An open‐flow helium cryostat for single‐crystal X‐ray diffraction experiments capable of reaching 14 K has been developed using off‐the‐shelf components. Solid/liquid air build‐up is prevented using the transfer‐line helium back‐flow and a heated nozzle. The system has run for over 30 h with no frost build‐up. The effectiveness of the system has been demonstrated using test data for oxalic acid, terbium vanadate and dysprosium vanadate.
