Diamond knives supplied by Agar Scientific are manufactured from high purity, gem quality diamonds providing a sharp, durable edge for sectioning applications in biological and materials sciences. Diatome manufacture a range knives specifically design for cryo applications, these allow:

  • Thinner cryo sections
  • Perfect cryosections from ultrathin to semi using the same knife
  • Minimal compression and best structure preservation
  • Highest quality diamonds and optimal crystal orientation guarantee perfect ultrathin sections and a durable cutting edge
Type Uses
Cryo For cutting in the cryo-ultramicrotome
Cryo immune A large diamond platform facilitating pick-up of cryo sections from sucrose infiltrated samples (Tokuyasu)
Cryo 25°  Low angle knife for sectioning frozen hydrated samples (CEMOVIS)
Ultra AFM & cryo AFM Knives for generating absolutely smooth and flat surfaces of biological and technical samples for the examination in AFM

A re-sharpening and exchange service is also available. Our sales team will be happy to quote for these services.
