How to optimise the performance of your MH900 isothermal flask
We use double stainless-steel wall technology with a vacuum between to block thermal exchange via conduction or convection. To block exchanges by thermal radiation, a fine layer of copper covers the outside of the inner wall.
The fuller the bottle is, the better it is at keeping its contents hot or cold.
Be careful when using hot liquids, the flask is extremely well insulated, liquids will remain hot for a long time.
