The Polartherm™ Clamshell Thermal Bag to use:



  • Be sensitive where you keep the vaccine bag. Try to avoid warm areas and direct sunlight and preferably keep in a cool shaded area.
  • Always precondition the vaccines by refrigerating them for a minimum of 48 hours at Circa 2-4°C before transferring to the thermal bag.
  • Coolants should be kept for a minimum of 24 hours in a refrigerator at between 2-4°C before use.
