Ultra Diamond Knife

Ultra Diamond Knife

Highest quality diamonds and optimal crystal orientation guarantee perfect ultrathin sections and a durable edge

Section pick-up is facilitated as the boat is horizontal allowing the water to completely fill the boat all the way round

A hydrophilic surface makes it easy to wet the cutting edge, even with a low water level.

ultra 35° and ultra 45°

ultra 35°

In 1989 J. C. Jésior (Ref. Jésior) demonstrated considerably reduced compression, smoother section surfaces and improved structural preservation thanks to the use of our ultra 35° knives.

In the meantime, a large number of scientists have recognized the advantages of 35° knives, in particular for sectioning Lowicryls and non-homogenous specimens, as well as non-decalcified bone, dental materials, etc.

The ultra 35° knives are perfect for sectioning relatively soft materials research specimens including metals and polymers, as well as hard specimens such as semiconductors, superconducting oxides, catalysts, nano-crystalline ceramics, etc (Refs. Mahon, Glanvill, Swab, Quintana, Maniette, Schubert-Bischoff).

The ultra 35° knife has demonstrated it's usefulness as a standard knife for the majority of applications in both biological and materials research.

The ultra 35° knife (in the triangular holder) with a cutting range of 100nm - 2μm is used for dry sectioning of epoxy or acrylic resin embedded biological samples, which need to be investigated by element analysis (Ref. Edelmann) and SIMS (Ref. Guerquin-Kern). The gliding of the sections on the dry knife surface is facilitated with the use of our Static Line II ionizer.

ultra-semi 35°

Similar to our ultra 35° 3.0 mm with a greater thickness range (50-500nm).

ultra 45°

Acknowledged as the appropriate knife angle for routine sectioning of both biological and material research specimens, it represents a balanced compromise between section quality and durability.

Ultra Jumbo

The Ultra Diamond knife is now available in Jumbo with 35° and 45° angles and in 2.0mm and 3.0mm sizes.

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.
