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 as opposed to 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.
- You gain time. No knife manufacturing, no knife changing, hence no waiting for temperature equilibration.
Cryo 35° Cryo 45°
The 45° knife is well suited for routine cryo sectioning.
The 35° knife allows you to section 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.
