Thermos WAS TERMOSS 5L — stainless-steel vacuum flask, 5 L, Ø16.5 cm, H43 cm

WAS TERMOSS 5L is a stainless-steel vacuum flask with a 5-litre capacity, a 16.5 cm diameter and a height of 43 cm. The flask is engineered to maintain beverage temperature for extended periods through double-wall vacuum insulation. Its compact cylindrical form factor and durable exterior finish make it suitable for stationary use at home, in an office setting or for transport during travel and outdoor activities. The stainless-steel interior resists staining and is simple to clean.

Advantages

The vacuum-insulated construction minimizes heat transfer, helping to keep drinks hot or cold for many hours. The 5-litre capacity supports serving multiple portions without frequent refills, while the relatively small diameter and moderate height improve stability and storage. The stainless-steel surfaces provide corrosion resistance and low maintenance cleaning. The design balances capacity and portability for both indoor and outdoor use.

How to use

Preheat or precool the flask by filling it with hot or cold water for a few minutes and then emptying before adding the desired beverage; this improves temperature retention. Pour liquids directly into the main opening, close the lid securely to maintain the vacuum seal, and use the pour mechanism or spout if provided to serve. Avoid overfilling to prevent spills and ensure safe handling when transporting the filled flask.

Usage recommendations

For best performance, hand wash the interior with mild detergent and avoid abrasive cleaners. Do not place the flask in a dishwasher unless the manufacturer explicitly permits it. Check the lid and seals regularly and tighten before transport; avoid freezing liquids inside the vacuum flask and do not use it to store carbonated beverages.
