A microarrayer apparatus for constructing arrays of biological material from donor cores obtained from at least one donor block and placing the donor cores in an embedding medium carried by at least one recipient block. The apparatus includes a donor punch, a recipient punch, and a stylus mounted for independent coaxial movement along a common punch axis. The recipient punch cooperates with the stylus when ejecting a donor core from the donor punch to minimize deformation of the donor core.
