DiATOME Diamond Knives
DiATOME knives are compatible with all ultramicrotomes. The boat is designed in such a manner that the water is horizontal when the clearance angle is set. This results in a stationary water surface and good reflection.

The surfaces of the DiATOME diamond knives are hydrophilic. This property allows an easy wetting of the cutting edge, even with a very low water level (important for sectioning Lowicryls and other hydrophilic embedding media, as well as for water sensitive samples).

Cryo type Key features

  • Thinner cryo sections.
  • Perfect cryosections from ultrathin to semi with 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.
