DiversifiedBiotech Tough-Spots Cryogenic Labels - HEAT-SPOTS | Write-On - Made in USA

Fast, reliable manual labeling is essential when preparing samples for deep freeze storage. DiversifiedBiotech Tough-Spots® are circular PVC cryogenic labels uniquely formatted on a roll for quick, easy handwriting. Engineered with a flexible polyolefin material and acrylic adhesive, these labels expand and contract with temperature fluctuations, preventing the peeling and cracking common with inferior stickers. Proudly Made in the USA, Tough-Spots® accept writing from most lab markers and adhere aggressively to virgin polypropylene tubes, glass, and metal.
