FormaliTAG™—Formalin and alcohol resistant tags for long-term specimen preservation

These non-adhesive thermal-transfer tags allow permanent and long-term identification of specimens and samples preserved in 10-100% formalin solution and alcohols. Durable and reliable, they are perfect for museum, anatomy and pathology laboratories, and any other facilities involved in preparation, preservation and long-term conservation of biological specimens such as arthropods (insects, arachnids), crustaceans, mollusks, herptiles (amphibians, reptiles), other vertebrates and invertebrates, tissues, organs, and many more.

Resistant to formaldehyde and alcohols, they are intended to be inserted directly into the solution with preserved specimens. Made from chemically inert plastic, they protect the sample information without affecting specimen integrity.

Supplied in continuous roll format, they are compatible with all major brands of thermal-transfer barcode printers including Sato, Datamax, Zebra, and Citizen. The printer must have a cutter option to cut tags to the desired length. To guarantee print resistance to solvents and chemicals, the use of our XAR-class ribbon is essential.

The tags are resistant to standard ethylene oxide gas sterilization, consisting of a 60-minute exposure to 759mg/L of ethylene oxide gas, at 55oC, and 40-80% relative humidity, followed by a two-hour aeration cycle.

When printed with our XAR-class ribbons, formalin resistant tags can also withstand direct contact with many other preservatives and solvents such as:

  • Ethanol (Ethyl Alcohol)
  • Distilled Ethanol (Industrial Alcohol)
  • IPA (Isopropyl Alcohol)
  • Denatured Alcohol
  • DMSO (Dimethyl Sulfoxide)
  • Eosin Y
  • Hematoxylin
