Autoclave tape used in many laboratories may contain levels of lead that exceed the hazardous waste limit for trash disposal.
Most lead-containing autoclave tape has stripes running across at an angle (/ / / / / /). The stripes appear light beige under normal conditions and darken in the autoclave when exposed to sufficiently high heat and pressure (see image at right). In some brands of tape, the color changing compound in the angled stripes may contain lead.
Tape that displays the word "Autoclaved" instead of angled stripes is most likely lead-free. The best way to determine if your autoclave tape contains lead is to check the Safety Data Sheet (SDS).
