Lava preserving jars with aluminum lids

Set of 6 - 0.75L

These glasses can be vacuumed   quickly and easily, with the Lava vacuum bell

quality glasses made in Germany, without clips and rubber rings, instead with a specially coated lid and screw ring.

When the glass has been properly vacuumed, the lid pulls inwards and does not give in at the touch of a finger.

Handling the vacuum bell with a lava preserving jar

Connect the vacuum bell to the lava vacuum device and vacuum in container mode. The lid of the preserving jars is in two parts, first only put on the lid part without a ring, now put the bell over the lid and vacuum it. Remove the bell at maximum vacuum. Finally, screw on the aluminum ring of the cover - done!

So you can extend the shelf life of food and 5-10 times. Incidentally, also ideal for boiling down, because you can achieve a high-quality vacuum in the glass, it is only important that you let the contents in the glass cool down before you vacuum.
