Yes! Ceres Chill is compatible with these major pumps without an adapter:  Medela, Evenflo, Ameda, Ardo
With our adapter available for purchase, Ceres Chill works with Spectra 1 & 2, Bella Baby, Baby Buddha, Cimilre, Motif
All Medela pumps work with all Ceres Chill parts without adapters...except Medela just changed their new Freestyle Flex so that it only fits the Ceres Chill inner chamber and Medela bottles.  You can still use our upper cup as a baby bottle but it will not fit the Flex flange.  This means you can purchase an extra inner chamber or use your own Medela bottles to double pump.
If you have a Lasinoh or Hygeia, please reach out to us so we can make sure we get you a special adapter to accommodate these pumps
Pump into hands-free containers and safely store in the Chiller: Freemie, Elvie, Willow
If you don't see your pump listed here, please reach out to us so that we can confirm whether you need an adapter and to make sure we get you what you need
