HENDI Vacuum Thermos 1 Litre for Hot or Cold Retention

A vacuum thermos keeps liquids at serving temperature without reheating or refrigeration. Between its inner and outer stainless-steel walls a vacuum layer stops heat transfer by conduction and convection. Only radiation remains, and polished metal surfaces reflect most of that back into the flask. The result is hours of stable temperature: hot drinks stay hot, cold drinks stay cold, and the outside of the flask stays cool to the touch.

To use the flask, fill it with the liquid while it is still at the desired temperature. Press the button on the chrome-plated lid to open the pouring spout; the same button seals the flask again when released. The spout directs the flow without drips, and the handle gives a secure grip even with wet hands. There is no switch, no setting and no power supply; the vacuum insulation works continuously once the lid is closed.

The flask is built as a double stainless-steel case with a vacuum between the walls. The lid, button, spout and handle are chrome-plated steel for corrosion resistance and easy cleaning. The 1 litre volume suits single servings of coffee, tea, soup or chilled water in a professional setting where space on the worktop is limited.

Cleaning is done by hand with warm water and mild detergent. The chrome-plated parts should not be scrubbed with abrasive pads to preserve their finish. The vacuum seal is permanent and needs no maintenance, but the lid should be checked for a tight fit after each wash to ensure the insulation remains effective.
