Customer Q&A Ask a Question

How do high altitudes affect the vacuum sealing process?
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.
How do I determine if a vacuum machine bag will work on my machine?

If you have a chamber-type machine: Buy a chamber-type bag (mesh-less design). The open end of the vacuum bag must be 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 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.

Hi I'm Philip Preston, President of Polyscience, and this is our 300 series Chamber Vacuum Sealer. Chamber vacuum sealers offer the advantage of allowing you to use liquids in the bag. This unit features full adjustability of vacuum, seal time, and also we've incorporated three user setable presets. To use the unit you simply open the lid, place the bag inside over the seal bar, and close the lid. You could run a custom cycle. In this case, I will select P1 which would be the setting for high vacuum and normal seal time, and then I simply press the start button. This unit features a dry piston pump, so it's maintenance free. Typical professional machines utilize an oil pump which requires an oil change periodically. We've also incorporated a marinade feature in this unit, so it can run a vacuum cycle, hold for a period of time, release, reapply the vacuum cycle over a period of time to give optimal marinade. The unit also has an external vacuum port, so it can be used with canisters either for dry storage or for pickling. It's very simple to use, compact, and is the perfect cost-effective solution for the home cook.
