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!

Tough-Tags On A Roll
Tough-Tags are chemically inert polyester labels that strongly adhere to all plastics and other materials. They are temperature resistant from 121°C to â40°C. These labels will withstand autoclaving, boiling water baths, freezer temperatures, organic solvents, caustic agents and other challenges without peeling, cracking or falling off. For best adhesion it is recommended that siliconized surfaces be avoided.
Tough-Tags are pre-cut, peel-off labels which accept any marking instrument and are perfectly sized to fit microcentrifuge tubes and other containers in the laboratory. Tubes with Tough-Tags wrapped around them will still slide easily in and out of rotors without binding because the labels thin and the adhesive does not migrate from behind the label even after boiling and autoclaving.
Label Size: 0.94" x 0.50" (24mm x 13mm)
Ideal Use: 0.5ml tubes
Color: White, Blue, Clear, Green, Orange, Red or Yellow
U of M: 1,000/roll
