Technical information

How has the insulation of the MH900 isothermal bottle been validated?

We use double stainless-steel wall technology with a vacuum between to block thermal exchange via conduction or convection. To block exchange 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.

How to optimise the performance of your MH900 isothermal flask

This isothermal bottle has been tested in the lab, according to an experienced protocol by our engineers.
