This Vacuum System allows to use Bell Jars of several sizes. I use kitchen glass bowls as bell jars. The base is an aluminum plate of 10 mm thick. The gasket is rubber from an inner tube from a car tyre. The connectors and valves are GAS 1/4 thread. The four (4) spark plugs give electrical isolation and air tightness. Each one is connected to a banana conector (banana socket). This provide an easy way to use the chamber with detectors, sensors (i.e. electric conductivity pressure sensors); electrodes for plasma arcs, cathodic rays, X-rays, triodes (thermionic emission), etc.)
