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).

Ultra type Key features

  • Highest quality diamonds and optimal crystal orientation guarantee perfect ultrathin sections and a durable cutting edge.
  • Section pick-up is facilitated as the boat is horizontal allowing the water to completely fill the boat all the way round.
  • A hydrophilic surface makes it easy to wet the cutting edge, even with low water level.
