The air extraction nozzle. Why is it written “Don't touch” ?
Because this position is used to link the machine to vacuumize. After Vacuumizing, seal it with special glue. There will be no vacuum leakage.
Last insurance, the cover should be put on to avoid vacuum leakage due to the action of the air extraction nozzle.
The cover can be buckled slightly, and cannot be pressed to the bottom, and a certain distance should be reserved. The distance can avoid internal pressure after the air extraction nozzle cap is closed. Otherwise, the liquid nitrogen will expand and contract and cause the air extraction nozzle cap to crack.
