Cryo or cryogenic labels are designed to tolerate extended storage in liquid or vapor phase liquid nitrogen and ultra-low temperature freezers. The face material and adhesive of cryogenic labels are created to remain intact when stored under extremely cold temperatures, and usually for an extended period of time. If labels not engineered for this purpose are used in these conditions, you risk labels falling off the container and ultimately leading to a loss of sample integrity.
How are Cryo Labels Used?
Cryo labels are most commonly used for medical research and in clinical laboratories, fertility clinics, and biobanks. Some items these labels are commonly used on are:
- Cryo vials
- Microtubes
- Cryo boxes
- Tube and vial camps
- Other cryogenic containers
Cryogenic labels are typically available for thermal-transfer, direct thermal, laser, and inkjet printers.
When using cryogenic labels, there are some important factors to consider. There are multiple stages of the cryogenic freezing process. The first stage, sometimes called the deep freeze, can reach temperatures as low as -80°C. The second stage is the vapor phase, which can reach temperatures as low as -120°C. Lastly, is the liquid nitrogen storage stage which can reach temperatures as low as -196°C. It is very important that you know what stage your cryo labels are engineered for.
How to Apply Cryo-Labels
Application is critical when applying cryogenic labels. There are three main ways it can be done: manual, automated and pre-barcoding.
Manual
This application is exactly what it sounds like – labels are applied directly to containers by hand.
Automated
Automation equipment can also be used to apply labels to tubes and vials. Varying degrees of human involvement still exist with this option of application.
Pre-barcoding
Some facilities supply labware with labels already applied. This allows your lab to completely avoid in-house labeling.
This option may not always be practical, however. If your lab utilizes a highly customized internal numbering system or requires information to be printed that isn’t known ahead of time, other options are better suited for you.
