Product Description

Classic Geissler Tube Set:

Our interpretation of Geissler's tubes effectively demonstrates what happens when electricity is passed through a high vacuum containing trace amounts of noble gases. The beautiful glow and artfully shaped tubes have been not only teaching tools for over a century, but entertainment and collector's objects as well. 

Once the tubes are energized in the display case, it is almost impossible not to become fascinated with their elegant beauty and function.  

Features:

•   Six unique and hand made Geissler tubes, which contain argon, krypton, helium and xenon.
•   Tubes feature spirals and spheres have been incorporated into each tube for maximum beauty. 
•   Wood display case for operation.
•   A six-position selector switch enables quick selection of individual tubes to energize.
•   Five way binding posts ensure quick and easy power supply connection. 

Operating the Classic Geissler Tube Set:

•   Requires a high voltage power supply. For best results, we recommend either our Classic Induction Coil or Classic Ruhmkorff Coils. 
•   Place tubes in display case holder in any order. This is completely your preference. 
•   Slide viewing window inside of display case. 
•   Connect to power supply. 
•   Once High voltage power supply is activated, turn the switch's position to activate corresponding tube. 

A Brief History of Geissler Tubes:

Heinrich Geissler, a German glass blower of the mind 1800's and inventor of the mercury pump, the first reliable and practical high vacuum pump, decided to see what would happen if he passed high voltage electricity through a high vacuum. Although he was not the first person to pass electricity through a vacuum, he was the first to do so in a high vacuum, thanks to his invention 

He noticed that air started to glow purple, pink, blue or green depending on how much or a vacuum he left in his sealed vessels. So beautiful are these tubes, that they became popular entertainment devices of the day. With the discovery of noble gasses, many instrument makers substituted these for air. 

Later on, Crookes made his own interpretations of the vacuum tube, which ultimately led to the discovery of the electron, X-rays and many other important principles of physics.
