UltraTrim 45°

Finally, one trimming tool for all of your trimming needs 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.

  • Rapid and precise trimming
  • Shiny block faces and pyramidal sides
  • Sample surface aligned with the cutting direction
  • Durable cutting edge

The DiATOME trimming blades Trimtool 90, Trimtool 45 and Trimtool 20 will fulfill all your trimming requirements, allowing quick, easy and accurate trimming at both room and cryo-temperatures.

A well trimmed sample is a precondition for perfect section ribbons. 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.
