Atmospheric Pressure<br />
Magdeburg Plates<br />
SE-9717<br />
Air is evacuated using a syringe; no vacuum pump needed. Clear<br />
plastic design lets students see everything. Two different “O” rings<br />
allow two different size areas.<br />
Atmospheric Properties Chamber<br />
ME-6813<br />
P Recreate the conditions that lead to cloud formation<br />
P Measure changing temperature and pressure<br />
P Built-in Fast Response Temperature Probe<br />
Add a small amount of water to the reservoir at the bottom of the<br />
chamber. Then seal the chamber, and press the rubber stopper into<br />
place on the top of the chamber. Students add pressure to the chamber<br />
using the included syringe. When the pressure is high enough,<br />
the rubber stopper will blow out and a cloud will form.<br />

Magdeburg Plates Accessory Kit<br />
SE-9718<br />
When added to the<br />
Magdeburg Plates,<br />
these accessories provide<br />
a vacuum chamber<br />
in which balloons can<br />
be inflated or water<br />
made to boil just by<br />
evacuating the air. A<br />
suction cup will lose its<br />
“suction” when the air<br />
around it is evacuated.<br />

Atmospheric Pressure<br />
Demonstrator<br />
ME-8966A<br />
12”<br />
Includes<br />
0.95 cm thick, 9.7 cm diameter circular polycarbonate plate<br />
6.5 cm tall, 7.5 cm diameter cylindrical acrylic pipe<br />
80 cc plastic cup, two small balloons and a suction cup<br />
Demonstrate the effect of a<br />
pressure differential. Easily lift<br />
a box or stool by simply placing<br />
the rubber sheet on a smooth<br />
surface of the object and lifting<br />
up on the handle.<br />
As you pull up on the handle, a<br />
low-pressure region is created.<br />
