WarmMark Ascending Time-Temperature Indicator (Single Window)

Heat exposure can irreparably damage temperature-sensitive products like pharmaceuticals, medical samples, chemicals, food, and beverages. Even brief exposure to excessive heat can compromise safety, efficacy, and quality.

WarmMark is a single-use temperature indicator that turns red when a package exceeds its threshold temperature. Unlike standard indicators, it features a time-sensitive countdown, showing whether exposure was brief, moderate, or prolonged—helping you determine if a product remains safe or should be replaced.

Ensure better cold chain visibility and product safety with WarmMark.

Ship-to-Home Pharmaceuticals Case Study: WarmMark

Shipping medications directly from a pharmacy to a patient’s home is a daily standard practice. Maintaining proper temperature during shipment is crucial. If temperature is not monitored and fluctuates, this can make the medication less effective and cause harm to a patient’s health. Adding a WarmMark® temperature indicator ensures the safety of customers, protects your reputation, and reduces time and costs.

Dialysis Case Study: WarmMark®

WarmMark thermal indicators are as easy to use as they are to read. The dialysis center simply adds the WarmMark temperature card to the box containing the blood samples and ships it as usual. When the package arrives, lab technicians have visual confirmation showing whether the samples exceeded safe thermal thresholds and, if so, for how long. Then they know what steps to take to protect the integrity of the results.
