Introducing the portable (and some might even say perfect) solution for making a formula feed that's not only quick, convenient and hygienic - but also conforms to NHS guidelines. 

Our innovative RapidCool™ Portable Baby Bottle Maker assists in rapidly cooling down a baby's feed in only two minutes*, ensuring you're ready to serve at all times and regardless of location.

How to use:

Making a formula feed in rapid time has never been easier.

  1. Fill your RapidCool™ with freshly boiled water using the measurement markers located inside the flask, add your formula powder and mix well - being sure to turn the flask upside down for at least 10 seconds to allow the mixture to make contact with the thermostat on the inside of the digital lid.
  2. Stand the flask upright and wait for the digital display to show a green Nuby logo.
    Time may vary between 2 - 5 minutes, depending on the size of the feed. 
  3. Dispense contents into a clean, sterile bottle and test the temperature of the formula on the inside of your wrist before giving to your baby.

No cold-water baths to cool a bottle down, no having to reheat a made-up bottle, no worrying about making a feed correctly and no questioning whether this is all too good to be true. Just a safe feed to NHS guidelines, at any time.

Product consists of:

1x RapidCool™ Flask 
1 x Digital Lid (powered by long-life lithium battery)
1 x Small Milk Powder Formula Dispenser
1 x Lid Cleaning Brush

Is this BPA free?

Yes this product is BPA free.

How does RapidCool™work?

The RapidCool™ base uses specialist patented materials within its walls to absorb heat from the boiling water that is used to prepare formula milk, quickly cooling the feed to the perfect temperature. The digital lid has an integrated thermometer that activates when it comes into contact with water.

How do I clean and sterilise the RapidCool™ lid?

The digital lid should be cleaned in warm, soapy water. After cleaning, the lid should be sterilised by UV sterilisation or cold-water sterilisation - for cold-water sterilisation, please follow manufacturer's instructions. The RapidCool™ lid must glow Nuby red when attached to the flask to indicate the water is at the correct temperature. Keep the flask upside down to make sure the water is in contact with the lid for at least 30 seconds. The seal inside the RapidCool lid is also removable to make cleaning after each use super quick and easy. After the lid and seal have been cleaned the lid will be safe to use.


How do I sterilise the RapidCool™ base?

You can sterilise the RapidCool™ base via UV sterilisation, cold water sterilisation or steam sterilisation. Never steam sterilise in a microwave.


Can I mix formula with the boiled water immediately or do I have to wait for the water to cool down to 70°C?

No, you don’t have to wait. Freshly boiled water can and should be used immediately for the safest feed. NHS guidelines state that water should be no less than 70°C, and due to the specialist patented materials within RapidCool™'s walls, freshly boiled water will begin to cool immediately once poured inside - meaning the water will no longer be at boiling temperature but still hot enough to make a feed safely once the formula has been dispensed into the flask. 


Mixing formula with freshly boiled water is the safest way to feed, as it ensures any harmful bacteria are eliminated.

How do I know when the RapidCool™ is ready to use again?


The RapidCool™ works by absorbing heat from hot liquids. After being exposed to heat, it will require a minimum of 3 hours before being ready to use again. The flask should feel cool to the touch.


How does RapidCool™ comply with NHS guidelines?

The NHS guidelines state that when preparing a bottle, you should use freshly boiled water, which has been left no longer than 30 minutes so that it remains at a temperature of at least 70°C. With RapidCool™ you pour freshly boiled water into the base along with your formula, and thanks to its patented technology the bottle will then cool the feed in 2 minutes*. Using freshly boiled water means that any harmful bacteria is killed and the RapidCool™ eliminates the need to run bottles under cold water or use an ice bath to get the feed to the right temperature.

How long can I leave the feed in the flask after preparing it?

We recommend that the feed is used immediately (as soon as the Nuby light turns green and indicates the feed has cooled sufficiently), as per NHS guidelines.


How would this work for night feeds?

The RapidCool™ is quiet and quick, with no noisy machines or plugs needed. There is also the option of keeping hot water to hand in an insulated flask, to save time boiling the kettle in the middle of the night.

How many feeds does it make at a time?

RapidCool™ makes one feed at a time as it requires cleaning and sterilising between uses. We have designed the RapidCool™ so that you have the flexibility of feed sizes between 90ml - 240ml (3oz - 8oz) as your baby grows. There are seven measurement markers located inside the flask between 60ml and 240ml.

How is it powered?

The lid is powered by a long-life lithium battery that does not require charging.


Where should I store the RapidCool?

The RapidCool™ should be stored in a cool dark place, out of direct sunlight.

Can I take my RapidCool™ through airport security?

Security measures may differ between travel providers, so we recommend you check with both your airline, as well as the airport(s) you are travelling through to ensure you can take your RapidCool™ onboard.
