A valve bridge portion, in which four valves A to D are connected in a bridge shape, is interposed between sample lines to a rotor of a continuous centrifuge. A microcomputer is able to open and close the valves A to D independently and is capable of switching between top feed and bottom feed to the sample line. When sample supply is started, switching between the top feed and the bottom feed is performed multiple times, and in the middle of switching and sending a sample liquid, the microcomputer executes an operation of temporarily increasing a liquid pressure multiple times by temporarily closing an outlet valve (C or D) and then immediately opening the valve. As a result of repeating the operation of switching between the said sample feed directions and temporarily increasing the liquid pressure, air that accumulates inside the rotor can be effectively discharged.

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.

A separator includes a housing that is stationary during operation and designed as a tank having at least two openings. A drum located inside the housing can be rotated about an axis of rotation, the drum having an axis of rotation and at least one opening. A gap is formed at least in sections or continuously between the drum and the housing. The separator also includes a support and drive device having at least two support and/or drive units, which keep the drum suspended inside the housing, supported, and/or set in rotation. One of the support and/or drive units is a first magnetic bearing that at least axially supports the drum and to keep it suspended. At least one other of the support and/or drive units is axially supports the drum.

A separator includes a housing that is stationary during operation and is a tank having at least two openings. A drum is located inside the housing, has a vertical axis of rotation, and a number of openings to the housing corresponding to the openings of the housing. A single multi-part support and drive device with at least one control device and a motor including of a stator, a stator magnet assembly, and a rotor with a rotor magnet assembly, which keep the drum suspended inside the housing, radially and axially supported, and set in rotation. The stator magnet assembly is located outside the housing and the rotor magnet assembly is located inside the housing on the drum so that an air gap is formed between the housing and the drum while the drum is rotating during operation. The axial support and centering of the drum is implemented by controlling the axial position of the rotor magnet assembly using the control device by actuating the motor.
