The  RnaBio Magnetic Tube Stand is developed for manual purification of nucleic acids and other biomolecules using magnetic nanoparticles. This magnetic device allows quick separation of magnetic beads in less than 10 seconds, leading to reduced operation time and isolation of pure DNA or RNA molecules without any contaminants. The ergonomic design of the magnetic stand helps the user to visualize in separation and washing of the magnetic nanoparticles in real-time. It is optimized for manual laboratory work for the isolation of biomolecules using magnetic beads that can hold up to four 1.5 or 2 ml tubes for simultaneous sample preparation. Multiple magnetic stands can be used for more samples.
