Brady FreezerBondz II Polyester Labels, Black on White, 12.70 x 25.40 mm, Permanent, 180 Labels (M4-131-492)

Laboratory and cryogenic labeling demands extreme durability, and these Brady FreezerBondz II polyester labels deliver exceptional performance even in liquid nitrogen storage at -196°C. The B-492 polyester material with permanent acrylic adhesive stays firmly attached to vials, tubes, and freezer boxes, while the black print on white background ensures crisp legibility.

Advantages

The matte polyester surface resists chemicals, oils, water, abrasion, and smudging, protecting critical sample identification. The labels withstand temperatures from -196°C to 110°C, making them suitable for autoclaving and deep-freeze applications. The permanent adhesive prevents peeling or lifting, even on curved surfaces.
