A cryogenic material transfer line has an inner tubular member and a coaxially disposed outer tubular member that together define an annular volume. Within the annular volume is a flow enhancing feature that increases the residence time and path length of a gas flowing within the annulus. The gas flowing inside the annulus thermally interacts with a fluid outside of the transfer line to provide a more consistent gas temperature and flow rate for use in scientific experiments.
