Easy to use temperature data logger - logo

Leakproof Glycol Vial

Placing a logger’s probe in a vial of liquid allows you to mimic the temperatures being experienced by liquids (e.g. vaccines) rather than just measuring air temperature. Liquids heat and cool slower than the surrounding air and are less susceptible to quick fluctuations, such as opening the fridge door. This means your temperature log graph will have less severe peaks and troughs.

How the leak-proof vial works

Clever Logger Vial

The probe is pushed through the rubber plug.

The plug forms a leak-proof seal on the vial. It is locked into place by the screw-on cap.

Why put glycol in the vial?

Propylene Glycol is a non-toxic, slightly viscous and colourless liquid. It is ideal for measuring temperatures because it has a freezing point of -59°C.

This means that if the fridge gets below zero, it won’t freeze, unlike some other liquids.

What is NATA?

The National Association of Testing Authorities (NATA) is the recognised national accreditation authority for analytical laboratories and testing service providers in Australia. It is an independent, not-for-profit organisation that provides independent assurance of technical competence. 

NATA accredits organisations to perform testing and inspection activities for their products and services. This gives consumers the assurance they need to make safe, healthy and reliable choices .
