摘要： In a cell washing centrifuge for washing living cells such as blood cells, control of the remaining amount of a supernatant according to the related art greatly depends on controlling the rotation speed of a motor, and thus a highly accurate motor control part is required to prevent overshooting or the like. In place of the related art, an easy control method is required. In the discharging of a supernatant discharge by a centrifuge having a plurality of test tube holders that can radially swing through centrifugal force, a holding part using an electromagnet that can control the swinging of the test tube holders, and a cleaning liquid distribution element that supplies a cleaning liquid into a test tube, a first decanting operation ({circle around (3)}-1) is performed by rotating a rotor in the order of acceleration, settling, and deceleration in a state in which the agitating angle of the test tube is restricted and discharging the supernatant of the cleaning liquid from the test tube, and a second decanting operation ({circle around (3)}-2) is performed, at a time of a final decanting operation, by accelerating the rotor, releasing restriction on the agitating angle during the acceleration, and then decelerating the rotor.

摘要： A centrifuge device operably configured to simultaneously spin multiple sample tubes at different g-forces during a single centrifugation cycle. The centrifuge device includes a base and a rotatable member disposed within the base and configured as a rotor. The rotatable member includes a plurality of receptacles and a center portion, and wherein each of the receptacles is spaced equally apart from the center portion. The centrifuge also includes a first tube holder selectively inserted within one of the receptacles, wherein the first tube holder includes a first tube therein and a second tube holder selectively inserted within another one of the receptacles, wherein the second tube holder includes a second tube therein. The first tube is operably configured to be spun at a different relative centrifugal force than the second tube.

摘要： A method of evaluating a patient's hematocrit includes collecting a sample of blood in a capillary tube, and placing the capillary tube into a centrifuge having a rotor. The centrifuge has base with a center axis and a manual rotation member. The rotor spins in response to the manual rotation member being pulled by an operator, and the rotor is coupled for rotation to the base. The rotor including a plurality of microfluidic channels. The sample of blood is separated with the centrifuge into a red blood cell portion and a plasma portion in the microfluidic channels. A diagnosis image is provided including a base line indicia, a lower normal line indicia, an upper normal line indicia and a 100 % level line indicia. The capillary tube is placed against the diagnosis image with the bottom end placed adjacent the base line indicia.

摘要： In a centrifuge having a rotor with a rotor body that holds a sample and that is rapidly rotated, an inclined surface that extends upward as it extends radially outward is formed on an upper-side outer peripheral portion of the rotor, in a region that is at a radially outward side and at an upper side of the outer edge of an opening. The inclined surface is a continuous ring-like inclined surface that has the same cross-sectional shape in the circumferential direction and is formed into a straight-line shape or a curved-line shape in cross-section along a rotation central axis. Although winds occur during high-speed rotation of the rotor, the winds are rectified by the inclined surface, and a component force for pressing the rotor body in a downward direction acts thereon.

摘要： A Microtiter plate centrifuge is disclosed. The centrifuge includes a motor assembly, a rotor assembly attached to the motor assembly via a shaft, the rotor assembly including at least two slots, symmetrically positioned, with respect to the shaft and a channel corresponding to each of said slots. The channels extending from the rotor assembly are suitable for holding Microtiter plates in a vertical position. Also included is a bottom plate engaging a brake pad, which when engaged creates sufficient friction to halt rotation of the rotor assembly.
