BRADY FreezerBondz B-490 Polyester Labels for BMP21-PLUS, M210, M211 - 19.05mm x 6.4m, White, Permanent Acrylic, Thermal Transfer, Cryogenic & Lab

In a busy research laboratory, a technician labels cryogenic vials destined for long-term storage in liquid nitrogen. With a BRADY FreezerBondz cartridge loaded into a BMP21-PLUS printer, she prints crisp, durable identifiers that will survive temperatures from -196°C to 110°C and repeated freeze-thaw cycles. This continuous roll of white B-490 polyester labels is engineered for the most demanding identification tasks in biobanks, pharmaceutical labs, and clinical environments.

Why choose it

These labels are built for extreme conditions. The B-490 polyester material resists harsh chemicals, smearing, and abrasion, ensuring that critical sample information remains legible even after years in cryogenic storage. The permanent acrylic adhesive forms a strong bond on vials, tubes, and other laboratory containers, preventing label loss during handling or thawing. With a continuous roll format, you can print labels of any length, reducing waste and increasing efficiency.

Ideal use cases

• Labeling cryogenic vials and tubes stored in liquid nitrogen or ultra-low freezers
• Identifying laboratory samples that undergo repeated freeze-thaw cycles
• Creating durable labels for chemical containers, slides, and microplates
• Tracking specimens in biobanks, pharmaceutical research, and clinical trials
• Marking assets that require resistance to solvents and harsh cleaning agents

Good to know

The cartridge contains one roll of labels and is designed for easy installation in compatible Brady printers. The thermal transfer printing technology delivers sharp, high-contrast text and barcodes that remain readable in low-light or frost-covered conditions. For best results, ensure the label surface is clean and dry before application, and allow the adhesive to set at room temperature when possible. This product is part of the Brady FreezerBondz series, specifically engineered for cryogenic and laboratory identification.
