Hey if someone is using the equipment for pleasure and raw curiosity, I see no issue here. Just because he’s the janitor doesn’t mean he’s not entitled to discovery.
Oh wow. Didn’t know that. I saw a kidney biopsy in an electron microscope before but I never really learned how they worked because I figured I’d never work with one.
They’re super cool! The reason for the vacuum is that electrons are much more likely to scatter in atmosphere than photons, so you want as little air present in the chamber as possible. Also many microscopes generate their electron beams with a heated tungsten filament (which is soo expensive), so iirc the vacuum prevents it from burning up quickly.
Electron miscroscopes often have a “low vacuum” setting for when samples can’t be subjected to such a high vacuum. Usually you need some training before anyone will let you use their electron microscopes.
Electron microscopy is usually used for kidney specimens right? I don’t get the joke intended with the picture though
It’s just the janitor fucking around with the equipment after hours.
Guess I just missed the joke. I have a lab background so I probably am looking at this whole thing too literal

electron microscopes usually operate in a vacuum. If you put organic stuff in there without properly treating the sample, it will damage the equipment

Wow thanks for the information. An electron microscope has to be the coolest microscope. The images I’ve seen were always interesting
If they’re in vacuum, they probably are pretty cool! Other than that tungsten filament that other commenter mentioned, apparently.
