The Nuby RapidCool Flask is a modern solution for making baby formula quickly and safely—especially useful during night feeds or on the day out. Follow the NHS guideline approach: pour freshly boiled water into the flask, add the formula powder, then attach the digital lid. The internal “phase change” cooling system draws heat out rapidly, and the digital lid changes color (to green) when the feed is at a safe temperature. The process typically takes about 2 minutes for a 120 ml feed, though times may vary (2–5 min depending on volume).  

It’s designed to be compact, travel friendly, and easy to clean—no filters or power required. The RapidCool Flask supports feed sizes from 90 ml to 240 ml. Because it works purely via material heat exchange, after a cooldown it needs a reset time (≈ 3 hours) before it’s ready for the next use.
