The invention relates to a centrifuge (), having a drive shaft (), a rotor (), which is mounted on the drive shaft () and is axially removable in a removal direction (), a quick closure (), which operates between the rotor () and the drive shaft () and by means of which the rotor () can be fixed relative to the drive shaft () in the removal direction (), a thrust bearing () connected to the drive shaft (), a locking bearing () connected to the rotor (), at least one blocking element (), which, when activated, fixes the rotor () relative to the drive shaft () and operates between the locking bearing () of the rotor () and the thrust bearing () of the drive shaft (). The pivot axis () is aligned perpendicular to a straight line parallel to the drive shaft () and the blocking element () has a cardan shaft (), which is rotatable about the pivot axis (), and is connected to a bearing () via the cardan shaft ().

Centrifuge

A centrifuge (), having a drive shaft (), a rotor () mounted on the drive shaft () so as to be detachable axially in a removal direction (), a quick-action closure () integrated in the rotor () and the drive shaft (), which closure can be used to secure the rotor () relative to the drive shaft () in a removal direction (), an abutment () in the drive shaft () which is engaged by a locking member () of the rotor (), at least one blocking element (), which&#x2014;when activated&#x2014;fixes the rotor () relative to the drive shaft () and which acts between the locking member () of the rotor () and the abutment () of the drive shaft (), which quick-action closure () includes a force-transmitting element (). The blocking element () is actively connected to an actuating element () via the force-transmitting element (), that unlocking the quick-action closure () is effected by moving the actuating element (), the force-transmitting element () and the blocking element () relative to the locking member () in a direction in parallel to the drive shaft (), and that during unlocking, the actuating element () is moved toward the drive shaft (), and during locking, the force-transmitting element () and the blocking element () on the one side and the locking member () on the other side are relatively moved toward each other.

Centrifuge with quick action closure securing the rotor to the drive shaft

A rotorof a centrifugehaving a rotor axis R, a receiving spacefor samples to be centrifuged, a lidwhich limits the receiving spaceat the top, which is concentrically mounted relative to the rotor and which has, on its side remote from the receiving space, a handlefor carrying the rotor and the lid, and a locking mechanism of lidand rotor, which mechanism is mounted in a supportin the lid, said locking mechanismcomprising a locking elementadapted to be movable between a locking position and an unlocking position and which has an actuating memberand a latching element, with the actuating memberand the latching elementbeing axially spaced from each other relative to the rotor axis R. The invention is characterized in that the locking elementis formed by a tilt lever which has the actuating membermounted on its upper end and the latching elementmounted on its lower end, with its pivot axis being aligned perpendicular to the rotor axis R.

Centrifuge rotor with lid locking mechanism

A rotorof a centrifuge, having a receiving chamberfor samples to be centrifuged, a concentrically mounted seatwhich is associated with a supportof a drive shaftof said centrifuge, a lidwhich limits the receiving chamberat the top, which is mounted concentrically relative to the rotor and which has, on its side remote from the receiving chamber, a handlefor carrying the rotor and the lid, and a locking mechanismof lidand rotor, which locking mechanismcomprises a locking elementwhich can be moved between a locking position and an unlocking position thereof. In accordance with the invention, part of the handleis adapted to be movable and is operatively connected to a retaining element, which retaining elementcan be moved, by the handle, between a first position which prevents actuation of the locking element, and a second position which releases the locking element
