Abstract: Disclosed is a lift type weight measuring centrifuge which is able to measure the weight of a measurement object after spatially isolating the measurement object. The centrifuge includes an upper sensing plate to move upwards, and a weight sensing mechanism provided under the upper sensing plate to sense a weight of the measurement object seated on the upper sensing plate. The centrifuge further includes a lift mechanism to move both the upper sensing plate and the weight sensing mechanism vertically, and a control device to control the operation of the lift mechanism and to measure the weight of the measurement object using a weight sensing signal output from the weight sensing mechanism.

Abstract: An automatic balancing rotor for a centrifuge which compensates for imbalance of a centrifugal force occurring due to a weight difference of samples. The automatic balancing rotor includes a plurality of rotating arms spaced at regular angular intervals, with a plurality of buckets containing the samples supported by the rotating arms. The automatic balancing rotor includes a balance weight provided in each of the rotating arms to be movable in a radial direction, thus compensating for imbalanced centrifugal force applied to the buckets, and a balance weight mover which horizontally moves the balance weight in the radial direction of each of the rotating arms.

Abstract: Provided is an automatic balance adjustable rotor for a centrifuge apparatus which enables to detect a weight unbalance between samples installed to buckets of the rotor, allows the rotor lever to move horizontally by the detection result, and distribute the remaining eccentric unbalance weight by a back lash during the rotation of the rotor. The rotor of the present invention comprises: a rotor lever (100) which ends are configured for supporting buckets in which samples are installed, wherein a block worm gear (104) is installed at the center of the top surface of the rotor lever; a rotor body (110) for supporting and allowing the rotor lever to horizontally move; a lever movement motor (180) installed in the rotor body; and a power transmission means (200) for transmitting a rotational force of the lever movement motor to the block worm gear, allowing the rotor lever to horizontally move.

Abstract: The present invention provides a lift type weight measuring apparatus (400) which is able to measure the weight of a measurement object after spatially isolating the measurement object. The lift type weight measuring apparatus (400) includes an upper sensing plate (410) to move upwards, and weight sensing means provided under the upper sensing plate (410) to sense a weight of the measurement object seated on the upper sensing plate. The lift type weight measuring apparatus (400) further includes lift means to move both the upper sensing plate and the weight sensing means vertically, and control means to control the operation of the lift means and to measure the weight of the measurement object using a weight sensing signal output from the weight sensing means.
