A shaking and/or mixing device comprises: a drive (7a) having a drive shaft (7), an eccentric unit (4) driven by the drive shaft (7) and having an eccentric hub (14), and a holder (20) for receiving at least one sample to be treated by the shaking and/or mixing device (1). The eccentric hub (14) and the holder (20) are connectable to one another by means of a releasable connection in order to transmit a movement of the eccentric hub (14) onto the holder (20) and the releasable connection is provided as an extension of the drive shaft (7).

The disclosure provides example rinse station apparatus, cartridges, and methods for flow cytometry. The rinse station apparatus includes: (a) a cartridge docking station having a base with a recessed receptacle for a cartridge, a vertical support coupled to the base's first end and a top support coupled to the vertical support and cantilevered over the base, the top support has an opening that aligns with the cartridge's opening, (b) a locking arm coupled to the base's second end, the locking arm's free end has a ridge to cooperate with a detent coupled to the cartridge's rear wall to retain the cartridge in place, (c) a spring coupled to the vertical support's front face to apply force to the cartridge's front wall to bias the cartridge toward the locking arm, and (d) a load cell coupled to the base of the cartridge docking station, the load cell measure's the cartridge's weight.

A laboratory instrument for mixing a medium in an object carrier, wherein the laboratory instrument includes a support body, a main component for receiving the object carrier which is disposed on the support body and is movable with respect to the support body for mixing, and a mixing drive mechanism disposed on the support body, with a drive device, a first eccentric and a second eccentric, which can be driven by means of the drive device and which are configured in order to transmit a driving force produced by the drive device to the main component in order to mix the medium in the object carrier, wherein the first eccentric and the second eccentric are disposed on a peripheral edge of the support body and outside a central region of the support body.

A sealed airflow system suitable for use with a sample shaker assembly. The sealed airflow system includes at least one component which accommodates movement of the sample shaker assembly while maintaining an air tight assembly between components of the sealed air flow system. A compliant sliding seal compensates for movement of the sample shaker assembly with regard to an air intake side of the sealed airflow control system. Additionally, a flexible conduit provides an air tight passage between an outlet of the sealed airflow control system and an exhaust port. The flexible conduit compensates for movement of the sample shaker assembly in a manner that does not permit unwanted airflow into or out of sealed airflow control system.

A laboratory instrument for fixing an object carrier, the instrument including a main component for receiving an object carrier, a positioning fixture for application to a first edge region of the object carrier, a second positioning fixture for application to a second edge region of the object carrier, a fixing mechanism for fixing the object carrier on the main component between the first positioning fixture and the second positioning fixture by moving at least the first positioning fixture, and an actuating device for actuating the fixing mechanism for transposing at least the first positioning fixture between an operational state and an operational state which releases the object carrier, wherein the fixing mechanism includes at least one guide body which can be guided in at least one guide recess.
