This article describes an automated facility for storing biological samples at -80 degrees C, designed to meet the needs of The UK Biobank. No store of this size has previously used liquid nitrogen as refrigerant, and so it was important to confirm the storage compartments could achieve and maintain uniform conditions with efficient use of the coolant. In addition, the store incorporates a novel system of drawers designed to allow robotic access whilst maintaining storage conditions. Experiments were undertaken to prove the performance of both these factors in maintaining the temperature of stored samples, both in steady-state conditions and during sample access.
