A connection construction (100) between a centrifuge rotor (102) and a drive shaft (104) of a laboratory centrifuge (200) allows one-handed operation that does not require any additional tools. The connection construction (100) is designed such that the locking mechanism (118, 132, 134) is constantly guaranteed, preventing the jamming or blocking of the locking elements (118, 134).

The invention relates to a centrifuge (10), having a drive shaft (12), a rotor (40) mounted on the drive shaft (12) so as to be detachable axially in a removal direction (66), a quick-action closure (54) integrated in the rotor (40) and the drive shaft (12), which closure can be used to secure the rotor (40) relative to the drive shaft (12) in a removal direction (66), an abutment (50, 52) in the drive shaft (12) which is engaged by a locking member (46) of the rotor (40), at least one blocking element (76), which—when activated—fixes the rotor (40) relative to the drive shaft (12) and which acts between the locking member (46) of the rotor (40) and the abutment (50, 52) of the drive shaft (12), which quick-action closure (54) includes a force-transmitting element (58, 72). The invention is characterized in that said blocking element (76) is actively connected to an actuating element (100, 100a) via the force-transmitting element (58, 72), that unlocking the quick-action closure (54) is effected by moving the actuating element (100, 100a), the force-transmitting element (58, 72) and the blocking element (76) relative to the locking member (46) in a direction in parallel to the drive shaft (12), and that during unlocking, the actuating element (100, 100a) is moved toward the drive shaft (12), and during locking, the force-transmitting element (58, 72) and the blocking element (76) on the one side and the locking member (46) on the other side are relatively moved toward each other.

A centrifuge device, including a base, a rotation platform, and a lock module, is provided. The rotation platform is disposed on the base and adapted to support a rotor of a centrifugal bowl. The rotor is rotatably connected to a stator of the centrifugal bowl. The lock module includes a main body, a lock assembly, and a positioning component. The main body is disposed on the base. The lock assembly is movably connected to the main body and located above the rotation platform. The lock assembly is adapted to be operated to a first state to lock the stator and a second state to be separated from the stator. The positioning component is movably connected to the main body. The positioning component is adapted to move to a first position to position the lock assembly to the first state and a second position to release the lock assembly.

A base unit and a modular centrifugal separator are disclosed. The base unit includes a stationary frame, a rotatable member, and a drive unit. The rotatable member delimits an inner space being configured for receiving at least one part of an exchangeable separation insert therein. The rotatable member is provided with a first opening at a first axial end configured for a first fluid connection of the exchangeable separation insert to extend through the first opening. The rotatable member includes a second opening at a second axial end configured for a second fluid connection of the exchangeable separation insert to extend through the second opening.

A drive device for a solid bowl screw centrifuge includes a motor for rotating a drum of the centrifuge, a transmission which is connected between the motor and the drum, and a cooling device for cooling the transmission during operation when the drum is rotating. The cooling device is an annular body which is fitted on the outside of the transmission and has an air guiding device that conducts air from farther outwards radially inwards onto a surface of the transmission.
