PR1MA™ - CryoTag Rolls for General Use

Labeling containers like frozen vials, microtubes, microplates, glass tubes, freezer boxes, plastic bags, and other containers can be challenging at temperatures below -20ºC. High-quality cryogenic labels are crucial for laboratories to minimize errors, enhance accuracy, and boost cost efficiency.

PR1MA™ Cryogenic Labels feature a premium adhesive designed to stick to already-frozen surfaces, even in wet or cold conditions. This adhesive remains effective at temperatures 80ºC down to -196ºC. Constructed from thermoplastic film and coated with a glove-friendly, cryogenic adhesive, these labels secure strongly to various surfaces including stainless steel, aluminum, paint, powder-coated metal, and iron.

PR1MA™ - CryoTags can be printed or written on and will not bleed, smear, or crack, eliminating the need for additional lamination. They are perfect for distinguishing various specimens after prolonged periods of cold storage.

Conveniently available on rolls, our PR1MA™ - CryoTags are ready for use in your lab!
