What is a cryostat machine used for?

A cryostat is a microtome machine for cutting tissue at low temperatures (typically around − 15 to − 30 °C) (Figure 55).

What is the principle of cryostat?

The cryostat is the instrument to freeze the tissue and also to cut the frozen tissue for microscopic section. The rapid freezing of the tissue sample converts the water into ice. The firm ice within the tissue acts as embedding media to cut the tissue.
