It weighs 660 grams and has a capacity of approximately 8 cups, making it ideal for both small gatherings and professional serving situations.

Use the flask in meeting rooms, staff canteens, at catering events or at home around the coffee table, wherever you want to keep beverages at the right temperature for an extended period.

Smart push-button system for easy serving

The flask is fitted with a thoughtfully designed lid with a push-button that enables one-handed operation when serving. The rotatable locking system ensures the contents remain securely sealed when the flask is not in use. This design provides both quick and comfortable serving whilst minimising the risk of spills or drips. The lid is made from durable polypropylene that withstands daily use in busy environments.

Outstanding temperature retention for hours

Inside, the flask is fitted with Helios' silver-coated Q100 quality glass insert with vacuum sealing. This advanced insulation technology keeps hot drinks at around 75°C even after 6 hours, meaning you can enjoy hot coffee or tea long after it was brewed. Equally, the flask keeps cold drinks fresh and chilled for several hours, making it a versatile choice regardless of the season or occasion.
