The Diamond Trimming Tool:

trimtool 20 and trimtool 45

Finally, one trimming tool for all of your trimming needs, be it at room or cryo temperatures. The trimtool series supercedes the cryotrim and ultratrim lines of trimming tools. Resharpening is still available for these lines.

For successful ultramicrotomy in biology and materials science, precise trimming is mandatory.

The Diatome trimming blades trimtool 45 and trimtool 20 will fulfil all your trimming requirements, allowing quick, easy and accurate trimming at both room and cryo-temperatures.

Due to the extreme sharpness of our diamond blades, less mechanical damage is applied to the sample during trimming.

Very shiny sample faces and precise sides are the result.

The trimtool 45 produces pyramidal sides with an inclined angle of 45° and the trimtool 20 produces pyramidal sides with an inclined angle of 20°. The trimtool 90 aids in the FIB cutting of biological and technical sample blocks, trimming the 90° inclined blocks sides and well as the surface of the block.

Area of application

Room Temperature:

  • Epoxy or acrylate resin embedded biological samples
  • Metals
  • Polymers
  • Nanoparticles in polymers
  • non-embedded brittle samples

Cryo Temperatures:

  • Sucrose infiltrated and frozen hydrated bilogoical samples
  • Soft polymers

The trimming procedure



Also Available:

The EM Trim Diamond Cutter for the Leica "EM-Trim"

These cutters are used exclusively in the Leica EM Trim and are available in either 6 or 12 mm diameter. These blades allow for parallel edges of the complete block which is mandatory for successful sectioning.

Your benefits of working with Diatome

Free customer service

Sectioning tests with biological and material research specimens of all kinds.

We send you the sections along with the surfaced sample, a report on the results obtained and a recommendation of a suitable knife.

Complete discretion when working with proprietary samples.

Re-sharpening and reworking service

A re-sharpened Diatome diamond knife demonstrates the same high quality as a new knife.

Even knives purchased in previous years can continue to be re-sharpened.

All knives can be reworked into another type of knife for no extra charge, e.g. ultra to cryo or 45° to 35°.

Exchange service

Whenever you exchange a knife we offer you a new Diatome.
