Ultra

These knives are available with a 35° or 45° angle and in six edge lengths ranging from 1.5 to 4.0 mm. Ultra 45° The Ultra 45° angle knives are used for routine sectioning (30 nm - 200 nm) of both biological and materials specimens. They can also be used for ultrathin/semi-thin sectioning (50 nm - 1 μm). They are acknowledged to offer a good compromise between section quality and durability. Ultra 35° The 35° angle knives have proved advantageous for sectioning the Lowicryls and non - homogenous specimens as well as non-decalcified bone, dental material etc. They are also the choice for sectioning relatively soft materials research specimens, including metals and polymers, as well as hard specimens, such as semiconductors, superconducting oxides, catalysts and nanocrystalline ceramics. Cutting range: 30 nm - 200 nm. This knife in the triangular holder can be used for cutting dry sections (100 nm to 2 μm) of epoxy or acrylic embedded biological specimens for elemental analysis and SIMS.
