Abstract

Disposable filling machines such as the Acerta® disposable filling machine from Millipore Corporation can use a pump to supply the reservoir with liquid. Typically these pumps have been external to the system so that the user may select the pump of choice or availability. Alternatively, a standard externally mounted pump can be supplied with the system. Another option is to integrate the pump, preferably a peristaltic pump (although other positive displacement pumps such as gear pumps and the like can be used), into the system itself so that the pump would be powered and controlled by the system rather than through some other interface.

Integrated Pump in a Disposable Filling Machine

By Michael Joens, Steve Hunt and Joseph Almasian of Millipore Corporation

                    Disposable filling machines such as the Acerta® disposable filling machine from Millipore Corporation can use a pump to supply the reservoir with liquid.

Typically these pumps have been external to the system so that the user may select the pump of choice or availability. Alternatively, a standard externally mounted pump can be supplied with the system.

Another option is to integrate the pump, preferably a peristaltic pump (although other positive displacement pumps such as gear pumps and the like can be used), into the system itself so that the pump would be powered and controlled by the system rather than through some other interface.

In addition to the convenience, this allows one to control the pump directly, ensures that proper pump size is selected for the system and ensures a compatible and controllable interface between the pump and the system. 

Two pump head options are considered to be acceptable. The first uses a disposable pump head that is driven by a shaft powered and controlled by the system. This allows one to throw away the pump head after use, eliminating cleaning. Alternatively, one can use a non-interchangable pump head permanently attached to and controlled by the system. This allows the pump head to be reused, although cleaning between uses would be required.
