Nice size for chamber VP112S without vacuum port
You can set the knob to vacuum or just a little beyond and put in the vacuum chamber. Set the VP112S so it doesn't try to seal a bag, close the lid and press start. Once the vacuum releases open the chamber and turn knob to Lock. Done.... I also have a Jaccard hand vacuum pump and I was able to put it on the top of the knob and draw a vacuum on the canister. Nicely made canisters....
