Sapphire knives may be used with all vibrating or oscillating types of microtomes for applications in Neuroscience, Electrophysiology/Histology. They offer several advantages over conventional razor blades.

Improved section quality
Sapphire knives provide significantly improved section quality over razor blades, particularly in electrophysiology applications. Distortion-free sections are possible at section thickness down to 5Micrometre.

Smoother surfaces for histology
By making a cleaner cut, the surface cells remain alive and intact, so the researcher can more easily explore the live and responsive interior cells. The clean cut produced by the sapphire knife results in smoother surfaces, making it easier to follow small labelled elements.

Thinner sections are possible with a vibrating microtome
The sapphire knife fits tightly in knife holders of most vibrating microtomes. Now your vibrating microtome is an attractive alternative to the cryostat when you need thin sections of fresh or lightly fixed tissue for:

  • Fluorescent labelling
  • Autoradiography
  • Immunohistochemistry

Extend the life of your knife
Used properly, your sapphire knife edge will last for thousands of sections. The knife is easily cleaned of glue and tissue and.
Knife edges are resharpenable and are restored to original condition. Approximate time for sharpening and shipping overseas is one month.

Use older specimens
Sapphire knives easily section through myelination in mature specimens.

Material: synthetic single crystal sapphire
Edge length: 40mm
