Centrifuge and centrifuge rotor for suppressing buoyancy

Provided is a centrifuge. 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.

Systems and methods of communicating centrifuge status by LED illuminator of centrifuge housing

A centrifuge includes light sources to provide different illumination states depending on the status of the centrifuge to communicate the status of the centrifuge. The light sources, when activated, project light in the centrifuge chamber and through the centrifuge lid. The light sources are preferably light-emitting diodes. The illumination state is visible up to at least a distance from the centrifuge at which no other visual information on the centrifuge is available. The illumination states allow staff to visually identify the status of a centrifuge from a distance and may reduce turnaround times by enabling staff to identify a completed centrifuge cycle more quickly, reduce staff time wasted checking on the status of a centrifuge, and reduce turnaround time wasted as a result of specimens sitting in a centrifuge after the centrifuge cycle has completed. Methods of communicating the status of a centrifuge are also disclosed.

CENTRIFUGE

Provided is a centrifuge capable of improving user operability. The centrifuge has a rotor chamber and a door for opening and closing the rotor chamber, wherein the centrifuge includes a presence and absence detection part for detecting presence or absence of a rotor, a door locking mechanism capable of switching between a locked state for inhibiting opening of the door and an unlocked state for allowing opening of the door, and a first control part configured to perform an operation of setting the door locking mechanism to be the unlocked state when the rotor is accommodated in the rotor chamber and configured to set the door locking mechanism to be the unlocked state when an unlocking passcode is input.

Centrifuge that obtains an acceleration value and controls rotation

Accurate measurement of acceleration caused by imbalance in the balance of a rotor is realized even in high-speed rotation with an acceleration sensor which has a processing speed required in low-speed rotation and a control unit. A centrifuge according to the present invention includes a rotor, a drive source for rotating the rotor, a rotating shaft for coupling the rotor and the drive source, an acceleration sensor, and a control unit. The acceleration sensor outputs values indicating acceleration in two different directions which are perpendicular to an axial direction of the rotating shaft. The control unit obtains an acceleration corresponding value, which is a value corresponding to acceleration in a direction perpendicular to the axial direction of the rotating shaft, based on values indicating acceleration in the two different directions and stops rotation of the rotor in a case where the acceleration corresponding value satisfies a determination criteria.

Method for sample separation and collection

A centrifuge device and method for use are presented. The centrifuge device includes a housing, a chamber, a channel, and a cover. The housing includes a first port and a vent opening and is designed to rotate about an axis passing through a center of the housing. The chamber is defined within the housing and is coupled to the first port. A first portion of the chamber has a width that tapers between a first width at a first position and a second width at a second position within the chamber, the first width being greater than the second width. The channel is coupled to the second position of the chamber and arranged such that a path exists for gas to travel from the channel to the vent opening. The cover provides a wall that seals the chamber.
