On one radio episode of Dead Ringers, The Doctor (voiced by Jon Culshaw) 'phoned up Dickinson to ask him how much he could get for a Magnetic Core Extractor that was believed to be owned by the Doctor when he was Jon Pertwee.
The weapon is cooled by a venturi system, which draws cool air down the jacket and acts as a fume extractor.
Once installed, you can open the software, create an account (You must have Broadband Internet connection to play online), and can plug in your DNA extractor gun with a cable on the handle of the gun, which ends in a male USB plug.
