Pencil, ball-point pen or solvent ink markers remain legible under the most demanding laboratory conditions. Consists of colored paper with rubber resin adhesive that resists moisture and most solvents. The tape will withstand a maximum temperature of 157C (315ºF) for 30 minutes or 80ºC (176ºF) for 24 hours and can be used down to -80ºC (-112ºF). Withstands a steam autoclaving cycle at 121ºC (250ºF) and gamma irradiation between 13.0 and 45.0kGy.
