Supplied in A4 sheet format for printing in standard desktop laser printers, these laser labels are specifically designed to conceal pre-existing information on frozen containers and vials where thawing the sample is not recommended.

• Temperature range: –196 to 121 °C
• Ideal for permanently obscuring pre-existing information
• Remains intact and readable in ultra-low temperature conditions, as low as –196°C
• Quick template set-up, and printable with office and desktop laser printers (will not jam printers)
• Designed to be applied onto previously frozen (–80 °C) surfaces
• Resistant to spraying with alcohol or rubbing with sanitizing wipes
• Suitable for a wide range of surfaces, including cryo vials, microtubes, as well as cardboard and polycarbonate boxes

Laser printable cryogenic labels specifically designed to be applied onto previously frozen (–80 °C) surfaces, prior to storage in low temperature conditions, including liquid nitrogen (–196 °C). Their unique blackout layer perfectly conceals pre-existing information, ideal as an over-label for frozen containers and vials where no thawing is necessary, thereby preserving the biological integrity of sensitive specimens and samples.

Tested and proven to withstand extreme conditions, they can be applied effortlessly onto frozen surfaces and cryo vials, even those frozen at an ultra-low temperature of –80 °C, then stored directly in liquid nitrogen or inside –80 °C freezers. In addition to their cryogenic resistance, these labels are resistant to heated water bath thawing, remaining attached and legible throughout the thawing process. These labels will also withstand elevated temperatures up to 121 °C, making them ideal for use in autoclaves or heat-based sterilization processes.
