Glass vacuum flask Ofenbach TERMOS 101323 0.45 L - blue, 0.45 L capacity

Ofenbach TERMOS 101323 is a 0.45 L glass‑lined vacuum flask in blue designed to maintain beverage temperature for everyday use. The flask combines a glass inner container that preserves the original taste of drinks with vacuum insulation that reduces heat transfer. Its compact 0.45 litre capacity and screw‑on lid make it suitable for short trips, office desks and household use where a neutral taste and moderate temperature retention are required.

Advantages

The glass inner vessel prevents metallic or plastic aftertaste, helping to retain the flavour and aroma of coffee, tea or cold drinks. Vacuum insulation reduces heat exchange to keep liquids warmer or colder for longer compared with an uninsulated container. The compact volume and lightweight construction make the flask easy to carry and store in a bag or on a shelf. A screw cap and pourable spout allow straightforward pouring while minimising spills.

Suitable for

• Keeping one to two cups of coffee or tea hot for a few hours
• Storing cold drinks on short trips or picnics
• Use at home or at the office for personal servings
• Transporting beverages where neutral taste retention is preferred

When it may not be suitable

This 0.45 L glass‑lined flask is not intended for long‑term thermal performance comparable to large, high‑performance stainless steel vacuum bottles; temperature will gradually equilibrate over extended periods. The glass inner container is more fragile than metal alternatives and may be unsuitable where the flask is exposed to heavy impacts or rough handling.

Key specifications

• Capacity: 0.45 litres
• Inner material: glass lining
• Insulation: vacuum insulated
• Colour: blue
• Closure: screw cap with pour function
• Intended use: hot and cold beverages

How to use

Preheat or precool the flask by rinsing it with hot or cold water before filling to improve initial temperature retention. Unscrew the lid to fill, pour liquid into the glass inner vessel, then fasten the cap securely. Open the pour spout or slightly loosen the cap to pour. After use, allow the flask to cool before cleaning; hand wash the interior with mild detergent and avoid abrasive cleaners or hard scrubbing to protect the glass lining.

What to consider before purchase

• Glass inner container offers neutral taste but is more fragile than metal
• 0.45 L capacity suits individual servings but is not for long group use
• Hand wash recommended to preserve the glass lining and sealing components
• Not intended for carbonated beverages or for freezing liquids inside

Usage recommendations

For best results, preheat the flask with hot water when storing hot beverages and prechill with cold water for cold drinks. Fill the flask close to the top to minimise air volume and improve temperature retention. Handle with care to avoid impact to the glass inner lining and always check the cap seal before transport.
