DiATOME® Diamond Knives for CEMOVIS
(Cryo-Electron Microscopy Of Vitreous Sections)
Available for sale in U.S.A. only
 |
The CEMOVIS 35° knife and the CEMOVIS 25° knife are designed for sectioning frozen hydrated specimens. The 25° angle results in the least possible compression and the best structure preservation.
Please note: best results are achieved at low humidity, when the cryo-ultramicrotome is placed in a glovebox and the sections attached by electrostatic force.
