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.
The optimal thickness range for cutting with these knives is between 30-150 nm. Whether you requirements are biological or materials related, in EM or LM the DIATOME knives will suit your needs.
Ultra Diamond Knife 45°
Recognized as the appropriate knife angle for routine sectioning of both biological and material research specimens. It is a good compromise between section quality and durability. The 45° Diamond knife is recommended for the sectioning of extremely hard and brittle materials.
This knife is available is sizes ranging from 1.5mm to 4.0mm.
Ultra Diamond Knife 35°
The use of 35° knives leads to reduced compression in soft samples and to less breaking in hard and brittle samples. These knives have proved their capability as a routine knife for many applications.
Resharpened DIATOME knives undergo the same stringent optical checking and sectioning tests as a 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 exact guarantee of quality as the day it first left the factory. Any DIATOME knife can be resharpened an unlimited number of times
This program allows you to exchange any used diamond knife you have for a brand new ultra thin diamond knife and pay a reduced price of a new knife. It does not matter what size you trade in, you may choose any size DIATOME Ultra knife and pay the reduced price of the knife size you choose.
For Room Temperature
Knives are available with a 45° angle
Cutting edge length 4, 6,or 8 mm
Section thickness range 0.2-10 µm
This knife is designed for the sectioning of hard and soft biological and industrial materials, non embedded or embedded in methacrylate or epoxy resins.
The Histo Knife may be used on all ultramicrotomes and microtomes with a retraction of the specimen in the return phase. Only natural diamonds of highest quality are used in the production of the Histo Knives thus guaranteeing the best quality and durability of the cutting edge.
For Cryo Temperatures
Knives are available with a 45°angle ,
Section thickness range 0.2-5 µm ,
Cutting edge length 6 ,8 mm
The histo-cryo knives are delivered in boats (for wet cryo sectioning), and triangular holders (for dry cryo sectioning), made of a special copper/nickel alloy, which guarantees the best heat/cold transmission
Cryotrim 20 and Cryotrim 45
For successful ultramicrotomy biology and materials science, precise trimming is mandatory. The Diatome trimming blades cryotrim 20 and cryotrim 45 will fulfill all your trimming requirements, allowing quick, easy and accurate trimming.
CryoTrim 45 produces pyramidal sides with an inclined angle of 45° and the CryoTrim 20 produces pyramidal side with an inclined angle of 20°
