Microwaving is a convenient way to heat up food, but what about your trusty vacuum insulated jar? Let's explore the ins and outs of whether it's safe to put a thermos in the microwave and uncover the do's and don'ts to ensure your flask stays in top-notch condition.

Understanding the Vacuum Flask Construction

A thermos, also known as a vacuum flask, is designed with layers of insulation to keep hot things hot and cold things cold. It typically consists of a double-wall structure with a vacuum in between, preventing heat transfer. This unique construction is essential for maintaining temperature.

The Microwave Conundrum

Microwaving a vacuum flask is not recommended. The reason lies in the vacuum insulation. Microwaves work by creating heat through the vibration of water molecules in food, and without water molecules in the vacuum space, the microwave may damage the thermos or cause it to malfunction.

Potential Risks

Microwaving a vacuum flask can pose several risks, such as damaging the vacuum seal, compromising insulation, and even causing structural issues. It's essential to follow manufacturer guidelines and avoid exposing your vacuum flask to microwave heat. We do not recommend to microwave Energify insulated jars.

Safe Alternatives

If you need to heat the contents of your vacuum flask, transfer them to a microwave-safe container before reheating. This ensures the safety of both your food and your jar, preventing any potential damage.

Caring for Your Vacuum Flask

To maintain the integrity of your jar, follow proper care instructions. Hand wash it with mild soap and warm water, avoiding harsh chemicals and abrasive scrubbers. Regular maintenance will keep your vacuum insulated jar functioning optimally.
