A cryogenic device for storing biological material containers; said device comprising: a. a sealed cryogenic Dewar vessel accommodating a liquefied gas in an inner space thereof; b. a matrix of receptacles disposed in said inner space and configured for receiving and storing biological material containers; c. means for loading and retrieving said biological material containers; said means comprising a telescopic cane manipulator configured for loading and retrieving said biological material containers within said matrix; said means comprising an airlock isolating said inner space from an outer environment surrounding said sealed cryogenic Dewar vessel; said airlock is configured for passing said biological material containers manipulated by said telescopic cane manipulator therethrough in a sealed manner; wherein said receptacles are carried by a first carousel member rotatable around an axis thereof; said receptacles are arranged into a number of groups distributed over said carousel member; each group of said receptacles has a central point positioned at distance R 1 from said rotation axis of said carousel member; a center of each receptacle within said group is positioned around a central point thereof at distance R 2; said telescopic cane manipulator is rotatable around an axis disposed at R 1 from said rotation axis of said carousel member on an arm of R 2 length such that providing coincidence between said rotation axis of said telescopic cane manipulator with said central point of a receptacle group of interest, a receptacle of interest is loadable or retrievable by said telescopic cane manipulator by rotation thereof around said axis thereof on said R 2 arm. a. a sealed cryogenic Dewar vessel accommodating a liquefied gas in an inner space thereof; b. a matrix of receptacles disposed in said inner space and configured for receiving and storing biological material containers; c. means for loading and retrieving said biological material containers; said means comprising a telescopic cane manipulator configured for loading and retrieving said biological material containers within said matrix; said means comprising an airlock isolating said inner space from an outer environment surrounding said sealed cryogenic Dewar vessel; said airlock is configured for passing said biological material containers manipulated by said telescopic cane manipulator therethrough in a sealed manner; wherein said receptacles are carried by a first carousel member rotatable around an axis thereof; said receptacles are arranged into a number of groups distributed over said carousel member; each group of said receptacles has a central point positioned at distance R 1 from said rotation axis of said carousel member; a center of each receptacle within said group is positioned around a central point thereof at distance R 2; said telescopic cane manipulator is rotatable around an axis disposed at R 1 from said rotation axis of said carousel member on an arm of R 2 length such that providing coincidence between said rotation axis of said telescopic cane manipulator with said central point of a receptacle group of interest, a receptacle of interest is loadable or retrievable by said telescopic cane manipulator by rotation thereof around said axis thereof on said R 2 arm. wherein said receptacles are carried by a first carousel member rotatable around an axis thereof; said receptacles are arranged into a number of groups distributed over said carousel member; each group of said receptacles has a central point positioned at distance R 1 from said rotation axis of said carousel member; a center of each receptacle within said group is positioned around a central point thereof at distance R 2; said telescopic cane manipulator is rotatable around an axis disposed at R 1 from said rotation axis of said carousel member on an arm of R 2 length such that providing coincidence between said rotation axis of said telescopic cane manipulator with said central point of a receptacle group of interest, a receptacle of interest is loadable or retrievable by said telescopic cane manipulator by rotation thereof around said axis thereof on said R 2 arm.
