A: All ThermoFlask bottles are made of food-grade 18/8 stainless steel and feature a durable powder-coated finish. The lids are made of BPA-Free plastic (PP#5) and feature silicone o-rings to create a leak-proof seal.
Q: How does the thermos flask work?
A: The function of the thermos flask is to prevent the flow of heat to and from the bottle. We know that heat can flow from one place to another by three modes- conduction, convention and radiation. The thermos flask prevents the flow of heat by any of these modes. The flask is made up of glass, which is a bad conductor of heat.
