Made of stainless steel, these matrices are sturdy and can be heated, chilled, autoclaved, scrubbed and stand up to rigorous daily use. Coronal matrices have the additional feature of a mid-line sagittal cut to facilitate splitting of the left and right hemispheres. Sections can be as fine as 1 mm.
The olfactory/spinal/notch is cut into each matrix.
