Introduction to Glass Lined Vacuum Flask
A glass – lined vacuum flask is a container designed to keep liquids hot or cold for an extended period. It consists of a glass inner liner, which is often coated with a reflective material to reduce heat transfer, and an outer shell, usually made of plastic, stainless steel, or other materials. The vacuum between the inner and outer layers acts as an insulator, minimizing heat loss through conduction and convection. These flasks are widely used in households, offices, and for outdoor activities due to their excellent thermal insulation properties. Glass Lined Vacuum Flask
