Now that you’ve got your RapidCool, you're probably eager to get started but might be wondering exactly how to use it for the first time.

We’ve created a complete guide to help you make the most of your RapidCool, whether at home or out and about, along with tips on sterilising it.

Follow these six simple steps to use your RapidCool:

1. Fill your RapidCool with freshly boiled water, using the measuring markers inside the flask to match the bottle size your baby needs.
2. Add pre-measured formula powder to the freshly boiled water inside the RapidCool.
3. Attach the digital lid and ensure the amber light is displayed, indicating that the feed is still too warm.
4. Shake the RapidCool, turning the flask upside down to ensure the mixture touches the thermostat inside the digital lid.
5. In as little as 2 minutes*, the Nuby logo light will turn green, indicating the feed has cooled and is ready to serve.
6. Pour the cooled feed into a sterilised bottle and test the temperature on your wrist before feeding your baby.

How to use your RapidCool when out

To prepare feeds on the go simply fill the insulated flask with freshly boiled water. This way, you can make a feed safely without needing to find a place to boil water or cut your day out short to return home.

The insulated flask will keep the boiled water at a safe temperature for at least three hours**. You can check the temperature by using the digital lid – if the Nuby logo is red, the water is still hot enough to kill bacteria.

Our handy RapidCool™ Twin Pack Baby Bottle Maker includes a RapidCool™ flask with a digital thermometer lid, an insulated flask for storing water and a milk powder dispenser.
