FREEZEmarker®
Are you facing an unnoticed freezing of temperature‑sensitive products such as vaccines, pharmaceuticals, and other cold‑chain goods? Freezing can damage these products without any visible signs, leading to safety risks and product wastage. FREEZEmarker® solves this critical problem by providing an irreversible, easy‑to‑read visual signal whenever a product is exposed to temperatures at or below its set temperature limit. Lisaline Asia is the official supplier of FREEZEmarker® in India.
What is a FREEZEmarker® Freeze Indicator?
FREEZEmarker® is a single‑use freeze indicator label designed to protect temperature‑sensitive products. It provides an easy‑to‑read, irreversible visual signal whenever the product reaches or falls below its response temperature. This temperature indicator label is a self adhesive label that can be directly applied to packaging.
Once exposed to freezing conditions, the indicator undergoes a permanent color or clarity change that cannot be reversed, helping users quickly identify compromised products and avoid administering or using damaged items.
By giving a clear irreversible indication of freeze exposure, FREEZEmarker® helps reduce product wastage and enhance patient and product safety across healthcare, logistics, and manufacturing environments.
How To Read Freeze Indication
- When the temperature remains above the specified level, the green circle with a white checkmark inside remains clearly visible in the indication window. This shows that the product has not been exposed to freezing temperatures.
- When exposed to temperatures at or below the specified level, the green circle and white checkmark turn partially or completely white, opaque, or cloudy, indicating that a temperature excursion has occurred and the indicator’s endpoint has been reached.
- If uncertain whether the endpoint has been reached, gently press the circle with your fingertips to evenly distribute the white particles. Any partial or full white, opaque, or cloudy appearance means the product has been exposed to freezing temperatures and should be treated as potentially compromised.
Uses of FREEZEmarker®
FREEZEmarker® shows if a product has been exposed to freezing temperatures beyond its specified safe limit. It ensures the safety and quality of freeze-sensitive items during storage and transport.
- Monitors freeze exposure.
- Ensures cold chain compliance.
- Detects hidden freeze-thaw events.
- Maintains product quality.
- Ideal for transport and storage.
Advantages of FREEZEmarker® Freeze Indicator
- Instant freeze detection – Clearly indicates if a product has been exposed to sub-zero temperatures.
- Accurate and reliable – Provides an irreversible visual change for easy temperature breach identification.
- Easy to interpret – Simple color change makes it user-friendly for all staff levels.
- Compact and versatile – Can be attached to vials, cartons, or shipping boxes without affecting packaging.

Types of Freeze Indicators: FREEZEmarker®
Each variant of our FREEZEmarker® freeze indicator triggers an irreversible visual change (green checkmark turning white) within 30 minutes if the temperature drops to its set point like 0°C, -1°C, or -4°C. The ±1°C or ±2°C accuracy ensures reliable activation within that small range around the threshold, keeping readings precise.

FAQs- FREEZEmarker®
What are the best freezing indicators in India suitable for cold chain monitoring?
FREEZEmarker® offered by Zebra Technologies are the best freezing indicators in India. They provide a clear, easy-to-read signal that irreversibly changes from a green checkmark to white within 30 minutes of freeze exposure at thresholds like 0°C, -1°C, or -4°C. Lisaline Asia is the official licensed supplier of FREEZEmarker® in India.
What are FREEZEmarker® and how do they work?
FREEZEmarker® are self-adhesive, single-use labels that detect exposure to freezing temperatures in sensitive products such as vaccines or biologics. They start with a visible green circle and white checkmark above the response temperature. Exposure at or below the threshold (e.g., 0°C) causes the green to turn white/opaque irreversibly within 30 minutes. A simple press confirms the permanent alert, enabling quick quality checks throughout the cold chain.
What is the irreversible freeze indicator?
An irreversible freeze indicator like FREEZEmarker® delivers a permanent visual change from green to white or opaque. The freezing temperature indicator does not revert back to green, even if the product later returns to temperatures above the threshold after thawing. This one-way alert reliably confirms freeze exposure, ensuring trustworthy cold chain monitoring for temperature-sensitive goods without false recoveries.
