Tough-Tags® are chemically inert labels that strongly adhere to microtubes, test tubes, storage boxes and other microscope slides. They are temperature resistant from 121°C to 40°C and withstand autoclaving, boiling water baths, freezer temperatures, organic solvents and caustic agents. For best adhesion it is recommended that siliconized surfaces be avoided. 

Tough-Tags® are perfect for accurately identifying important samples stored in tubes, microplates or boxes that will be autoclaved or stored in moderate freezer temperatures.

MIDSCI^™ Cryogenic Labels - Sheets

Labeling frozen vials, microtubes, microplates, glass tubes, freezer boxes, plastic bags, and other containers can be a challenge when stored in temperatures below -20ºC.
Providing a high-quality Cryo label is essential for laboratories, researchers, etc. It will provide fewer errors, better accuracy, and more proficiency and all of this leads to better results at a better budget.

We offer a high-quality adhesive that can stick to already-frozen vials and other objects. The adhesive on this type of label will adhere to a surface in wet and/or cold conditions. The adhesive on the label is specifically designed to stick in temperatures below -80ºC and as low as -196ºC. When storing in deep freeze liquid nitrogen or vapor phase liquid nitrogen our Cryo labels will stay in place. MIDSCI^™’s Cryo labels are resistant to smearing without any additional lamination. They also won't become brittle or cracked.

Our cryogenic labels are made of thermoplastic film and coated with a glove-friendly cryogenic adhesive. This special adhesive allows the label to remain strong and sticky so that it can be securely attached to stainless steel, aluminum, paint, powder-coated metal, and iron. 

These labels come on sheets to be printed on by any laser printer for even better efficiency! 

Sheets of microtube labels that can be printed directly from a laser printer, eliminating repetitive writing and saving your valuable time.

Biohazard Tough Spots

Specialty Tough Spots on a Roll are now available for specialty applications, such as identifying hazardous or radioactive samples.

TEMPERATURE RESISTANT- From -196°C to 80°C

SAVE TIME-Preprinted Tough-Spots make labeling and identifying samples quick and easy. Use the numbered tough-spots to identify a series of samples, no handwriting or printing needed.

COLOR CODED-Each color coded Tough-Spot has a distinctly different color to identify similar samples and also includes a white area to clearly write a quick note about it.
