Diamond knife, Cryo Dry, 45 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.

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.   Lead time ~ 6-10 weeks from receipt of your knife.

** Exchange - Trade-in any old diamond knife when you buy a brand new Diatome diamond knife for a significant discounted price.  If you want an exchange service, you will post your old knife to us and we will send it away to our supplier to be exchanged for your new knife.   

When placing an order, please write "change" if possible (ultra 45° to Cryo 35°, small knives to large ones, etc).  Lead time ~ 4-6 weeks from receipt of your knife
