Abstract: 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.
