A passive transportable cooling unit for storing vials of allergenic extracts or the like has a vial tray and supporting gel plate filled with a freezable liquid gel, and an insulating carrier having an inner compartment which snugly holds the gel plate and vial tray. The insulated carrier has handle recesses for easy removal of the gel plate and vial tray, and the carrier is expandable for uses other than vial tray storage by means of an extension collar insertable between the carrier box and carrier lid.
