  • Magnetic separator with magnetic compensated release mechanism for separating biological material
    Patent number: 5779892
    Abstract: A magnetic separator device is provided for separating biological materials from carrier fluids using the technique of high gradient magnetic separation. A release compensator reduces the amount of force that an operator needs to apply in order to remove a separation column from the magnetic field of the separator device. The release compensator may be a mechanical compensator, but is preferably a magnetic compensator. The magnetic separator device also preferably includes a mount for mounting the device to a wall. The mount is preferably a pair of additional magnets.
