The Aarke To-Go Bottle for Carbonator 3 is a reusable stainless-steel bottle engineered to be carbonated directly in the compatible Aarke machine. Its 650ml total capacity uses a 450ml marked filling line for carbonation. Double-wall vacuum insulation is designed to keep drinks cold and carbonated for up to 24 hours, so water can be carbonated at home and carried without transferring it into a second bottle.

The bottle is made with more than 90% recycled stainless steel and uses a stainless-steel lid with a food-grade silicone seal. It is dishwasher safe, supporting easier everyday cleaning than Aarke's PET carbonation bottles. Compatibility is model-specific: this version should only be listed against the stated Aarke carbonator family, because Carbonator 3 and Carbonator Pro use different bottle interfaces. It can also be used as an insulated bottle for still drinks when carbonation is not required.

Key Features

Carbonate Directly in Stainless Steel

The bottle fits the Carbonator 3 carbonation system and is filled only to the marked 450ml line before carbonation. There is no need to decant the finished sparkling water into a travel bottle.

Vacuum Insulation

Double stainless-steel walls with vacuum insulation are designed to keep drinks cold and preserve carbonation for up to 24 hours. The bottle is also dishwasher safe.

How It Compares

Compared with Aarke PET bottles, the To-Go Bottle adds vacuum insulation and dishwasher-safe stainless-steel construction. It is heavier than PET and must match the correct carbonator interface.
