DiATOME® ultra Diamond Knives Features:

  • 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

ultra 35 Wet

ultra 35° Wet

The ultra 35° knife is the standard knife for the majority of applications in both biological and materials research.  The 35° blade angle is ideal for sectioning biological specimens ranging from organ tissues to un-decalcified bone and dental material. In the field of Materials Science, the ultra 35° excels at sectioning relatively soft metals and polymers, as well as nano-particle filled polymers, brittle metals such as catalysts, crystals and semiconductors. Section thicknesses range from 30 to 200nm. Standard boat. Available in blade widths from 1.5 to 4.0mm.

ultra 45

ultra 45°

Like the ultra 35°, this is a general use knife with good sectioning and durability characteristics. The 45° blade angle knife replaces the old 55° and allows for better sectioning of ceramics and other hard, brittle materials. Section thicknesses range from 30nm to 200nm. Standard boat. Available in blade widths from 1.5 to 4.0mm

ultra 35 dry

ultra 35° Dry

The ultra 35° knife (in the triangular holder) with a thickness range of 30-200nm is used for dry sectioning of epoxy or acrylic resin embedded biological samples, which need to be investigated by element analysis (Ref. Edelmann) and SIMS (Ref. Guerquin-Kern).
