Cryo diamond knives to produce perfect cryosections

Diamond knives supplied by Agar Scientific are manufactured from high purity, gem quality diamonds providing a sharp, durable edge for sectioning applications in biological and materials sciences. Diatome manufacture a range knives specifically design for cryo applications, these allow:

Thinner cryo sections
Perfect cryosections from ultrathin to semi using 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

Type	Uses
Cryo	For cutting in the cryo-ultramicrotome
Cryo immune	A large diamond platform facilitating pick-up of cryo sections from sucrose infiltrated samples (Tokuyasu)
Cryo 25°	Low angle knife for sectioning frozen hydrated samples (CEMOVIS)
Ultra AFM & cryo AFM	Knives for generating absolutely smooth and flat surfaces of biological and technical samples for the examination in AFM

A re-sharpening and exchange service is also available. Our sales team will be happy to quote for these services.
