Indoctrination serum hypodermic

An indoctrination serum hypodermic (PROSE: Dalek Combat Training Manual) was used by Kiston on behalf of Davros during the Duplicate Incident. Aboard a Prison Station, two Daleks sent by the Supreme Dalek released their docking clamps, ostensibly so that Kiston could extract samples of Dalek tissue for Davros' research into the Movellan virus. In reality, the device used by Kiston, once administered to the mutant Daleks, conditioned them to obey Davros. (TV: Resurrection of the Daleks)
