trim 45, trim 20 and trim 90

Precise trimming is mandatory for successful ultramicrotomy of biological and material samples. The trim series of diamond blades allow for quick and accurate trimming. Due to the extreme sharpness of our diamond blades, less mechanical damage occurs to the sample during trimming. Very shiny sample faces and precise sides are the result. The trim 45 produces pyramidal sides with an inclined angle of 45°, the trim 20 pyramidal sides with an inclined angle of 20°, and the trim 90 pyramidal sides with an inclined angle of 90°. Triangular holder.

The DiATOME® EM Trim Diamond Cutters are used exclusively in the Leica® EM TRIM and EM TRIM2 and are available in either 6 or 12mm diameter. These blades allow for parallel edges of the complete block which is mandatory for successful sectioning.
