ProSciTech is an agent for DiATOME. We supply these top quality diamond knives at excellent prices. Why purchase a second-rating knife and hassle with a greater chance of a warranty return, more waiting periods and a lower service life of an inferior knife?

Unique characteristics

DiATOME offers incomparable durability of the diamond edge. DiATOME knives have been known to last for many years without resharpening.
All DiATOME diamonds are of the highest possible quality with a regular crystal structure. The crystal orientation of the diamond permits a final polishing parallel to the cutting edge, which gives a perfect nick free edge.
Uniform sections are easily reproducible.
DiATOME knives are guaranteed for an unlimited number of resharpenings.
When we resharpen our diamond knives, we restore them to their original condition. Your resharpened DiATOME diamond knife will have the same length, the identical cutting edge and carry the same guarantee of quality as the day it first left our factory.
Our diamonds are fastened into a metal shank which is securely screwed into the boat and then sealed. The sealing material is hydrophilic, allowing for easy wetting of the cutting edge, and has no effect on the stability of the knife.
For our cryo knives we use a special epoxy resin for sealing which is chemical and temperature resistant.
Before delivery each knife, new or resharpened, is subjected to extensive testing for its ability to cut accurately without scoring or compression. Only if its performance passes our tests will we ship it to you.
The DiATOME boat is designed in such a manner that the water surface is horizontal when the clearance angle is set. This results in stationary water surface and good reflection.
DiATOME's universal knife boats are designed to fit all brands of ultramicrotomes without the need for an adapter.
The shape of the DiATOME boat offers the advantage of easy pick-up of the floating sections.

Guarantee
Before delivery, each knife, new or resharpened, is subject to extensive testing. Perfect sectioning (in the respective thickness range) over the entire cutting edge is guaranteed. The knives are guaranteed for an unlimited number of resharpenings.

Resharpened diamond knives
Any DiATOME knife can be resharpened an unlimited number of times. Resharpened DiATOME knives undergo the same stringent optical checking and sectioning tests as new knives. A diamond knife resharpened by DiATOME is the same high quality as a new one.
Your resharpened DiATOME knife will have the same length, the identical cutting edge and carry the same guarantee of quality as the day it first left the factory.
Damaged or discoloured boats will be replaced at no charge.

Note for overseas customers: If you send us a diamond knife for resharpening, you must make the Custom's Declaration: No commercial value. Returning for repair. Otherwise, you will be charged the duty payable on the knife.

Resharpened diamond knife with exchange
Rather than having your own knife resharpened, the knife can be exchanged for an already resharpened knife. In the exchange service a type change is also possible (ultra to cryo, 45° to 35°, small knives to large ones, etc). This includes changing the boat to your desired style.

Custom diamond knives and boats
Upon request, we can supply different coloured (black) and shaped boats (Huxley for instance) at no extra cost. Certain applications require special knives and/or tools, outside the standard knives and tools available. For years DiATOME has been manufacturing custom diamond blades, tools and knives for customers, meeting all of their specific needs. There is no charge for this service, only the regular cost of the knife once you have approved it.
