Biology:Cryotome

Short description: Cutting device

Cryotome is a microtome device that cold cuts thin blocks of frozen tissue. It is used on tissue that has been removed from the body. The device is designed for rapid microscopic analysis of the tissue. Another type of microtome, called ultracryotome, which is very similar device to crytome, can cut ultrathin blocks if tissue, and that tissue can be observed by transmission electron microscopy. The cutting thickness of ultracryotome is about dozens of nanometers. The ultrastructural properties can be studied without embedding of the tissue, and so the molecular conservation is better.
