cryo knives and their applications
• Thinner cryo sections • Perfect cryosections from ultrathin to semi with the same knife • Minimal compression and best structure preservation
• Highest quality diamonds and optimal crystal orientation guarantee perfect ultrathin sections and a durable cutting edge

* Product Codes shown are for new knives. To order a resharpened knife, add “R” to the Product Code that corresponds to your knife. Example: Product Code 30-CD25R = Resharpened cryo 25˚ 1.5mm Knife.
Cryo 35˚ and 45˚ can be exchanged. To order an exchanged knife, add “E” to the Product Code. Example: Product Code 15-CWLE = Exchange of an cryo 35˚ (wet) 1.5mm Knife.
