DiATOME AFM DIAMOND KNIVES, CRYO AND ULTRA
Extremely smooth sample surfaces and best possible structure preservation.
The high quality DiATOME diamond knives are not just perfect for producing ultrathin and semi-thin sections, but also for surface 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 investigations. They produce extremely smooth sample surfaces and guarantee the best possible structure preservation.
Available with a 35° angle and a cutting range of 10-100nm, cutting edge length 2mm and 3mm.
