The air transportation series is suitable for transporting samples in cryogenic environment (gas phase storage, temperature below -190 °C), which avoids the danger of liquid nitrogen release during transportation, especially for short-time air transportation such as airplanes. There is a liquid nitrogen adsorbent inside, which can absorb and retain liquid nitrogen. Even if the container is dumped, there will be no liquid nitrogen overflow. There is also a special stainless steel mesh screen to separate the storage space and the liquid nitrogen absorbent, which can avoid the liquid nitrogen absorbent material mixed into the cryo-tubes. It is mainly suitable for user needs of laboratory users and a small number of samples for short-term transportation.
