Abstract
Arrays of biological tissue can be created by removing cores from regions of interest in a series of donor blocks of embedded tissues. The cores removed are placed in a regular array in a recipient block. This is typically done with two different punches, one for obtaining the cores of interest and the other for creating the receiving holes in the recipient block. The present invention comprises such a system including a single z axis, with a mechanism for automatically changing two or more punches in and out of a holder on the z axis.
