Insulated storage/shipping container for maintaining a constant temperature

A container for transporting and storing vessels containing a composition susceptible to physicochemical alteration upon changes in temperature comprising:

• a. a plurality of upstanding walls integral with a base and forming an inner space closed on one end and open on the other;
• b. a first heat sink disposed within said base;
• c. a lid adapted to nest within said open end formed by said upstanding walls;
• d. a second heat sink disposed within said lid;
• e. an insulating insert disposed alongside the inner surfaces of said upstanding walls;
• f. a plate disposed on said insulating insert thereby dividing said container into a top chamber and a bottom chamber, said plate means possessing a center point and an aperture therethrough, and a plurality of apertures in equidistant relation there around, said apertures adapted to removably retain a like number of vessels therethrough and to suspend said vessels within said bottom chamber above said insulated base and spaced away from said insulating insert;
• g. an insulating gas surrounding said vessels and substantially filling the top and bottom chambers;
• and
• h. a temperature indicator disposed within the center aperture for indicating that the inner space has been subjected to temperatures either above or below a predetermined level.
