one of the base plate and the first removable member for defining a plurality of second wells therewith corresponding to respective ones of the plurality of second orifices to define a second array, the second removable member being adapted to repeatedly self-seal on at least one of the base plate and the first removable member, wherein at least one of said plurality of second orifices is smaller than at least one of said plurality of first orifices; at least one registration element adapted to align the base plate, the first removable member, and the second removable member with one another.
