LabTAG BOC-530C1-0.5BL Blackout FreezerTAG - Deep-Freeze Cover-Up Labels for Thermal-Transfer Barcode Printers 4" x 1.625", Blue 1 Inch Core

Permanent freezer-grade blackout labels, designed to conceal any pre-existing information. These cover-up labels are perfect for re-labeling cryo vials, microtubes and freezer boxes, to be stored in low temperature lab freezers (-80°C/-112°F), as they will completely obscure any existing label. The versatile labels can withstand a wide temperature range, and are also suitable for high temperature applications, as high as 120°C. Compatible with all common thermal-transfer printer brands.
