Cryogen was a gas used in the field of medicine during the final days of the Galactic Republic. Typically inert until it was mixed with oxygen, Cryogen was used to freeze cells and tissue samples for later use. This substance became important during the Clone Wars, when various cloned organs for clone troopers could be placed in cryogen for storage or transport across the galaxy.
The substance also had offensive purposes, being used with whips by Bartokk assassins. When the weapons struck, they caused cold, near-explosive, chemical reactions capable of freezing metal in a single strike.
Behind the scenesEdit
In the real world, "cryogen" is a generic term for a substance that is liquid at very low temperatures and that acts as a refrigerant.
