Two cylinder vacuum pomp


Physicians studied air and other gasses and were most interrested in the vacuum. Otto von Quericke invented a primitive vacuum pump in 1654 and physicians started their experiments. We purchased this early twin- or double barreled vacuum table-pump. The two thick wall glass cylinders are vertically mounted on a mahogany base (47x30x50 cm), and with brass gear racks and a brass crank handle. The vacuum cylinder is connected to the glass covered brass bell jar plate on the other end of the base.
The vacuum mercury manometer assembly mounted is situated in the center of the base. The device is in a very good overall condition and can still be used for various experiments.
