METHOD AND SYSTEM FOR STORING AND/OR TRANSPORTING TEMPERATURE-SENSITIVE MATERIALS

Methods and systems for maintaining temperature-sensitive materials within a desired temperature range for a period of time. In one embodiment, the system includes an insulated base having a rectangular cavity bounded by a bottom wall and four side walls, the insulated base being positioned within an outer box. A sleeve is snugly but removably positioned in the cavity of the insulated base, the sleeve being generally rectangular but being offset by 45 degrees relative to the insulated base, whereby the sleeve and the insulated base jointly form four discrete generally triangular cavities. Pelletized dry ice may be disposed within each of the cavities. A guide having one end positioned over the sleeve and another end mating with the insulated base may be used to prevent the sleeve from rotating relative to the insulated base. Additional pelletized dry ice may be positioned in a tray mounted on top of the guide.
