AFM Diamond Knife
Extremely smooth sample surfaces
Best possible structure preservation
cryo AFM
ultra AFM
The high quality Diatome diamond knives
are not just perfect for producing ultrathin
and semi-thin sections, but also for
surfacing sectioning of all kinds of biological
and industrial specimens for AFM
investigation.
Instead of a section as for TEM, the specimen
surface is investigated using AFM.
In order to achieve the best results for
AFM investigation, only the highest quality
diamond knives should be used.
Diatome ultra AFM and cryo AFM knives
are specially tested to ensure that they
meet the increased quality requirements of
AFM investigation.
They produce extremely smooth sample
surfaces and guarantee the best possible
structure preservation.
