A device for taking a sample of material from a primary container includes a needle assembly, and intermediate container and a length of tubing. The needle assembly is connectable to a container for receiving a sample of material from the primary container. The intermediate container is connected to the needle assembly through a 3-way connector. The length of tubing is connected to the intermediate container and the needle assembly through the 3-way connector. The length of tubing is connectable to the primary container. With the above construction, material from the primary container is flowable through the length of tubing into the intermediate container and through the needle assembly to obtain a sample of the material into the container for receiving the sample.
