GA International also known as LabTAG, EDCS-072WH, DYMO Compatible Cryogenic Label for Frozen Surfaces - x 1.04" + 0.375"Features:Quick labeling of frozen vials and tubes (no thawing required)Withstand exposure to solvents, water baths, and condensationCompatible with the 450 series and 4XL DYMO® LabelWritersConvenient to print, no need for ribbons or other ink sourceLabTAG's unique and innovative CryoSTUCK® technology is now accessible for labels compatible with DYMO 450 LabelWriter printers. These solvent-resistant cryogenic labels are specially designed to be directly applied to already frozen surfaces like vials and tubes stored under deep freeze conditions (-80°C/-112°F), which are normally very challenging to label. These labels help preserve the integrity of valuable temperature-sensitive samples and specimens, since there is no need to thaw the containers before attaching them to the frozen vial. They come with a permanent adhesive that will keep the label from falling off or flagging over time under liquid nitrogen's conditions*. Hence, once the labels are applied, the containers/vials can be returned for long-term preservation in liquid nitrogen (-196°C/-321°F) or ultra-low temperature freezers (-80°C). CryoSTUCK labels are ideal for usage in research institutes, clinical laboratories, biobanks, biotechnology companies, and others.In addition to their CryoSTUCK feature, these DYMO-compatible labels display excellent resistance to routinely used laboratory chemicals like detergents, alcohols (100% Ethanol immersion: up to 15 minutes), acetone, xylene (immersion: up to 30 minutes), disinfecting solutions, as well as surface-sanitizing wipes.
