SECTION 18 DiATOME Diamond Knives For Ultra and Cyro
Extremely smooth sample surfaces. Best possible structure preservation.
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. Available in 35° with a cutting range of 10-100 nm in 2mm and 3 mm sizes.

Trade In
When you need to resharpen your DiATOME Knife we will accept trade in knives from any knife manufacturer and apply the appropriate discount to your new purchase. The size of the knife that is being traded will determine your discount. Please note that there is a limit of one trade in per resharpened knife.
The diamonds that we receive as trade ins are absolutely never used for any of the products that we manufacture or sell.
