Blackout CryoSTUCK® – Cryogenic Cover-Up Labels for Frozen Surfaces


  • 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
  • Wide temperature range resistance

CryoSTUCK® 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/-321°F), ultra-low temperature freezers (-80°C/-112°F), and dry ice transportation. These blackout CryoSTUCK labels will completely obscure the existing information or even part of the information, such as barcodes or text.

Our permanent cryo blackout labels will also resist elevated temperatures up to +121°C/+249°F and are perfectly suitable for identifying containers destined for standard steam autoclave cycles (+121°C/+250°F, 16.5 psi, 20 minutes) as well as oven dry heat. CryoSTUCK block-out labels are printable with most common thermal-transfer printers, and the best printout resistance will be generated using our XAR-class of solvent-resistant ink ribbons.

When using the recommended XAR ribbon, the printout of these cover-up labels is resistant to various chemicals, including ethanol, isopropanol, acetone and xylene, as well as to wiping and rubbing with alcohol sanitizing wipes.

This super-thin yet durable label will not cause already labeled vials to become too thick for storage racks or centrifuge rotor slots. Near white appearance makes this label appear as the original.

Frequently Asked Questions

Yes, thermal-transfer Blackout CryoSTUCK labels require a thermal-transfer ink ribbon to be printed. These labels require an XAR-class ribbon of the same width or larger compatible with the thermal-transfer printer being used.

No, an overlap is not required for the proper adhesion of these cryogenic labels on ambient or frozen curve and flat surfaces.

Yes, Blackout CryoSTUCK labels have been specially designed for identifying already frozen surfaces. They can be affixed at a minimum temperature of -80°C/-112°F, eliminating the need to thaw valuable samples.

To ensure proper application of these labels, wipe the surface with a clean lint-free disposable wipe (e.g: KimWipe™) prior to affixing the label to remove excess frost. Apply the edge of the label first and press firmly to anchor it, while avoiding excessive contact with the adhesive. Then press the label securely into position along the vials’ entire circumference.

Yes, Blackout CryoSTUCK labels can be used to label samples prior to storing them in low-temperature freezers and liquid nitrogen tanks for prolonged periods.

No, the vials can be stored in liquid nitrogen (-196°C/-321°F) or ultra-low temperature freezers (-80°C/-112°F) immediately following label application, requiring no cure time.

Yes, these Blackout CryoSTUCK labels have a unique opaque design which allows them to conceal pre-existing labels. Perfect for covering-up obsolete information, while still being able to be applied on frozen surfaces.

No, if you want to reinforce an existing label, we offer clear CryoSTUCK labels that can be applied over an existing label while not concealing their printed information. They can thus add an extra layer of protection for your label.

Yes, these thermal-transfer cryogenic labels are resistant to one standard autoclave cycle (+121°C/+249°F, 16psi, 20 minutes).

No, these CryoSTUCK labels have a permanent adhesive that is not made for easy removal.

Please consult our handy sizing guide, where you will find recommendations for the most common vial/tube sizes.

No, these labels are currently available only in sterling white color.

Yes, barcoding or label design software, such as BarTender and ZebraDesigner can be used to create templates that conform to your label’s size. You can then insert design elements within the template for easy printing.

Yes, thermal transfer Blackout CryoSTUCK labels can be preprinted with graphics and logos, as well as variable or serialized information from a database. Learn more about our custom printing options.
