Laser labels for deep-freeze and cryogenic use. Cryo-LazrTAG™ labels are ideal for labeling tubes and tops of cryovials, microtubes (i.e. Eppendorf), vacutainer tubes, PCR tubes, cryoboxes, freezer boxes, cell culture plates, microplates, microscope slides, vacutainer tubes, film cans, bottles, flasks, beakers and other various cryogenic and freezer containers. For labeling tops, prior test is recommended due to the versatility of the caps and their surfaces. Designed to withstand long-term storage in liquid and vapor phase nitrogen (-196°C), freezers (-80°C) and dry ice. Waterproof, weatherproof and wear-and-tear proof, Cryo-LazrTAG™ labels are stable at high temperatures up to +120°C and withstand boiling water (+100°C for 2-3 min) and Gamma irradiations (tested up to 50 KGy). They also resist exposure to DMSO and other mild chemicals and detergents, although prior testing is recommended. For the strongest durability against exposure to i) strong organic solvents and chemicals (xylene, toluene, alcohols, formalin) ii) friction, physical wear and tear iii) repetitive cleaning and iv) security concerns (i.e. information loss or tampering), we recommend our DFSL wrap-around cryogenic laser labels.
