Abstract
A method for preserving the temperature integrity of cryogenically preserved biological samples is presented, involving initiating a countdown sequence upon removal of a sample from a controlled portable or bulk storage environment, requiring operator action to terminate the countdown on restoration of the sample to a controlled environment. Audible and visual warnings are provided to an operator prior to attainment of a critical temperature, beyond which damage may accrue to the sample. A portable device facilitating execution of the method is described.
