A cell separation apparatus a container for reception of a cell suspension and a conduit connected to the container for the conveyance of cell suspension out of the container. The conduit extends along a notional conduit path passing centrally through the conduit, the conduit path defining in the conduit an axial direction proceeding along the conduit path, a radial direction orthogonal to the conduit path, and a circumferential direction proceeding around the conduit path. A segment of the conduit constitutes a turbulent flow segment including a flow configuration. The flow configuration includes at least two axial configuration segments located axially behind one another to accelerate a cell suspension.

A laboratory container, in particular a cell culture container, includes a container volume which is surrounded by a container body and which can be accessed from the outside through a container opening of the container body. The container has a fluid line which communicates with the container volume and which comprises a valve arrangement. The fluid line is designed to conduct fluid in order to discharge and/or introduce fluid out of and/or into the container volume. The fluid line can be selectively released in order to conduct a fluid or blocked by the valve arrangement, and the container additionally has a gas balancing opening, through which gas can be introduced into or discharged out of the container volume in counterflow to a possible fluid flow in the fluid line. The gas compensating opening is surrounded by a channel wall, said line channel running from the gas balancing opening into the container volume and opening into said container volume.

A fluid line element for building a fluid line section comprising a plurality of identical fluid line elements, wherein the fluid line element comprises: &#x2014;an element body, &#x2014;a first throughflow opening provided on the element body and a second throughflow opening, different from the first, &#x2014;and a flow channel provided in the element body, which fluidically connects the first and the second throughflow openings for throughflow along a channel path. In a first region of the fluid line element, located closer to the first than to the second throughflow opening, a throughflow body formed separately from the element body is provided, which &#x2014;forms a part of the flow channel, &#x2014;is formed from a material having a lower elasticity modulus than the material of the element body, and &#x2014;on the longitudinal end thereof facing into the interior of the element body, comprises a valve seat formation surrounding the channel path.

Handling device for a laboratory vessel

A pipette device including a metering liquid receptacle designed to be filled, at least in part, with working fluid and which has a pipette opening as a first tapering of cross-section of flow, a pressure change device which is designed to change the pressure of the working fluid in the metering liquid receptacle, and a throttle point in a pipette duct designed to be filled with working fluid as a further tapering of cross-section of flow. The throttle point is arranged fluid-mechanically between the metering liquid receptacle and the pressure change device and is dimensioned in such a way that a ratio of a flow resistance of the pipette opening for dispensed metering liquid to a flow resistance of the throttle point for working fluid, which flows through the throttle point when the metering fluid is dispensed, is less than 0.5.
