Abstract: A syringe for delivery of liquid to a container has a body with proximal end, a frustoconical distal end, and a cylindrical sidewall extending a longitudinal axis. The syringe includes a nozzle at a distal portion of the syringe, the nozzle having a throughbore providing fluid communication between an interior volume of the syringe and a medical connector configured to be connected to the nozzle. The nozzle includes a plurality of longitudinal ribs formed on an inner surface of the nozzle.
