ultra knives and their applications


• Highest quality diamonds and optimal crystal orientation guarantee perfect ultrathin sections and a durable cutting edge • Section pick-up is facilitated as the boat is horizontal allowing the water to completely fill the boat all the way round • A hydrophilic surface makes it easy to wet the cutting edge, even with low water level

Special boat Application


• Soft industrial samples such as metals and polymers • Hard and brittle samples such as semiconductors, superconducting oxides, nanocrystalline ceramics


• Alternating sectioning ultrathin/semithin


• Sample surfacing for AFM


• Section series for 3D reconstruction, STEM


• Similar to ultra 35, features a larger boat.


• Compression-free sections • Best structure preservation

* Product Codes shown are for new knives. To order a resharpened knife, add “R” to the Product Code that corresponds to your knife. Example: Product Code 15-ULR = Resharpened ultra 35˚ 1.5mm Knife.


Ultra 35˚, 45˚, and ultra semi can be exchanged. To order an exchanged knife, add “E” to the Product Code. Example: Product Code 15-ULE = Exchange of an ultra 35˚ 1.5mm Knife.
