With the practical vacuum containers made of Syrol-acrylonitrile and an ABS plastic lid, food can be preserved for a longer time. The vacuum containers from SOLIS ensure effective shelf life extension, helping to prevent food and money waste. A vacuum hose is included to facilitate the vacuuming process. The vacuum pressure indicator allows for monitoring the process. The containers can be stored in both the refrigerator and the freezer. Thanks to a vacuum valve and a silicone seal in the lid, food can be kept there for an extended period. A date indicator reminds you of the vacuuming date. The vacuum containers have been tested and approved by the SQTS Institute in Switzerland.
