GA International® Deep-freeze labels are specifically designed for use in ultra-low temperature laboratory freezers (-80°C, -50°C, -20°C) and on dry ice sample storage identification. Unlike typical labels, they can adhere to wet and damp surfaces. Durable, waterproof labels can resist multiple freeze-thaw cycles, and long-term storage. Ideal for labeling small diameter cry tubes, vials, cryobox /freezer boxes, as well as PCR tubes and strips. The freezer-grade labels can be provided in rolls, or sheets, and in an assortment of colors for easy identification and color-coding.
