Liquid nitrogen cell storage system by air phase at -190°C

Abstract

We usually store the cultured cells in the liquid nitrogen system. A vapor phase system with -190°C large container is good to prevent mycoplasma contaminations and for the long period safe storage. We obtained such a large container cell storage system with -190°C recently, whose inner materials were changed to aluminum. Although the system works nicely but we realized that it should be handled quickly when getting out ampoules because of the quick temperature change.
