The document describes the Maxwell 16 system, a cartridge-based purification system that automates nucleic acid extraction. It can isolate genomic DNA, total RNA, and proteins. Samples that can be used include cultured cells, tissues, blood, bacteria, and food. The system uses magnetic beads to bind, purify, and isolate the targets. It provides high yields of pure nucleic acids and proteins in an automated workflow that is faster and more consistent than manual methods.
