Closed loop liquid sampler and sampling system

摘要

The invention relates to a sampler mechanism for fluidly interconnecting a ball valve with the interior space of a septum closed container for the taking of closed loop samples of fluid materials. The sampler mechanism includes a needle assembly having a hollow needle and a needle seating collar which is positioned adjacent the ball in the ball valve, a threaded injector end fitting for attaching and securing the needle assembly to the ball valve, and an injector body for fluidly connecting the ball valve to the container and for providing a fluid passageway for fluid communication between the container and a side surface of the injector body.
