Good for you! So daddy can afford a SEM.

[SCIFIaction]

@Nomoreidsleft Ha we got this for around the same price as a plasma. We don't have cable either.

Your aperture isn't aligned right - at 2:57 the image is shifting up and down as you focus.

Nice piece of hardware and certainly beats the light microscope I have in my living room lab. Definitely looking forward to getting one of my own (though I doubt I'll be able to afford one nearly as nice as the Zeiss Supra 55 at school...)

@nemesisgeek Ha thanks! It's nice to hear from other enthusiasts

that looks like your just one nuclear accident away from becoming a super villain

@ellion0815 Имейте в свой​собственный бизнес у меня будет все КГБ на вас, как водка на льду

sure beats a piano in your living room

where did you find that thing?

@SCIFIaction - have you serviced the pumps yet? You should really change the oils yearly - the rotary pump is simple, just like a car, the turbo pump a little more work as you have to remove it.

To remove the turbo you need to pull the cover off, remove either the electron optics or vac control board and then undo the turbo to rotary pump hose, electrical connector and finally the 3 or 4 clamps that physically holt the turbo to the bellows on the base of the column.

@daithmac23 - Cambridge Instruments went on to become Leo Electron Microscopy in the 90's - who were then bought out by Zeiss later on.

To the comment about the stage/stepper motors - it already has motors on the XYZ axis it doesn't have T & R motor drives though.

[daithimac23]

Its a Cambridge Instruments 240. The company went on to become Zeiss.

@SCIFIaction "goggle translate" is funny.

Respond to this video...  labx dt calm sorry.

@Nomoreidsleft they aren't that expensive. labs dot cm has a number of them for under 10 grand.

As an advice, wear gloves when you put your sample into the chamber. You don't want to contaminate your sample with the oil in your fingers, which also makes pumping to vacuum more of a challenge for the system.
