These knives are available in 35, and 45 degree angles. The optimal thickness range for cutting with these knives is between 30 and 150 nm. They are available in sizes ranging from 1.5 to 4.0 mm as a standard. All of these knives are tested within a thickness range of 30 to 150 nm.
The 45° recognized as the knife for routine sectioning
The 35° diamond knives have been used for reduced compression, smoother section surfaces and better structural preservation. Also these knives have proved advantageous in Lowicryls, inhomogenous samples such as undecalcified bone, dental materials, 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 ultra 35° knife (in the triangular holder) with a cutting range of 100 to 2 µm is used for dry sectioning of epoxy or acrylic resin embedded biological samples, which need to be investigated by element analysis. The gliding of the sections on the dry knife surface is facilitated with the use of our static line II ionizer.
The ultra diamond knife is now available in Jumbo with 35° and 45° angles and in 2.0 and 3.0 mm sizes.
