The optimal thickness range for cutting with these knives is between 30-150nm. They are available in sizes ranging from 1.5 mm-4.0 mm as a standard. Other sizes are available upon request. All of these 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 35° Wet: The capabilities of the 35° diamond knives have been shown in two publications by J.Jésior (Ref 3, 4). He proved markedly reduced compression, smoother section surfaces and better structural preservation with the use of our 35° diamond knives. In addition a great number of scientists have noticed and recognized 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. We can claim that the 35° diamond knife has proved it's capability as a routine knife for many applications.
