The Difrax screw-off base Wide belongs to the anti-colic S-bottle Wide 200 ml and 310 ml. Together with the anti-colic valve, the base provides a constant air supply, so no vacuum forms and the milk keeps flowing evenly. This is how the S-bottle reduces the risk of tummy cramps, spitting up and burping.
Thanks to the screw-off base, the bottle comes apart completely, is easy to clean and handy to fill with frozen breast milk cubes. The base is supplied in neutral white, as shown in the image.
