摘要： A locking ring for joining a first and second of a rotor in a centrifugal separator, the first rotor part having a cylindrical end portion, and the second part having an annular flange. A locking ring is arranged to be positioned into a recess and via two radially outer contact surfaces to abut against the end portion and via inner contact surfaces to abut against the flange. The locking ring extends substantially a complete revolution around the rotational axis with two end surfaces turned towards one another and being so formed out of a single piece of resilient material that in an unloaded condition is substantially annular with an outer diameter, is at least as large as the outer radius of the recess, the contact surfaces being are so located that they in every axial section around the rotational axis have a middle point, in which the contact surface have a direction of normalcy, which is the for all contact surfaces. In the direction towards the separation chamber in the interior of the rotor the locking ring forms an acute angle with the rotational axis.

摘要： A centrifuge includes a centrifuge housing and a rotor. The housing defines an inner chamber, and the rotor is provided in the chamber. An indicator is provided on the housing. The indicator is constructed and arranged to indicate rotor movement. A rotor sensor is operatively coupled to the indicator, and the rotor sensor is constructed and arranged to sense rotor movement.

摘要： A centrifuge is provided for the separation and/or treatment of cells in a substantially annular or partially annular separation bag connected by at least one tube to at least one secondary bag. The centrifuge comprises a rotor bowl connected at the upper end of a rotor shaft. The rotor shaft includes a hollow upper portion defining a central compartment for receiving the at least one secondary bag. The rotor bowl includes a separation compartment for receiving the separation bag and an expandable hydraulic chamber located within the separation compartment for selectively squeezing the separation bag within the separation compartment so as to transfer a separated component from the separation bag into a secondary bag in the central compartment. A hydraulic system is connected to the hydraulic chamber by a duct extending through the rotor shaft for pumping a hydraulic liquid to and from the hydraulic chamber.
