ZWILLING Fresh & Save Vacuum Sealer Machine Starter Set

A little hard to tell from the picture, but this is by the same manufacturer and looks like the same pump, and the pump by itself is 70$.

(more.rummage) And this one looks to be exactly this set, same pictures being used. The set itself is 80$. So this is a good deal assuming there’s not something horribly wrong with it. Doesn’t say refurb, but doesn’t say ‘new’ either.

Must have updated it, because it says “new” now…

The second link is different product. Note the box is glass.

Here’s the plastic box version:

Does the vacuum work with other brands of vacuum bags/containers, or only their own? (I ask because the containers are $30 for 2 small ones, $40 for two mediums, and $60 for two larges.)

Yikes that adds up quickly.

I’d suspect that these are a proprietary seal, and that this sealer wouldn’t work with other brands. A slight difference in the size or configuration of the bags and containers would mean you wouldn’t get a good seal.

Consider the more generic devices that use a roll of bag material and seal the bottom before you put the food in the top, suck out the air and seal the bags. Those will be much more ‘universal’… as long as you’ve got a roll of bag material.

Fun Science Note: You’re not actually sucking the air out of the containers/bags. Science knows no “sucking” force. The device creates an area of low pressure by pushing the air out of a chamber. It then opens a 1-way valve that lets the pressure in the container push air into the chamber, where it gets pushed out into the ambient air – and repeat.

The bag seems to contract around your food because there’s nearly 15 pounds of air pressure (at sea level) on each square inch of the bag. If the bag is open, the pressure is the same inside and outside. As soon as the bag is sealed and a bit of the pressure removed from the inside side of the bag, the bag walls are no longer supported, and the atmosphere pushes on the bag, making the air contract until the remaining air is again an equal force (14.7 pounds per square inch) resisting the atmospheric pressure.
