Do not put our stainless steel bottles or vacuum flasks in a microwave. If you need to warm a drink, use a separate container marked for microwave use and follow its instructions.
Use a container intended for microwave heating
A stainless bottle is a drinking container, not a microwave-heating vessel. Follow the bottle’s care guidance and use a separately marked microwave-safe container for reheating.
Keep heating and insulated carrying separate
A vacuum flask is intended to slow cooling during use. Its heat-retention information depends on the model and conditions; it is not a reason to use it as a heating vessel.
What to do instead
- Heat the drink in a container marked for microwave use, following its instructions, then follow the flask’s filling guidance.
- For hot-drink programmes, confirm the flask’s permitted filling temperature and care information with the chosen model.
- Never heat a sealed bottle by any method (microwave, stove or boiling submersion) — trapped steam builds dangerous pressure.
Stainless steel bottles and flasks are not for microwave heating. Confirm the selected model’s permitted use and care instructions; retention information depends on the body, lid and conditions.

Check the material and care instructions for the exact lid and accessory. Do not microwave a component unless its product instructions expressly say it is suitable.
