ABSTRACT:
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. A cap, including a first key element, is coupled with the mouth. A connector is coupled with the cap. The connector includes a connector head, a probe, and a second key element. The probe extends from the connector head and is insertable through a center of the cap and into the mouth of the container. The probe has a flow passage. The second key element is configured to mate with the first key element. The system also includes a pump coupled with the probe and with the flow passage. The pump pumps fluid through the probe and the flow passage. The system also includes a sensor for sensing when the first and second key elements are mated and for sensing when the first and second key elements are not mated. Finally, the system includes a controller coupled with the sensor and the pump. The controller enables the pump when the sensor senses that the first and second key elements are mated and disables the pump when the sensor senses that the first and second key elements are not mated.
