    Abstract: A multichannel pipetting head comprises a plunger actuator comprising at least one groove with an upper border, and a lower border. A plurality of plunger-cylinder units, wherein each plunger-cylinder unit comprises a cylinder and a plunger comprising a plunger head. The plunger head comprises a projecting upper abutment region adjoining the upper border, a projecting lower abutment region adjoining the lower border and laterally offset relative to the projecting upper abutment region, a plurality of guides. Each of the cylinders is coupled to a neck and held on each of the plurality of guides. During lateral movement of the plurality of guides, the plunger head is configured to tilt in the groove and to be held with the upper abutment region abutting the upper border and with the lower abutment region abutting the lower border of the groove due to restoring forces that occur during tilting in the plunger-cylinder units.

    Abstract: A pipette tip comprises a tubular body including an inner circumference and an outer circumference. The tubular body comprises a bottom opening defined at a bottom end of the tubular body and a top opening defined at a top end and configured to clamp onto an attachment of a pipetting device. A seat region is positioned proximate the top opening on the inner circumference and configured to engage an attachment of a pipetting device. At least one groove is defined on the outer circumference. The tubular body is configured to plastically expanded in a radial direction within the at least one groove upon mounting the seat region on the attachment. The attachment comprises a larger diameter than at least part of the seat region to form an interference fit between the attachment and the at least part of the seat region when the pipette tip is clamped onto the attachment.

    Abstract: A lidded vessel assembly comprises a tubular vessel, a lid, and a latching device. The tubular vessel defines a vessel opening and comprises a vessel base, an inner wall, a sealing area and a parking area both defined on the inner wall and both positioned below the vessel opening. The lid comprises a lid base having an inside surface, and a plug projecting from the inside surface of the lid base. The plug is configured to be inserted through the vessel opening to engage the parking area to define a parking position, and configured to be further inserted through the vessel opening out of the parking area to bias against a portion of the sealing area to define a sealing position. The first latching device comprises a first latching element positioned on the inner wall of the vessel, and a second latching element positioned on the outside of the plug.

    Abstract: A centrifuge (10) and a method for preventing the ignition of combustible temperature control media in centrifuges (10) after a crash of the centrifuge rotor are presented. Ignition is prevented by the release of a protective gas in the event of a crash. More precisely, the released protective gas forms a flow that displaces the oxygen, distributes the escaping temperature control medium and fundamentally changes the momentary ratio of the concentration of oxygen to temperature control medium in such a manner that no ignition can take place either inside or outside the centrifuge (10). Thereby, combustible temperature control media can be used without safety concerns for controlling the temperature of centrifuges (10).
