1. A modular cryogenic cooler for removably interfacing with an insulated container, said cooler being configured for maintaining an interior of the container at a super-frozen temperature of less than or equal to about −

  • 45 degrees C., said cryogenic cooler comprising;

    a modular connector configured for removable engagement with the container;

    a cryogenic fluid transport module coupled to said modular connector;

    said transport module having a cryogenic fluid supply coupling;

    said supply coupling being couplable to a cryogenic fluid source;

    said transport module being configured to selectively feed cryogenic fluid from the source to the container;

    a controller operationally coupled to said transport module to maintain the interior of the container at the super-frozen temperature;

    said controller including a programmable processor having computer readable program code embodied therein, the computer readable program code including instructions for;

    receiving a temperature reading from a temperature probe;

    comparing said temperature reading to a preselected temperature;

    actuating said transport module to selectively feed cryogenic fluid from said source to said container; and

    wherein said modulator connector comprises a door sized and shaped for sealing engagement with an opening of the container.
