FAQs

A vacuum flask works by creating a vacuum or empty space between two walls of the flask. This vacuum minimizes heat transfer by condition, convection, and radiation, which helps maintain the temperature of the contents.

Vacuum flasks and thermos bottles are commonly used to keep beverages hot or cold. They are ideal for carrying coffee, tea, soup, water, or other drinks while maintaining their temperature for an extended period.

The duration depends on the quality and design of the flask. High-quality vacuum flasks can keep beverages hot for 12 hours or more and cold for 24 hours or longer.

Yes, many vacuum flasks and thermos bottles are suitable for storing food like soups, stews, or porridge. They can keep food warm for several hours.

It's generally not recommended to put a vacuum flask in the dishwasher or microwave. Handwashing is the safest way to clean them. Microwaving can damage the vacuum insulation.
