Magnetic separation apparatus

, : Magnetic separation apparatus. Official Gazette of the United States Patent & Trademark Office Patents 1228(1), Nov 2

Biological assay systems often involve suspending magnetically attractable particles in a liquid, and later bringing down the particles from suspension and separating the formed pellet from the supernatant liquid. The invention provides magnetic systems for this purpose, shaped to form an annular or part-annular pellet close to the bottom of the vessel. The systems are suitable for automation.
