The new EXPRESS II Microwave Steam Steriliser now has an even larger capacity of 6 AVENT Bottles so that parents can sterilise a whole day's feed in one go. It gives you the same benefits of steam sterilisation using the power of your microwave. Just add 200ml of water, and heat in the microwave to sterilise the contents in only 2 minutes* The specially designed rack makes it easy to place your items inside and can hold up to six 9oz/260ml Bottles or two 9oz/260ml Bottles and two ISIS Breast Pumps. Contents remain sterile for up to 24 hours providing the lid is not removed. This ensures you're ready to feed your baby whatever time of the day or night. The lid is safely secured with two lockable clips. Cooler-touch safety grips on both sides of the steriliser ensure easy handling. The unit fits in most microwaves as it is only 28 cm wide and 16.6 cm high. Its compact design also makes the steriliser ideal for travel.
