ultra 35° ultra 35° Jumbo ultra semi
In 1989 considerably reduced compression, smoother section surfaces and
improved structural preservation thanks
to the use of our ultra 35° knives was
demonstrated (J. C. Jésior, Scanning
Microscopy Supplement 3, pp. 17 – 153,
1998).
In the meantime, a large number of
researchers have recognized the advantages of 35° knives, in particular for
sectioning biological specimens of all
kind, non-homogenous specimens, non
decalcified bone, dental material, etc.
The ultra 35° knives are perfect for sectioning relatively soft materials research
specimens including metals and polymers, as well as mixed specimens such as
polymers filled with nanoparticles, brittle
materials such as catalysts, crystals,
semiconductors, etc (G. Mahon et al.,
Microscopy Research and Technique, Vol.
31, pp. 267 – 274, 1995, S. R. Glanvill,
Microscopy Research and Technique, Vol.
31, pp. 275 – 284, 1995, P. Swab et al.,
Mat. Res. Soc. Symp. Proc. Vol. 115, pp.
229 – 234, 1989, P. Schubert-Bischoff
et al., Microscopy and Microanalysis,
proceedings, page 359, 1997).
The ultra 35° knife has demonstrated
it’s usfulness as a standard knife for the
majority of applications in both biological and materials research.
The ultra semi knife serves for alternating sectioning ultrathin/semithin, for rather thick sections (for exemple 200-300nm 3D reconstruction, etc.
