■ Ultramicrotome Knives

Cutting range: 30 nm to 250 nm. Edge: 45° included angle, 2 or 3 millimetres minimum usable cutting edge. Holder: Anodised aluminium boat supplied in a box designed for easy transport and protection of the cutting edge.
Polished diamond surfaces are usually hydrophobic, which means that when the water level in the trough is lowered the cutting edge de-wets and efficient cutting becomes difficult. Awindiamond ultramicrotome knives are cut and polished in such a way that the surface of the diamond is hydrophilic, thus ensuring complete wettability of the cutting edge at extremely low water levels. This allows the user to use a lower water level when cutting sensitive materials, such as Lowicryl and LR-white.

■ Cryo Ultramicrotome knives

Cutting range: 30 nm to 250 nm. Edge: 45° included angle, 3 mm minimum usable cutting edge. Holder: High thermal conductivity alloy boat supplied in a box designed for easy transport and protection of the cutting edge.
The cryo-dry knives are especially designed for use in cryo-ultramicrotomes with a working temperature range from - 190° C to ambient. The cryo knife is particularly suitable for the Tokuyasu method.

■ Histology knives

Cutting range: 250 nm to 5 microns. Edge: 45° included angle, 8 mm usable cutting edge (can be used over its full length). Holder: enlarged anodised aluminium boat supplied in a box designed for easy transport and protection of the cutting edge.
Designed for cutting material for light microscopy study. As with all Awindiamond knives for microscopy this product has a hydrophilic surface. A large trough allows large numbers of sections to be parked temporarily in the boat during cutting. The surface is anodised dark blue for better visibility of the sections through the microscope. The histo knife is guaranteed to cut from 0.25 to 5 microns of plastic embedded specimens.
