Galaxy Sous Vide Starter Kit with Vacuum Packing Machine, Immersion Circulator, and 5 Gallon Water Tank

Yes, if the mason jar fits, you can put it in your machine. However, it is not a substitute for canning.

These vacuum packaging machines are not recommended for use with retort or Mylar® packaging; instead, we suggest choosing from our wide selection of vacuum packaging bags for best results! Retort and Mylar® packaging requires special plastic and foil laminated pouches to seal food safely.

A vacuum sealer’s performance varies with respect to location. At higher altitudes, where air pressure is less dense, vacuum sealers are unable to remove as much air from the sealing process. High-pressure conditions are an important factor in the proper functioning of the sealer’s compressor, and without enough pressure, you may notice a weaker vacuum.

If you have a chamber-type machine: Buy a chamber-type bag (mesh-less design). The open end of the vacuum bag must be the same size or shorter than the seal bar on your machine, and the bag must also fit inside your machine’s chamber.

If you have an external-type machine: You must buy an external-type, or "out of chamber" bag (mesh design). The open end of the vacuum bag must be the same size or shorter than the seal bar on your machine.

All of our vacuum machine bags list how large the open end is, and whether you can use them with external or chamber machines, in the content.
