In
1989 J. C. Jésior (Ref. Jésior) demonstrated
considerably
reduced compression,
smoother
section surfaces and improved
structural
preservation thanks to the use
of
our ultra 35° knives.
In
the meantime, a large number of scientists have recognized the
advantages of 35° knives, in particular for sectioning Lowicryls and
non-homogenous specimens, as well as non-decalcified bone, dental
materials, etc.
The
ultra 35° knives are perfect for sectioning relatively soft materials
research specimens including metals and polymers,
as
well as hard specimens such as semiconductors, superconducting oxides,
catalysts, nano-crystalline ceramics, etc
The
ultra 35° knife has demonstrated it's usefulness as a standard knife
for the majority of applications in both biological
and
materials research.
The
ultra 35° knife (in the triangular holder)
with
a cutting range of 100nm - 2µm is used for dry sectioning of epoxy or
acrylic resin embedded biological samples, which need to be investigated
by element analysis and SIMS
. The gliding of the sections on the dry knife surface is facilitated
with the use of our Static Line II
ionizer.
