These are double edged carbon steel blades that are suitable for use with vibrating microtomes. The blades can be broken in half lengthways. The cutting edge has a length of 37mm, and thickness of 127µm.

Sapphire blades for use with vibratomes and microslicers, significantly improving section quality compared with traditional razor blades, particularly in fluorescent labelling, autoradiography, immunohistochemistry and electrophysiology applications. Blades are made from synthetic single crystal sapphires, and are capable of producing distortion free sections down to 10µm thick. Sapphire blades produce cleaner cuts for smoother surface sections, helping to keep surface cells alive and intact and making it easier to follow small labelled elements.
