The WarmMark Time-Temperature indicators can be used to monitor temperature of products during shipping, storage or processing. Response temperatures available range from 0°F (-18°C) up to 99°F (37°C).

WarmMark® Time-Temperature Indicator, Model 51013-51035, are time temperature indicator labels designed to monitor temperature of products during shipping, storage or processing. Response temperatures available range from 0°F (-18°C) up to 99°F (37°C).

These self-adhesive temperature indicator labels apply directly to product, package, carton or master pack. When activated, these irreversible temperature indicators change color once response temperature is reached or exceeded. Red indicates if exposure was for a brief, moderate or prolonged period of time. With these irreversible temperature indicators you can see at a glance if a temperature abuse has occurred, providing permanent records for quality assurance purposes.

Applications: Shipping, Storage, Distribution of Vaccines, Pharmaceuticals and Blood Products

The WarmMark® Duo Time-Temperature Indicator is a single use label typically applied to vaccines, pharmaceuticals, and blood products for monitoring conditions during storage, shipping and distribution. It has two response temperatures indicating accumulated time above 50°F/10°C, and brief temperature excursions above 93°F/34°C.WarmMark® Duo Time-Temperature Indicator, Model 51036, is a single-use thermal label designed to monitor temperature of blood and blood products, vaccines, and other pharmaceuticals during storage, shipping and distribution. It responds at two temperature thresholds, and is used for products with a known stability curve and with identified expiration characteristics for a specific time/temperature combination.This cost-effective, self-adhesive label can be applied directly to a product and easily fits inside temperature-controlled packaging. When activated, the indicator windows remains white unless the label is exposed to temperatures above 50°F/10°C, then an irreversible red color migrates progressively towards the three windows. If the temperature goes below threshold, the color stops advancing. The first three windows indicate accumulated time above threshold, when colored red they denote exposure up to 3 days, 8 days, and 14 days. The fourth window indicates brief high temperature excursions, and turns red if the temperature goes above 93°F/34°C for at least 30 minutes.

WarmMark® Duo shows at a glance if temperature abuse has occurred and for how long, thus providing visual evidence for making immediate decisions on whether product safety, efficacy and quality have been jeopardized.

Applications: Shipping, Storage, Distribution of Pharmaceuticals, Biologics, Produce, Seafood, and Meat

TempDot® Plus time-temperature indicator labels can be conveniently placed on outer cartons, secondary shipping boxes, or product packaging to continuously track temperature conditions at the pallet level, on single cartons, or individual units. Shipments can be monitored from suppliers and manufacturers, through distribution centers, wholesalers, and during the last mile down to end users. Upon arrival, receivers can use the labels’ visual indication of accumulated temperature abuse as a tool to make immediate decisions regarding whether to reject or accept a shipment, and end users can decide whether to use or discard a product.

TempDot® Plus features a unique serial number, adding traceability to temperature abuse information to help customers meet state and federal regulatory requirements, such as the Food Safety Modernization Act (FSMA), Produce Traceability Initiative (PTI) and the FDA Fish and Fishery Products Hazards and Controls Guidance. The labels are available in various temperature thresholds and run out times. They can be used for many types of temperature sensitive commodities, including food, pharmaceuticals, and biologics.

TempDot® Plus are time- temperature indicator labels for monitoring temperature sensitive products during transport, storage, and handling as they travel through the supply chain. These low-cost single-use temperature indicators will detect ascending temperature excursions that can impact the quality and shelf life of temperature sensitive pharmaceuticals, biologics, and foods such as produce, seafood, and meat. An irreversible color change occurs as each model monitors the cumulative amount of time the label is exposed to temperature above its threshold. The label also features unique graphics, including an activation window which shows the word “ON” to verify when it has been successfully activated.

Applications: Shipping, Storage, Distribution of Vaccines

These labels are a low cost solution to indicate when vaccines have been exposed to high temperatures. Results are easy to interpret so health care workers will know which vials are unsafe to use. This reduces the danger of administering ineffective vaccines to patients and putting them at risk of contracting preventable diseases.

TempDot Plus Duo Label is applied directly to vaccine packaging to monitor temperature during storage, shipping and distribution. It ensures patient safety and eliminates unnecessary discarding of vaccines by verifying efficacy has not been compromised with breaks in the cold chain. Two ascending temperature thresholds provide visual confirmation of exposure above these limits. Window A turns blue after 3 days above 10°C/50°F, window B turns blue after 8 days, window C after 14 days. Window D turns blue after 3 hours above 34°C/93°F.
