Intro to plasma cleaning

I describe how to use plasma to create very clean surfaces on microscope slides. This process is used extensively in the semiconductor industry.


  1. Great video - as always. Could make a video on gluing and adhesives ? for example You could try gluing PTFE by epoxy after activation in plasma chamber ? i want to know if it works, but i do not have plasma chamber now.

  2. Boy this brings back memories!! My father worked for the Surface Activation Corporation in Syosset, NY during the 70's. I clearly remember visiting and seeing giant cross-shaped bell jars glowing with all sorts of cool colors inside. They tested many gases and I recall once they tried Hydrogen and Oxygen together to see what would happen, but were kind of unsure of the result once they hit it with RF, so they hid in the next room with a long extension cord in case of any non-passive event!
    Apparently nothing exothermic occurred, just wild colors swirling inside. Great memories of way back then!
    My dad was friends with John Fales and Boris Levy, both of whom I believe were instrumental in creating this process. It was a great time for me to discover the world of science and see first hand the amazing stuff going on there.
    I remember John Fales' basement at home, loaded with all sorts of mad-scientist equipment! So much fun to se all his tinkering. He gave me one of those solar spinners, something I've cherished for a long time and has always why I love and appreciate science.
    Thanks for this Ben!

  3. Andris, that's a great story. Thanks for posting!

  4. Ben, thx for posting...I used almost the same method..but with out the rf...just using high voltage..on microscope sides before coating them with pasted the "tape text"!
    Have you seen any videos posted by Ron Soyland aka "Glasslinger" on You Tube? Like "vacuum evaporating a metal onto glass"?

    Ron does a lot of great stuff with glass blowing...but I think he might have fewer outgassing problems if he wore gloves even when working on the insides of turbo pumps. I'm sure that he would be happy to hear from you about how he could make improvements on his vacuum systems.

  5. Carl, yes Ron's videos are pretty interesting. He has a lot of vacuum tube experience, and makes some really cool stuff. I've exchanged messages a couple times with him.

  6. Ben, great introduction to plasma cleaning. Have you seen this new magna plasma cleaner that does not require any CF4 gas? Would you use that in an industrial application?

  7. I have seen this video several times and it is equally entertaining each time and inspiring. your channel is the inspiration that has made me starting to build my own vacuum set-up.
    Any recommendations on where I can get more in depth information to build a cleaner and vacuum system?
    plan on experimenting with sputtering, evaporation and plasma nitriding metals for different applications.

  8. Hi Ben, I discovered you recently, and I must say I am a huge fan, what you are doing is just amazing...
    I am trying to understanding your setup, maybe I’ll try to build one myself once I understand it fully. Can you explained a litter deeper how you connected your electrical gear, specially the tuner part, I can’t understand its role and how it is connected.

    Thank for sharing your knowledge.
