The Ultra 45° angle knives are used for routine sectioning (50nm - 500nm) of both biological and materials specimens. 

Cutting range: 50nm - 500nm.

For 3D reconstruction it is imperative not to loose a single section (M. J. F. Blumer et al., Journal of Neuroscience Methods 120, pp. 11 – 16, 2002).

The large Jumbo boat increase the distinct advantages of our Jumbo knives.

They allow:

• easy production of section ribbons (0.5 – 2 µm)

• no section loss

• no folding

• the same orientation of all sections

• easy collection of section ribbons

• multiple ribbons on one glass slide

• perfect for immuno-histo-chemistry.

This knife in the jumbo boat holder can be used for section series for 3D reconstruction, STEM
