The patented Ceres Chill Chiller is rigorously lab-tested to provide longer and more reliable chilling than any other on-the-go breastmilk storage solution. Our Science page has all the details and even testing reports and charts for those who love to dig into data!

In support of busy families, we offer a Warmer-Chiller Duo so you can use one Chiller to chill your milk and one to warm it — making road trips, long walks, and life itself waaay easier! How-to instructions can be found in our product guide.

Always have everything you need to keep your breastmilk chilled: Our Chiller relies only on a splash of water and a handful of ice cubes — things you can refresh easily when you need more chilling time. Verified purchaser Renee, who loves science as much as we do, independently documented how well this works.

Pumping directly into your storage container greatly reduces the risk of spilling or contaminating your precious milk. And the Chiller parts are designed to support double-pumping with no extra bottles.

Our write-up of what to expect and how to prepare shares that “it’s typical to dump the ice and water while they test my milk, then refill it wherever there’s ice available.” Check out this amazing IG reel that shows how the agent will likely test your milk using a vapor strip.

Our Chiller can be used for hot and cold beverages long after your breastfeeding journey is complete. Our Tea-Luxe Premium Tea-Mixing Kit is a great way to get started: Mix your own tea blends in the infuser of the straw top accessory!
