Giant glass diffusion pump and cathode ray tube demo





This vacuum diffusion pump is made entirely of glass so we can see how it works. I also show a CRT built from a glass lab flask. The pump was bought on Amazon! https://www.amazon.com/Vacuum-Diffusion-L-2210-Three-stage-Four-stage/dp/B07MJ2RQ44/ Diffusion pump instructions translation: https://twitter.com/BenKrasnow/status/1170188966642896896 I used DC-704 silicone diffusion pump oil: https://www.duniway.com/catalog/diffusion-pumps/diffusion-pump-oil The tabletop burner and fuel are commonly found at Asian supermarkets.
