Extraction device assembly

Abstract

An extraction device assembly for extracting a sample from a sample-containing chamber of a nucleic acid amplification cartridge is provided. The assembly has a cartridge interface forming a receptacle configured to at least partially fit the sample-containing chamber therein. The cartridge interface has an aperture configured to at least partially expose the sample-containing chamber, and a collection interface having an aperture configured to at least partially align with the cartridge interface aperture and with the sample-containing chamber positioned at least partially between them. The collection interface aperture is in fluid communication with a collector. The extraction device assembly is operable to fit the sample-containing chamber in the receptacle of the cartridge interface and guide a piercing tool into the cartridge interface aperture to pierce the sample-containing chamber and liberate a sample contained therein for transferral to the collector.
