DiATOME® knives are compatible
with all ultramicrotomes
The boat is designed in such a manner that the water is horizontal when the clearance angle is set. This results in a stationary water surface and good reflection. The shape of the boat offers you the advantage of an easy pick-up of the floating sections.
The surfaces of the DiATOME® diamond knives are hydrophilic. This property allows an easy wetting of the cutting edge, even with a very low water level (important for sectioning Lowicryls and other hydrophilic embedding media, as well as for water sensitive samples).
The diamond is high vacuum brazed onto a metal shank which is securely screwed into the boat. The cementing material seals the boat and knife. It is hydrophilic and aids the easy wetting of the cutting edge.
DiATOME® Resharpening & Exchange Service
Resharpened DiATOME® knives undergo the same stringent optical checking and sectioning test as new knives. A diamond knife resharpened by DiATOME® is the same high quality as a new one!
When your knife needs to be resharpened, you may choose to either exchange your knife for a new knife of the same size or you may have your knife resharpened and returned to you.
We guarantee a fast resharpening
service for all our knives including
the oldest knives ever purchased!
DiATOME® Quality Guarantee
Before delivery, each knife, new or resharpened, is subject to extensive testing. We can therefore guarantee perfect sectioning (in the respective thickness range) over the entire cutting edge.
Should a knife not fulfill your expectations, please kindly send it back with a short note of the problem.
