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.

** Resharpened DiATOME knives undergo the same stringent optical checking and sectioning tests as new knives. If you are wanting a re-sharpened service, you will post your old knife to us and we will send away to our supplier.
The lead time for re-sharpening knives is ~ 10-12 weeks from the receipt of your knife.
