Reductor

A Reductor is a special tool used by Adeptus Astartes Apothecaries and Primaris Apothecaries to retrieve the crucial gene-seed of their fallen Battle-Brothers so that new Astartes might be raised from among their Chapter's Aspirants. Retrieval and storage of a fallen Battle-Brother's gene-seed is so critical that Apothecaries carry a special tool for this operation, often included as part of the Narthecium. While a Reductor is not required for Progenoid removal, it significantly reduces the time. This surgical implement fastens under the wrist. It includes a monomolecular saw for penetrating Power Armour and Ossmodula-enhanced rib cages, and a diamantine-tipped extractor drill.

Reductor Pistol
Primaris Apothecaries carry an enhanced version of a Reductor that can also double as a close ranged weapon known as a Reductor Pistol. The Reductor Pistol is similar to the Narthecium's Reductor tool but takes the form of a pistol and is used to both quickly retrieve and store multiple-sets of Astartes gene-seed on the battlefield. The Reductor is designed to punch through Space Marine Power Armour quickly and cleanly; and can do much the same to the skull of a rampaging Ork Warboss if he gets close enough to the Primaris Apothecary.
