ShareImproved temperature stability in gas-phase nitrogen refrigerators: use of a copper heat shunt.
Author(s) : HUNT C. J., PEGG D. E.
Type of article: Article
Summary
Recent events have demonstrated a significant risk of transmission of infective agents between samples if storage is carried out by immersion in liquid nitrogen. Unfortunately, gas-phase storage does not provide the same uniformity of temperature, nor as low a temperature as immersion, and this may affect stability during long-term preservation. The paper describes a copper heat shunt that is compatible with existing gas-phase inventory systems. Additionally, the heat shunt reduces fluctuations in temperature when the refrigerator is open and maintains a temperature below -160 deg C, even when the refrigerator is open for extended periods.
