About the manual vacuum pumps
Our jar seal is designed so that the majority of pumps currently available on the market serve similar purposes (e.g. wine savers and pumps for vacuuming other household utensils, e.g. Takaje, Vacuvin, Le Creuset, Status) can operate.
This means that if the suction part of the vacuum pump can be connected to the seal in an airtight manner, it can be used. In numbers, its inner diameter is min. 24 mm and max. 40 mm.
The amount of vacuum created in a mason jar or other container suitable for vacuuming - taking a manual vacuum pump operating on the piston principle - depends on three things.
- the technical quality of the pump, i.e. how well the piston can seal airtight during operation.
- The other is how precisely and tightly it is connected to the vacuum seal
- Finally, regardless of the above, what is the ratio of the stroke volume of the vacuum pump to the volume of the space to be vacuumed?
By the latter, we mean free space that is not filled with material (food, liquid, etc.).
The higher this ratio favours the stroke volume of the pump, the greater the vacuum and air-tight seal we can achieve and, ultimately, the longer the shelf life of the food.
