Magdeburg Hemispheres, Plastic
Product Code : EL-PLE-11890
Description:
Two plastic, 10cm-diameter hemispheres, each with a sturdy handle, make up this device.
One hemisphere has a gasket seal; the other has a stopcock for attaching to 0.8-1.2cm inner-diameter vacuum tubing.
Join the hemispheres, hook them up to a hand pump, aspirator, or vacuum pump, and evacuate them.
Students will find it hard, if not impossible, to pull them apart.
Open the stopcock to let air in, and the hemispheres separate easily.
Operating instructions are included.
