Original Press Release:

Tempilabel° Temperature Monitors Alert Excessive Temperature Exposure of Pharmaceutical/Medical Products

Tempil, an Illinois Tool Works Company, has introduced a temperature monitor which provides highly accurate temperature measurement for heat sensitive materials during storage, shipping and manufacturing. Tempilabelº temperature monitors are self-adhesive, easy to read and available in a variety of shapes and sizes. Their accuracy is guaranteed to be within ± 2% of its rated temperature. They become a permanent record to provide important documentation information.

Pharmaceutical and medical product manufacturers frequently employ the Series 21, 120°F Tempilabel to determine if products have been exposed to temperatures above 120°F. The heat-sensitive indicator changes color, from light gray to black, if its temperature rating is reached. The color change is absolutely irreversible, and a warning message on the label notifies the user that the product must not be used if the color change has occurred.

Tempilabel° is inexpensive and user-friendly. They serve as an excellent protective measure for the pharmaceutical/medical device industries reassuring users of safe temperature levels, and alerting to the problem of excessive temperature exposure should this occur during shipping or storage of heat-sensitive products, drugs and biologicals.

The labels are available in a range of single-temperature ratings from 100° F to 500° F (38° to 260° C), in label size of ½" square (3/16" indicating window) as well as a 5/16" diameter bulls-eye style with 1/8" window. Labels offering several graduated temperature ratings are also available, as are custom labels specially designed to suit the customer's needs.
