Hiking MH900 1l isothermal stainless steel flask, quick opening cap

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.

Isothermal - tested in the lab

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

- Formalities : 1. Rinse the bottle with boiling water.

2. Fill it completely with water at 95°C. Close it. 3. Leave it in an ambient temperature at 23°C for 24 hours.

4. Measure the drop temperature of the water after 6 hours, 12 hours and 24 hours.

- Performance: Starts at 95°C| after 6 hrs=83°C| after 12 h=75° c| after 24 h=63°C.
