Diamond knife, Ultra, 35 deg.
Diamond knife, Ultra, 35 deg.
The Ultra knives are available with 35 and 45 degree angles in either Wet or Dry styles. The optimal thickness range for cutting with these knives is between 30 - 150nm. Sizes range from 1.5 - 4.0mm as a standard. Other sizes are available upon request. All of the knives are tested within a thickness range of 30 - 150nm. Whether your needs are biological or materials related, in EM or LM, we have a knife to suit your needs.
Ultra 45°
Recognized as the knife for routine sectioning. It is a good compromise between section quality and durability.
The 45° knife is recommended for the sectioning of extremely hard and brittle materials such as ceramics. In this domain, it has replaced the formerly recommended 55° knife.
Ultra 35°
The capabilities of the 35° diamond knives have been shown in two publications by J.J?sior (Ref 3, 4). He proved markedly reduced compression, smoother section surfaces and better structural preservation with the use of our 35° diamond knives.
In the meantime a great number of scientists have noticed and recognised the advantages of the 35° knives for the sectioning of Lowicryls, inhomogenous samples such as undecalcified bone, dental materials, etc.
The 35° knives have proved advantageous in the sectioning of soft industrial samples such as metals and polymers, as well as for hard and brittle samples, for example semiconductors (Si, GaAs, etc), superconducting oxides, nanocrystalline ceramics.
The use of 35° knives leads to reduced compression in soft samples and to less breaking in hard and brittle samples.
** 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 it away to our supplier.
The lead time for re-sharpening knives is ~ 10-12 weeks from the receipt of your knife.
A diamond knife resharpened by DiATOME is the same high quality as a new one!
** 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).
