Abstract: A sample container may include an open end, a closure member, a cap, and an RFID tag. The RFID tag may be positioned near the open end and includes a code uniquely identifying an analytical sample contained in the container structure. A sample handling apparatus may operate with one or more sample containers. The sample handling apparatus may include a robotic assembly for moving a sample probe device and a sample probe supported by a guide of the sample probe device. An RF transceiver antenna may be mounted to the guide for communicating with the RFID tag of the sample container. The sample probe device is moved into proximity with a sample container to read a code stored by an RFID tag attached to the sample container, whereby a sample contained in the sample container can be uniquely identified. The code can be associated with additional information relating to the identified sample.
