Introduction to Glass Lined Vacuum Flask
A glass lined vacuum flask is a type of container designed to keep liquids hot or cold for an extended period. It consists of a glass inner liner, which is often coated to prevent breakage and enhance insulation, and an outer casing, usually made of plastic or stainless – steel. The vacuum between the two layers significantly reduces heat transfer through conduction and convection, while the glass lining provides a non – reactive surface that won’t affect the taste or quality of the stored liquid. These flasks are widely used in households, offices, and outdoor activities due to their excellent thermal insulation properties and durability. Glass Lined Vacuum Flask
