This multi-colored roll includes 5000 Argos Micryo Dots made from chemically inert polyester with a unique adhesive that is formulated to adhere to laboratory glass and plastic ware. These circular labels will not only withstand conventional freezing (-80°C) but can also be used for most cryogenic storage applications (vapor and liquid phase nitrogen storage at -196°C). No need for separate labeling solutions for your cryo-preservation units and your ultra low freezers. The labels can even be used in incubators. Argos Micryo Labels do not require self lamination to be effective, and the sleeker labels mean your Tube will still fit most storage systems (including cryocanes) without the label sticking or being torn off. Material: chemically inert polyester. Colors: green, blue, purple, red, and yellow. Diameter: 9.5mm. Tube size: 0.5 to 1.5mL.
