Ralph - Long Glass Knifemaker


Long-edged glass knives are finding increasing application in histology for producing large area semi-thin sections of wax or resin-embedded tissue. The Ralph Glass Knifemaker is capable of producing 38mm wide knives using a single lever action to both score and break the glass. By replacing the steel knife of a microtome with a long glass knife, sections down to 1.55ยต can be cut.

The unit accepts both 25mm and 38mm wide glass strips, and produces a straight, uniform cutting edge across the entire width. Vernier marked controls enable a range of knives with different rake angles to be reproducibly made.
