SYSTEMS AND METHODS FOR CELL CULTURE DEVICE INTERCONNECTION AND FLUIDIC DEVICE INTERCONNECTION

Systems and methods interconnect cell culture devices and/or fluidic devices by transferring discrete volumes of fluid between devices. A liquid-handling system collects a volume of fluid from at least one source device and deposits the fluid into at least one destination device. In some embodiments, a liquid-handling robot actuates the movement and operation of a fluid collection device in an automated manner to transfer the fluid between the at least one source device and the at least one destination device. In some cases, the at least one source device and the at least one destination device are cell culture devices. The at least one source device and the at least one destination device may be microfluidic or non-microfluidic devices. In some cases, the cell culture devices may be microfluidic cell culture devices. In further cases, the microfluidic cell culture devices may include organ-chips.

The invention relates to a sterile connector for the sterile transfer of a liquid medium, in particular a biological medium, from a liquid container (2) into a fluid chamber (3, 3), wherein the sterile connector (1) has a first coupling device (5) and a second coupling device (6). It is proposed that the first coupling device (5) has a fluid inlet (7) and a fluid outlet (8) and also a first cannula (9), the latter having an end which is directed away from the fluid inlet (7) and forms the fluid outlet (8), that the second coupling device (6) has a fluid passage (10) which, in an initial state of the sterile connector (1), is covered axially by a first septum (11), that the fluid outlet (8), in the initial state of the sterile connector (1), is arranged in a hermetically sealed region of the first coupling device (5) and the surface (11a) of the first septum (11) facing axially away from the fluid passage (10) is arranged in a hermetically sealed region of the second coupling device (6), and that, in a fluidic connection process starting from the initial state of the sterile connector (1), a fluidic connection between the fluid inlet (7) and the fluid passage (10) can be produced by the fact that the end of the first cannula (9) forming the fluid outlet (8) pierces the first septum (11) of the second coupling device (6).

DISPOSABLE DEVICE FOR VENTING A SEALED CONTAINER AND ALIQUOTING THEREFROM

A multi-port disposable device that can both vent a sealed culture vessel and draw a sample therefrom into a collection vessel. The multi-port disposable device has a first port configured to receive the top portion of a culture vessel and attach thereto. The multi-port disposable device has a second port configured to receive a sample collection vessel. The multi-port disposable device has first and second needles. The first needle has a cannula configured to penetrate a septum or cap of the culture vessel. Optionally, the cannula terminates in a layer of foam that carries a microbial agent such that any vapor that is transmitted from the culture vessel through the cannula when venting the sealed culture vessel is absorbed by the foam. Optionally, the ports of the disposable device are configured as sleeves. The sleeve of the first port receives a portion of the culture vessel and the sleeve of the second port receives the collection vessel. The second needle has a cannula that penetrates both the septum or cap of the culture vessel and the septum or cap of the collection vessel, when the culture vessel and the collection vessel are brought into the device, thereby providing for fluid communication between the culture vessel and the collection vessel. The second cannula provides the flow pathway for delivering sample from the culture vessel to the collection vessel.

A suction arm advances in an axial direction of a pipette tip such that an end of the pipette tip comes into contact with a bottom surface of a sample container while the pipette tip attached to a suction arm is tilted with respect to a vertical direction. Next, the suction arm is moved such that the end of the pipette tip scans the bottom surface of the sample container in a horizontal direction toward a predetermined position. Subsequently, at the predetermined position, the suction arm is further tilted by a predetermined angle such that the end of the pipette tip is lifted and a base of the pipette tip is lowered. Thereafter, the suction arm performs a sucking operation such that a sample is sucked through the end of the pipette tip.
