CryoSTUCK® – Cryo Labels for Frozen Vials
- Coated with a special adhesive that doesn’t solidify upon contact with a frozen substrate.
- Can be successfully applied to frozen containers at -80°C then stored in liquid nitrogen, dry ice or freezers for further preservation.
- Once applied, they are waterproof and able to withstand multiple freeze-thaw cycles. Can also be used for dry-ice storage and transportation.
The labeling of frozen vials is a significant challenge for many bio-pharma research labs, cell banks, biorepositories and other laboratories involved in the biopreservation of samples in liquid nitrogen and ultra-low temperature freezers. The problem is that the vast majority of cryogenic labels cannot stick to already frozen containers due to the solidification of their adhesive upon contact with a cryogenically frozen surface. Simultaneously, vials containing biological materials cannot be warmed-up due to the temperature sensitivity of their content. In most cases, the re-labeling of these vials has to be done below -70ºC so as not to compromise the viability of the frozen cells.
To help with this task, GA International developed a new and unique cryo label called CryoSTUCK® that can stick to already frozen vials at -80ºC. They are coated with a special adhesive that does not solidify upon contact with a frozen substrate. Therefore, they can be successfully applied to frozen containers and then stored in liquid nitrogen tanks or -80ºC freezers for further preservation, even for decades.
A special feature was implemented in a number of these labels to allow them to completely cover-up frozen vial labels that are now obsolete. These opaque “cover-up” cryo labels are called Blackout CryoSTUCK®. They are designed to completely obscure existing labels and conceal their obsolete information, preventing it from being seen through. They are ideal for re-labeling frozen vials when removal of the existing label is not possible.
For proper functionality, CryoSTUCK® labels must have an overlap of 0.25” or more. Once applied with clear overlap, they are waterproof and able to withstand multiple freeze-thaw cycles. They can also be used for dry-ice storage and transportation.
CryoSTUCK® and Blackout CryoSTUCK® can be printed using standard brands of thermal transfer barcode printers such as SATO, Printronix, CAB, Zebra, Intermec, Datamax O’Neil, Citizen, Cognitive, Brady (selected models) and others. Recommended thermal transfer ribbons: RR-Class resin ribbons. They also accept writing with permanent markers such as our SCIENCE-MARKER™ – Alcohol And Water Resistant Cryogenic Marker
These unique labels can provide an ideal solution to many laboratories involved in long-term biopreservation of samples such as cord blood banks, cell banks, tissue banks, seed banks, sperm banks and other cryogenic storage facilities in biomedical and veterinary fields.
