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.

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.

SAFETY-Lab safety is always a top priority. Use the Biohazard or Radioactive Tough-Spots to identify tubes or other vessels containing hazardous materials.

Syringe Flag Vaccine Labels

• Identify the vaccine type at a quick glance with the color-coded flag and large text
• The portion of the label that adheres to the syringe is clear, allowing the user to easily identify what it is in the syringe
• A space is provided for the time the vaccine was administered to be handwritten on the label
• Made in the USA

Material:  Mylar with Clear Laminate

Adhesive:  Permanent

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.

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. 

Our patented Cryo-Babies® and Cryo-Tags® withstand both long term cryogenic storage conditions and conventional freezer storage. Cryo labels are chemically inert with a solvent resistant adhesive that will adhere to croygenic vials, microtubes, test tubes, glass vials, beakers and metal racks. Cryo-Babies® and Cryo-Tags® also withstand flash/snap freezing in liquid nitrogen, boiling water baths at 100°C and dry heat up to 150°C.

Our label sheets are specially designed to permanently accept laser printing.
