An apparatus for infusion equipment comprising a vessel having a tubular bore and a separate actuator pump for the vessel. The apparatus comprises a holder shaped and dimensioned to hold the vessel and a pump attachment to which the holder can be securely fitted. The attachment is shaped and dimensioned to be removably engagable with an actuator pump, to thereby, when the holder is fitted to the pump attachment, removably hold the pump and vessel in mutual fixed relation such that the actuator pump is operably engaged with a piston of the vessel without attaching the vessel to the pump.Embodiments of a case, a kit and a method are also described.
