A freezing microtome is an instrument used in the laboratory to section small delicate materials. Sectioning is done on a platform which is frozen by snowing CO2. The microtome knife is also snowed with CO2.

In this type of microtome, sectioning is done by the microtome knife moving towards the material to be sectioned. For materials that have alcohol, it should first be removed before being sectioned.

Since most biological specimens are too squishy to cut at room temperature, a freezing microtome, also known as a cryostat, freezes the specimen to harden it so it can be sliced without ripping and destroying it.
