Diamond knife, Cryo Dry, 25 deg.

DiATOME Cryo diamond knives may be used for all low temperature situations, such as sectioning of cryo-protected specimens, frozen hydrated specimens and industrial samples such as polymers and rubber.
There are numerous advantages to our Cryo diamond knives compared with glass knives:

There are numerous advantages to our Cryo diamond knives compared with glass knives:
  • They produce thinner sections
  • Ultrathin and semithin sections with the same knife
  • Easy to produce long ribbons of sections
Less compression and greater uniformity of sections
  • Time saving. No knife manufacturing, no knife changing, hence no waiting for temperature equilibration.
  • Diamond is the best temperature conductor - better than gold. No waiting for temperature equilibration
Cryo 25°
The Cryo 25° knife is designed for sectioning frozen hydrated specimens. The 25° angle results in the least possible compression and the best structure preservation.

Cryo 35° and Cryo 45°
The 45° knife is well suited for routine cryo sectioning.
The 35° knife allows sectioning with considerable reduction of mechanical damage to the specimen (up to 20% less compression as compared to the 45° knife) and, in turn, better structural preservation of most frozen samples (Ref 6, 7, 8).
The triangular holder for dry sectioning and the boat for the sectioning with a liquid (DMSO/water and others) are made of a special copper/nickel alloy. They both guarantee excellent cold or heat transmission.
The seal is made of a cold-resistant epoxy resin.
