Latest Patents
Markle's latest patents include advancements in magnetic levitation stirring devices and machines for mixing in vessels. The first patent provides a simple method and several machines for simultaneously stirring and aerating thousands of vessels or wells of microplates. This invention utilizes the principle of magnetic stirrers being levitated vertically when passed through a strong horizontal dipole magnetic field. The stirrers, which can take various shapes such as balls, discs, or bars, are attracted to the dipole magnetic field, allowing them to levitate and mix the contents of the vessels vigorously. The design significantly increases aeration by enhancing the air/liquid interface.
The second patent focuses on a magnetic tumble stirring method, which also allows for the simultaneous stirring of thousands of vessels. This method employs a vertical driving magnetic field that causes the stirrers to align and tumble within the vessels. The stirrers' movement is facilitated by their magnetic attraction to the driving magnetic field, resulting in efficient mixing while preventing lateral movement due to vessel walls or friction.
