Blackout labels can be affixed to both frozen and ambient temperature containers in order to conceal their existing information. These thermal transfer cryo blackout labels allow cryo vials and tubes to be re-labeled without the need for thawing, cure time, or any other special treatment.

• Temperature range: –196 to 121 °C
• Ideal for permanently obscuring all pre-existing information
• Permanent adhesive ensures no flagging or detachment when stored in liquid nitrogen
• Ideal for labeling already frozen surfaces (as low as –80 °C), without thawing first
• No overlap or wrap-around required for proper adhesion
• Resistant to various chemicals (XAR ribbon recommended)

These cover-up labels are designed to be applied on both frozen and ambient temperature existing labels/surfaces in order to conceal their information. These cryogenic labels are ideal for re-labeling frozen cryo vials and microtubes as well as freezer boxes without the need for thawing, cure time, or any other special treatment. They maintain excellent long-term adhesion for prolonged storage in liquid nitrogen tanks (–196 °C), ultra-low temperature freezers (–80 °C), and dry ice transportation.

They will also resist elevated temperatures and are perfectly suitable for identifying containers destined for standard steam autoclave cycles (121 °C, 16,5psi, 20 minutes) as well as oven dry heat. Blackout labels are printable with most common thermal transfer printers, and the best printout resistance will be generated using XAR-class of solvent-resistant ink ribbons.
