ABSTRACT:
A method for specimen identification is described, employing marking or printing of a label for placing on a cryogenic storage vial or other container which must withstand contact with the liquid and/or vapor phases of liquid nitrogen at a temperature of approximately -196.degree. C. The marking or printing also resists the ice and moisture which condenses on the container when it is removed from the liquid nitrogen. The method includes the steps of providing a sized portion of a pressure-sensitive adhesive label having a waterproof thermoplastic facestock material with a markable and print-retaining waterproof upper surface and a waterproof adhesive-coated lower surface. The facestock material is capable of being stretched at room temperature at least 10% in the machine direction and at least 10% in the transverse direction without breaking, whereby the facestock and the adhesive can remain united, and also bonded to the container during and after contact with the liquid nitrogen.
