Deep-freeze color dots and rectangles are provided in rolls or sheets, for easy dispensing and peeling. These writable labels are ideal for identifying vial caps, tube tops, as well as the sides of small microcentrifuge tubes, and are provided in a range of colors, or in multi-color packs. Able to withstand extended storage in low-temperature freezers (-20°C/-4°F; -40°C/-40°F; -80°C/-112°F), refrigeration, and dry ice transport, they are also suitable for general use applications, and will resist temperatures up to +110°C.
