Introduction


Dear customer, Diamond Knives – Development, manufacturing


and customer service since 1970


Our developments in this period: ultra 45°


ultra 35°


ultra Maxi ultra semi ultra ats histo


cryo


the diamond knife with a hydrophilic cutting edge, allowing high quality ultrathin sections of epoxi resin embedded samples


the low angle diamond knife for reduced compression and better structure preservation


similar to the ultra 35˚ but with a larger boat for alternating sectioning, ultrathin/semithin for placing sections on Si wafers


the fi rst diamond knife for cutting semithin sections for the observation in the optical microscope


the diamond knife for cutting in the cryo-ultramicrotome


Static Line Ionizer for eliminating electrostatic charging cryo immuno


cryo 25 °


ultra AFM and cryo AFM


ultra sonic


ultra sonic Maxi


the knife with a large diamond platform fascilitating pick-up of cryo sections from sucrose infi ltrated samples (Tokuyasu)


the low angle diamond knife for sectioning frozen hydrated samples (CEMOVIS)


the knives for generating absolutely smooth and fl at surfaces of biological and technical samples for the observation in the AFM


the oscillating diamond knife for eliminating compression and allowing best structure preservation


a new wider ultra sonic knife specifically for serial sectioning in biological applications


trim 20, trim 45, for quick, accurate trimming at room and cryo-temperatures trim 90


These developments were possible by the co-operation with you, our valued customers.


We are convinced that also in the future new developments are possible and that our knives may be adapted to the changing requirements.


Make use of our many years experience in perfecting our knives. With a telephone call or an email we can inform you on any details you require. We are looking forward to hear from you soon! Your DiATOME team
