Area of application

The histo knife is designed for the sectioning of hard and soft biological and material research specimens, non embedded or embedded in acrylic or epoxy resins. (Ref. Reymond).

Our histo knives can be used on all ultramicrotomes as well as on microtomes with a retraction of the specimen arm in the return phase.

 

Our histo cryo knives are delivered with a boat for wet sectioning using a DMSO/water mixture or in triangular holders for dry sectioning. They are made from a special copper-nickel alloy, which guarantees the best possible thermal conduction.

Resharpening service:

A re-sharpened Diatome diamond knife demonstrates the same high quality as a new knife. Even knives purchased in previous years can continue to be resharpened.

For 3D reconstruction it is imperative not to lose a single section (Ref. Blumer).

The large Jumbo boat as well as the adhesive (Pattex compact by Henkel) applied to the side of the sample block increase the distinct advantages of our histo knives.

They allow:

  • Easy production of section ribbons (0.5-2μm)
  • No section loss
  • No folding
  • The same orientation of all sections
  • Easy collection of section ribbons
  • Multiple ribbons on one glass slide
  • Perfect for Immuno-histo-chemistry

Your benefits of working with Diatome

Free customer service

Sectioning tests with biological and material research specimens of all kinds.

We send you the sections along with the surfaced sample, a report on the results obtained and a recommendation of a suitable knife.

Complete discretion when working with proprietary samples.

Re-sharpening and reworking service

A re-sharpened Diatome diamond knife demonstrates the same high quality as a new knife.

Even knives purchased in previous years can continue to be re-sharpened.

All knives can be reworked into another type of knife for no extra charge, e.g. ultra to cryo or 45° to 35°.

Exchange service

Whenever you exchange a knife we offer you a new Diatome.
