The present invention is a system for handling high purity liquid and a method for the same. The system has a container with a mouth. The container is configured to hold liquid. A cap is coupled with the mouth of the container. A connector is coupled with the cap. The connector has a connector head and a probe extending from the connector head. The probe is insertable through the cap and through the mouth into the container. The probe has a flow passage. The system also has a pressurization source that communicates with the container. Pressure delivered from the source acts upon the container forcing liquid out of the container through the flow passage in the probe. There is also a pressurization port communicating with the connector, the cap, and the pressurization source. Pressure from the pressurization source is delivered to the container when the cap and the connector are properly mated. Pressure from the pressurization source is not delivered to the container when the cap and the connector are not mated.
