The Fresh & Save La Mer vacuum pump is at the heart of the smart storage system by ZWILLING. Featuring a beautiful sea-inspired design, the sleek, quiet vacuum pump extracts the air out of our vacuum containers and bags in just seconds and preserves aromas and vitamins. It stops automatically once a sufficient vacuum has been created. The La Mer vacuum pump can be charged using the included USB cord. With the Fresh & Save system, you can shop once a week and refrigerate or freeze fresh fruit, vegetables, meat, and fish in our vacuum containers and bags and enjoy the benefits of your own fresh market at home. Prepare your meals days in advance and enjoy them as fresh as the day they were cooked. Cook meat sous vide or marinate meat for the grill in just 30 minutes in the vacuum bags and containers. Here's how it works: Dock the vacuum pump onto the container or bag valve and at the push of a button it extracts the air in mere seconds. It stops automatically once a sufficient vacuum has been obtained, locking in flavor, aromas, and vitamins.
