The TCKG Organ/Tissue Chamber consists of two main cells, one is a large diamond-shape for containing the preparation and the other is a smaller oval-shaped cell where nerve ends are arranged for making electrical recordings. These two cells are separated by a removable acrylic partition. The bottom edge of this partition can be fashioned to leave a small arch through which nerve bundles can pass through for grease gap recording methods. The larger cell is normally pre-filled with an inert self-curing silicone rubber substrate to allow various types of preparations to be pinned in place. The smaller oval cell is supplied with a small pedestal on which a small pane of mirrored glass is used as a substrate to separate nerves from a nerve bundle with the aid of a dissecting microscope arranged over the cell.
