Thermos Maestro MR-1630-100, vacuum flask 1 L, stainless steel

Maestro MR-1630-100 is a 1 L vacuum flask with a stainless steel inner chamber and a durable outer construction combining stainless steel, technopolymer and rubber. Designed for daily commuting, travel and outdoor use, the flask offers vacuum thermal insulation and an airtight screw cap to preserve beverage temperature. The product has a compact cylindrical form with a diameter of 8.5 cm and a height of 330 mm, and it includes a 250 ml detachable mug for convenient serving.

Advantages

The vacuum insulation provides reliable temperature retention: up to 12 hours for hot drinks and up to 24 hours for cold beverages. The stainless steel interior resists staining and odour absorption, while the technopolymer and rubber components improve handling and impact resistance. The airtight screw cap prevents leaks during transport, and the flask is engineered for easy cleaning and regular use. At 710 g and 1 L volume, it balances capacity and portability for single-person or small-group use.

How to use

Before first use, rinse the interior with warm water and mild detergent, then rinse thoroughly. To maximise temperature retention, preheat the flask with hot water (or pre-chill with cold water) for several minutes before filling. Tighten the screw cap securely to ensure the airtight seal and avoid leaks. Pour beverages into the main chamber and use the detachable 250 ml mug to serve. After use, disassemble removable parts and clean according to the care instructions to maintain performance.

Usage recommendations

Do not place the flask in a microwave or freezer. Hand wash removable components and avoid abrasive cleaners to preserve the stainless steel finish and sealing surfaces. For best insulation performance, avoid frequent opening and keep the cap closed during transport. Inspect seals periodically and replace if damaged to maintain airtight performance.
