Dry ice is widely used to keep frozen specimens frozen in transit. Follow your lab's packaging procedure and your carrier's dry ice requirements.
Specimens in sealed secondary containers, inside an insulated shipper, surrounded by dry ice, with a vented outer package.
Specimen and dry ice shipping rules vary by carrier, shipment and mode of transportation. Follow your institution's procedures.
