About This Product
With the hemispheres evacuated, students find how hard it is to pull them apart and use that to discuss the load air exerts at sea level. Inside the bell jar the class can watch a sound fade as air is removed, see sealed flexible items swell, and link boiling to the pressure around a liquid, while the column and gauge give readings to compare.
Frequently Asked Questions
What does the gauge on the apparatus read?
A two-unit analog dial gauge shows 0 to -760 mmHg and 0 to -100 kPa.
How is the air removed?
A dual-stage manual suction cylinder evacuates the bell jar and the Magdeburg hemispheres.
