The peristaltic pump has a strong self-priming ability to transport air. This video shows you the ultimate degree of vacuum that can be done with a peristaltic pump.

The ultimate vacuum of the peristaltic pump is affected by the dimensional accuracy of the peristaltic pump head and the material and size of the tube. The higher the accuracy of the pump head, the greater the vacuum achievable. We can see in the video the peristaltic pump head can reach the ultimate vacuum of -0.099Mpa, for the users' reference.
