LAMP FILAMENT TEST CHAMBER
This is a tool, that I made to be able run experiments and test various filaments for a custom incandescent light bulbs.
Vacuum chamber is made of two borosilicate glass tubes with a vacuum tight flange connection between them. Two thick tungsten electrodes are providing electricity to the chamber and connected to the tool plate.
