Multiport equalization probe
First Claim
1. In a sampling and cleaning apparatus with a pump assembly which includes a pump and a plurality of conduits through which the pump moves material, a cleaning needle for extending into a sealed container through a closure of the container to remove material from the container, said needle including an elongate body having a first and second end, a plurality of lumens in the body, an inlet opening for each lumen, said openings being disposed in a side of the body proximate the first end of the body, and an outlet opening proximate or at the second end of the body for each lumen, said elongate body being closed and sharpened at the first end, said pump assembly conduits being in communication with the lumen outlets, said pump assembly including a conduit for each lumen, each conduit connecting the corresponding lumen to the pump and combining with the corresponding lumen to define a vacuum chamber for removing a predetermined material.
