Leica Glass Knife Maker

Leica GKM


The glass knife maker provides the ability to manually create glass knives used for ultramicrotomy or histology. Useful in TEM and light microscopy, strips of 25 mm wide glass are scored and broken into squares, which are then broken in half to produce two triangular knives, one with a straight, sharp edge used for sectioning. The balanced break method is used in this machine.
