Glycol-encased temperature probes are designed for temperature monitoring – particularly for vaccine and pharmaceutical refrigeration and storage. This article details the key functions of glycol temperature probes then explores five excellent examples of thermometers and data loggers that employ this technology.
About Glycol Temperature Probes
These scientific instruments are temperature probes encased in a glycol solution that acts as a buffer to prevent incorrect or unclear temperature readings.
|
The primary purpose of glycol buffers is to protect against sudden and sharp air temperature changes - such as fluctuations due to the opening or closing of refrigerator doors or normal defrost cycles. |
Functionality explained: Imagine you are monitoring the temperature of materials stored in an enclosed environment, such as a fridge. The opening and closing of the fridge doors will readily alter air temperature more quickly than the materials being monitored. Similarly, an open-air temperature probe will react to changes in air temperature more readily than a buffered glycol temperature probe.
|
TLDR (Too Long Didn't Read): A buffered probe will more accurately reflect the temperature of the items stored within a fridge or freezer, particularly vaccine vials, compared to an unbuffered probe. |
The Benefits of Glycol as a Buffer for Temperature Probes
- Glycol mimics the temperature readings of fluids commonly stored in pharmacy and laboratory refrigerators and freezers.
- Glycol’s low freezing point results in more accurate measurements in cold environments.
- Glycol buffering prevents inaccurate measurements and false alarms during rapid temperature fluctuations that pose no risk to stored goods.
- Glycol is non-toxic, making it highly versatile and suitable for use in restricted and controlled laboratories. It is a recommended buffer by the World Health Organization (WHO), Food and Drug Administration (FDA) and the Centers for Disease Control (CDC).

Conclusion
Glycol temperature probes closely mimic the temperature storage properties of vaccines and pharmaceutical products, prevent false alarms caused by rapid air temperature fluctuations within the monitored environment, and meet best practice international health and safety standards. All these attributes make glycol temperature probes the preferred technology for monitoring laboratory and pharmaceutical fridges.
