Pens and Labels

We offer a variety of labels and marking pens for lab samples. Please choose from the following or scroll down to view all available labels and pens. Autoclavable Write-On™ Colored Label Tape is custom manufactured from proprietary materials that resist moisture and most solvents. It will adhere to Teflon® fluoropolymer resin covered materials and any clean surface. Samples stay labeled even after steam autoclaving at 121° C (250° F) or freezing down to -73° C (-99° F). Use yellow for chemical reactivity, green for safety labels, blue indicates health hazards, red alerts to flammability; orange indicates a biohazard and white can describe a specific hazard. Tape on a 1" core comes only in white, yellow and green.

Nalgene® Cryogenic marker pens resist fading even at very low temperatures, and Lab Pens are chemically resistant when marked on PolyTape labels.
