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

Tough-Tags are chemically inert polyester labels that strongly adhere to all plastics and other materials. They are temperature resistant from 121°C to -40°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 are thin and the adhesive does not migrate from behind the label even after boiling and autoclaving.

How to set up your laser tags

Our patented Cryogenic labels (Cryo-Babies are the small sizes and Cryo-Tags are the larger), are flexible polyolefin labels that withstand conventional and cryogenic storage conditions (vapor and liquid phase nitrogen storage at -196°C). The labels are chemically inert with a solvent resistant acrylic adhesive that will adhere to all plastics, glass and metal. Cryo-Babies and Cryo-Tags will withstand boiling water baths at 100°C and dry heat up to 150°C without cracking, peeling or degrading.

Cryo-Babies and Cryo-Tags resist most detergents and oils, as well as many organic solvents, caustic agents and other challenges without peeling. They will resist water soaking for at least 24 hours at room temperature and water vapor (100% relative humidity) at 35°C for at least 24 hours.

• TEMPERATURE-RESISTANT - From -196°C to 70°C and also freezable in liquid nitrogen
• TOUGH - Adhere to most plastics, glass and metals without cracking, peeling or degrading; also resistant to scuffing and smearing
• COMPATIBLE - Tubes labeled with Direct Thermal CryoTags easily slide in and out of centrifuge rotors without binding
• SPECIALLY DESIGNED - Labels accept printing from direct thermal printers such as Dymo LabelWriters, both the 400 and 450 styles
• BARCODING - Print popular barcode formats for fast and easy sample identification
• ECONOMICAL - Limit label waste by printing only the quantity required
• NEW FORMAT - Labels are now oriented vertically and are compatible with the new LabelWriter 450
• SAME GREAT PRODUCT - Users of Direct Thermal Tough-Tags will be happy to know weâve expanded the Temp Range of Tough-Tags and made them Cryo-Tags

Cryogenic Labels

Labeling frozen vials, microtubes, microplates, glass tubes, freezer boxes, plastic bags and other containers can be a challenge when storing in temperatures below 20 degrees Celsius.

We offer with 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 80 degree Celsius and as low as 196 degrees Celsius. 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 let the label to remain strong and sticky so that it can be securely attached to stainless steel, aluminum, paint, powder coated metal and iron.

Providing a high quality of the Cryo label is essential for laboratories, researchers, (etc.). It will provide fewer errors, better accuracy, more proficiency, and all of this leads to better results at a better budget.

Removable Tough-Tags are durable labels that cleanly remove from reusable surfaces.

NO RESIDUE- Easily remove from surfaces without leaving adhesive

TRACK SAMPLES- Use labels to follow samples from purification to processing

RESISTANT- Resistant to most laboratory solvents, including short-term resistance to acetone and xylene

USEFUL- Great for beakers, bottles, flasks, glass vials, tubes, tube racks, pipettes

MULTIPLE FORMATS- Available on rolls for handwriting or for direct thermal printing using the Dymo LabelWriter

CryoClear Laser Labels are see through labels that allow the contents of the vials beneath the label to remain visible. They are available in two sizes (for 1.5/2mL tubes and for .5mL tubes)

TEMPTERATURE RESISTANT-Cryo-Clear labels remain fully adhered down to -196°C (liquid and vppor phase liquid nitrogen)

DURABLE-Chemically inert labels resist most organic solvents and caustic agents. Labels adhere to plastics, glass, and metals without cracking, peeling or degrading. Siliconized surfaces should be avoided.

LASER PRINTABLE-Label sheets are specially top-coated to accept laser printing and other markings. Heat resistant stay-flat sheets will not jam in laser printers.

INNOVATIVE-Mad with a flexible, vinyl label material and permanent acrylic adhesive. This unique combination expands and contracts together as temperatures fluctuate resulting in a strong and sustained adhesive bond.
