The Tulip steam bottle warmer is universal, as it is suitable for all bottles and jars (including wide-neck bottles). The adapter ring is used for smaller bottles. The heating time is 3 minutes and 30 seconds for a 240 ml bottle and 4 minutes for a jar. The bottle warmer automatically shuts off with a visual alarm. Thanks to a basket, the heating plate is insulated, allowing silicone bottles to be warmed as well. A measuring cup is also integrated. Suitable from birth. BPA-free.
