The S.T.A.R. Labs biotransfuser is a device that was created by S.T.A.R. Labs. It can transfer the blood of an individual to two or more.


Slade Wilson stole this from the S.T.A.R. Labs' branch in Starling City to transfer the Mirakuru of his blood to his troops. The process of doing so also increases the survivability of Mirakuru subjects, although the life of person the blood being drawn from was at great risk, especially if their blood was being drained into more than one person. Roy was subjected to this and could have been killed if he was disconnected from the machine with it still draining him.
