GA International CryoSTUCK Cryogenic Labels, 23.9 x 12.7 mm Rectangular + 9.5 mm Round, 750 Labels per Roll, White, for Thermal Transfer Printers

In a busy biobank, a researcher labels cryovials before plunging them into liquid nitrogen. With GA International CryoSTUCK labels, those identifiers stay legible through freeze-thaw cycles, autoclaving, and chemical exposure. This roll provides 750 white labels in two shapes: a 23.9 x 12.7 mm rectangle for tubes and boxes, and a 9.5 mm round dot for vial caps. The permanent cryogenic adhesive bonds firmly to plastics, glass, and cardboard, even at -196°C.

Why choose it

These labels are engineered for extreme conditions. They withstand liquid nitrogen, deep-freezing, autoclaving, boiling water, and harsh solvents like xylene, DMSO, and alcohols. The high-tack adhesive prevents lifting or peeling, ensuring sample integrity. The white surface provides sharp contrast for barcodes and text, and the dual-shape design covers both container sides and caps.

Ideal use cases

• Cryovials and cryotubes stored in liquid nitrogen or -80°C freezers
• Freezer boxes and microplates requiring durable identification
• Plastic bags for specimen transport under cold chain
• Laboratory containers exposed to autoclaving or chemical sterilization

Good to know

For best results, use a thermal transfer printer with a resin ribbon to maximize print durability. The labels are water-resistant and tear-resistant, ensuring they remain intact during handling. Each roll fits a standard 1-inch core, compatible with most benchtop label printers.
