Keep sample identification intact when storage conditions get extreme. These Brady cryogenic polypropylene laboratory labels are built for environments where labels must survive chemical exposure, freezer storage, and repeated handling without losing legibility or adhesion. For labs, the cost of a failed label is not the label itself — it is the sample, the workflow interruption, and the risk to traceability. This label stock is designed for controlled environments that demand durable identification across cryogenic and chemical-resistant applications. The 1/2 in width format supports compact labeling on vials, tubes, and small containers where space is limited and clarity is non-negotiable. Compatibility with Brady BMP21-PLUS, BMP21, ID PAL, LABPAL, and BMP21-LAB printers makes it easier to standardize labeling across lab teams. If your operation depends on accurate sample tracking, this is the kind of consumable that earns its place in the workflow.
