Complete set of equipment for conducting Guericke's
historical experiment to show the effect of atmospheric
pressure. The experiment can be performed as a dem-
onstration or as a student practical.
1. Safety Instructions
 Do not try to pry the two evacuated hemispheres
apart using tools.
 Do not try to separate the hemispheres using ropes
or similar, because when they do separate they can
turn into projectiles.
 Ample space should be left behind the persons try-
ing to separate the Magdeburg plates
 Do not use excessive force when connecting the
hose. Do not use any more force than you can gen-
erate from your fingers to connect the hose.
 When ventilating the hemispheres hold on tight to
the apparatus so that you can avoid any damage
from the hemispheres falling.
 Be careful not to scratch the inner surfaces of the
plates.
 To clean, only use warm water with a small amount
of washing-up liquid. Never use solvents.
Description, technical data
The Magdeburg plates kit consists of two transparent
acrylic plates with handles and a rubber sealing ring to
be placed between them. They can be pushed to-

gether with a coarse vacuum between them. Sealing
rings of two different sizes allow comparison between
the effects of atmospheric for two differing contact areas.
One plate is equipped with a flange for attach-ing a
plastic hose so that a vacuum can be generated.
Evacuation is performed using a simple hand pump. This
can be connected via a plastic-hose with a built-in valve.
An additional T-piece allows a pressure sen-sor (e.g.
U44220) to be connected for measuring pres-sure in
conjunction with a suitable interface (e.g. LabPro
U44000).
The advantage of the Magdeburg plates over the hemi-
spheres usually used in lessons is that, due to the flat
design, all forces act parallel to the plates allowing the
forces to be calculated easily.
