Abstract: A device for freezing adipose tissue comprises a first member and a second member which are mutually coupleable so as to obtain at least one closed configuration; the first member comprising at least one manual grip portion and at least one support portion to which the adipose tissue adheres; the second member comprising at least one housing wherein at least the support portion of the first member is insertable. The second member comprises at least one safety valve that comprises at least one separable portion adapted to detach, partially or completely, from the body of said second member in the case the pressure difference between the inside and the outside exceeds a predetermined value. The second member comprises retention means of the separable portion once it has detached. The detachment of the separable portion creates an opening in the second member, and a gap is defined for the discharge of the gases contained within the housing.

Abstract: Described are a device and a method for rapidly sterilizing liquid nitrogen in a container using ultraviolet radiation irradiated for a predetermined length of time based on the temperature measured by a sensor and on the minimum dose of radiation necessary to kill micro-organisms resistant to liquid nitrogen.
