ABSTRACT:
An NMR sample spinner comprises first rotational torque means to impart a first rotation to a sample rotor and a second rotational torque means for applying a rotational torque of selected magnitude opposite that applied by said first rotational torque means, whereby positive rotational rate control is more precisely and rapidly realized, sense of rotation is controlled, and undesired rotational torque may be compensated.
