摘要:
The present invention relates to a computer implemented method for determining a weld integrity test result performed by a system configured to aseptically transferring cells to a container (BR), the method comprising welding (710) a vial to a connector to obtain a fluid-tight seal between the vial (V) and a connector (C), the connector being provided with a pair of conduits each having one end protruding through the connector and into the vial, sealing (720) an opposite end of one of the conduits, generating (730) a fluid pressure different to an ambient fluid pressure at an opposite end of the other conduit, measuring (740) a fluid pressure within at least one of the conduits, determining (750) a fluid pressure change based on the ambient pressure and the measured fluid pressure, determining (760) the weld integrity test result as pass or as fail based on the fluid pressure change.

The invention discloses a distribution plate for supplying crossflow filtration cassettes, which comprises a surface, two opposite end walls, two opposite side walls, a feed channel in fluid communication with a feed inlet port and with a plurality of feed apertures; a retentate channel in fluid communication with a retentate outlet port, and with a plurality of retentate apertures; and a permeate channel in fluid communication with two permeate outlet ports and with a plurality of permeate apertures; wherein the feed channel, the retentate channel and the permeate channel extend in a direction essentially parallel with one or both side walls; wherein the feed apertures are grouped at a first area on the surface, the retentate apertures are grouped at a second area on the surface; wherein the permeate apertures are located at the first and/or the second area; and wherein a plurality of permeate connector channels extend inside the plate from at least one region of the permeate channel, adjacent thepermeate outlet ports and the permeate connector channels provide fluidic communication between the permeate apertures and the permeate channel.
摘要:
A separation or reaction unit (1; 1'; 81; 81'; 101) and a method for aseptically connecting such units. The separation or reaction unit (1; 1'; 81; 81'; 101) comprises at least one fluid inlet (3a, 3b, 5a, 5b; 3a', 3b', 5a', 5b'; 85a, 85b; 103a, 103b) and at least one fluid outlet (3a, 3b, 5a, 5b; 3a', 3b', 5a', 5b'; 85a, 85b; 103a, 103b). At least one of the inlet or outlet is sealed by at least one film (7, 9; 11; 87a, 87b; 107a, 107b) and the contact surface between the film and the separation or reaction unit is aseptic. The films are adapted to be mated with a corresponding film on another separation or reaction unit or on a fluid distribution unit (20; 57; 61) which the separation or reaction unit possibly should be connected with and said mated films are adapted to be pulled out together two and two after mating such that corresponding fluid inlets/outlets on the two connected units are mated aseptically.
