DHS08 Suction Cups with Magdeburg Pressure Discs

Objective:

– To illustrate atmospheric pressure.

Apparatus:

  • Vacuum pump and plate

DHS08 - Suction Cups/Magdeburg Hemispheres

Method

When the air space between the two discs has been exhausted, the stopcock closed, and the device removed from the pump plate, it will be impossible to pull the plates apart by hand. If the stopcock is opened, they separate easily.
