The Nuby RapidCool works by using a special flask that rapidly cools freshly boiled water mixed with formula powder down to the perfect feeding temperature in about 2 minutes. The process is simple: boil fresh water, measure the formula powder, mix them in the RapidCool flask, and wait for the digital display to show a green Nuby logo indicating it’s ready. The flask does not require pre-cooling and cools the formula milk quickly while conforming to NHS guidelines for safe feeding temperature. After use, the flask needs about 3 hours to reset before it can be used again. This rapid cooling is thought to be achieved by the flask's special design, likely involving a phase-change material that absorbs heat to bring the milk to body temperature efficiently without needing cold-water baths or reheating.
How It Works in Detail
- Boil fresh water and pour it into the RapidCool flask.
- Add the measured formula powder.
- Mix well inside the flask.
- The flask cools the mixture from boiling (~100°C) to feeding temperature (~35°C) within 2 minutes.
- The flask displays a green light when the milk is safe and ready for feeding.
- The flask is portable, easy to clean, requires no filters, and can make feeds from 90ml to 240ml.
- After cooling a feed, it requires around 3 hours at room temperature to be ready for the next use, as the cooling mechanism resets itself.
This technology provides busy parents a quick and safe way to prepare formula feeds anywhere without the typical delays and risks of incorrect temperature preparation.
