LABELS AND MATERIALS · FREEZER AND CRYO

Freezer and cryo labels

Cryo labels identify samples and products stored frozen or at cryogenic temperatures. The OPAL cryo kits are made of white coated polypropylene with a permanent acrylic-based adhesive and, according to the shop, adhere down to -196 °C. The Cryo B, Cryo D, Cryo DA and Cryo CA kits differ in format, core and roll size.

For freezer and cryo labels, face material and adhesive are decisive, because the label has to stay attached and legible even at very low temperatures. The OPAL cryo kits therefore use coated polypropylene with an acrylic-based adhesive and, according to the shop, adhere down to -196 °C; their print is smudge- and scratch-resistant. They are printed by thermal transfer, and the kits can be ordered with or without ribbon.

The four kits differ in format, labels per roll, core and outer diameter. Cryo B, Cryo DA and Cryo CA run on 76.2 mm cores with outer diameters up to 150 mm or 203 mm, Cryo D on a 25.4 mm core with a maximum of 125 mm. The shop also offers the Zebra 8000T CryoCool, for which Zebra publishes a full data sheet with temperature and chemical data.

Both follow the same principle of coated polypropylene and acrylic adhesive. The Zebra 8000T CryoCool comes with a manufacturer data sheet stating temperature range, minimum application temperature and a chemical list, which helps with validation. The OPAL kits are available as a kit with ribbon and with large rolls on a 76.2 mm core. Without cold exposure, standard labels are sufficient: Go to thermal transfer labels and ribbons

FAQ

Frequently asked questions

Down to which temperature do the cryo labels hold?

For the OPAL cryo kits, the shop states low-temperature adhesion down to -196 °C; no upper limit is given. For the Zebra 8000T CryoCool, Zebra states a service range of -196 °C to 88 °C; the shop also lists dry ice (-80 °C), steam autoclave and gamma radiation.

Can I apply the labels to containers that are already frozen?

The shop does not state a minimum application temperature for the OPAL cryo kits. Zebra states -29 °C for the 8000T CryoCool. Test application in your process with samples before switching.

Which ribbon do I need?

Cryo labels are printed by thermal transfer. Cryo CA can be ordered with a matching resin ribbon, the other kits with or without ribbon. For the Zebra 8000T CryoCool, Zebra recommends the 6200 Standard Resin. According to Zebra, wax ribbons are intended for paper.

Which chemicals can the labels withstand?

Zebra advises testing every application beforehand.

Which kit fits my printer?

Check core and outer diameter: Cryo D has a 25.4 mm core and a maximum outer diameter of 125 mm; Cryo B, DA and CA have 76.2 mm cores and rolls up to 150 mm or 203 mm. The shop pages also assign the kits to printer types with code letters. Tell us your printer model and we will check the combination.

Are other formats available?

Yes. Zebra names tubes, vials and slides as applications for the 8000T CryoCool, and the shop offers several formats. The OPAL label printing shop produces custom formats; describe your containers in the label request form or read more under Labels and consumables.
