Structure and function of the electron microscope

[XxXxlethalartXxXx]

Thats my homework done :D

[jackrazalas]

To Carl Sagan: science instead of tv? How about I watch science on tv? Is that still woeful?

[Lolercopterz]

I want one of these in my garage. where can i buy?

[02emma2]

@Lolercopterz cost 1 million dollars...

[Lolercopterz]

@02emma2 K... I didn't ask how much! I asked where! I need one of these microscopes!

[Kan2209]

@Lolercopterz Build one yourself.

[cjbenjam]

@Lolercopterz Hi Lolercopterz! You can buy either a Scanning Electron Microscope or a Transmission Electron Microscope. If you are serious about buying one, you can try "FEI Company". They sell both types. I work with these things all the time, and am currently using both. You won't have to pay $1 million necessarily, and the SEM microscopes are much cheaper. If price isn't an issue as you say, then you can shoot for the higher end instruments which are around a $7 million.

[cjbenjam]

@Lolercopterz Also, if you are truly serious, I can turn this into some type of an opportunity.

[PuRPLeTuTa]

thank you

[newtoninspired]

@FA22raptero yah! it's what they make a guess to identify them, if they could really identify each and every part, couldn't have all the latest theories coming be rejected ?? i meant about their estimation ,sir.

[asemchemist]

It is nice .. this called TEM, by STM you can see the atoms but not clearly. Thanks alot.

[gayboytommy20010]

can u actually see an eletron with your eyes

[newtoninspired]

@gayboytommy20010 No. with an electron microscope , you can see atoms

[nipnipish]

@gayboytommy20010 can you see an electron with your eyes? are you serious?

[quangluu96]

can we make telescope into microscope LOL 10bill magnification

[jui99able]

its good !!!

[ioncita]

tem or sem???

[thanasanter]

It has to be in vacuum because if there are air molecules there are colissions between the air molecules and the electrons of the electron beam. Therefore the beam declines from its direction.

Denne filmsnutten er meget intressant Kristin

[iansquared3]

why does it have to be in a vacuum?

[rauoofali]

Hello, It need to be the vaccume as te direction of the electrons should remain the same and with the same speed. If air is in between it will reduce some energy of the electrons as weel as direction. Hence the sample will not be pentrated well by electrons thus creating blurred image. So vaccum is a must.

Everyone viewing this video NEEDS to youtube Royal Rife and his high powerfull light microscope!!

[skurwiec]

Great vid, but this music is making me sick :P

[randomcomedy94]

@skurwiec lol

[DelongAmerica]

Benchtop electron microscopes are much less expensive than conventional electron microscopes. They are much smaller and can be put in a lab or classroom and do not require special power or cooling. They are also not a sensitive to vibrations.

[randomcomedy94]

@DelongAmerica lol

[TBJvideos09]

Hello Smithers!!!

[bot06]

How is the s specimen placed in a vacuum? Doesn't the glass which holds the speciment reflects the beam as well?

[Jenfucius]

Its not continously a vacuum. I believe its placed in the specimen chamber and then the air is later pumped out.

[jeffykaka]

nice Lol...

[jeffykaka]

get the ancers!!

[xxgamingmasterxx]

disadvanteges:

they are expensive to build

they require extremeely high voltage supplies

they are sensitive to vibration

they need a magnetic field cancelling which means they miht need to be underground

[Jenfucius]

There is no other instrument that can view viruses other than the electron microscope.

[BLVCKB3RRI]

they dont have to be under ground and you can also buy them but agreed they are expensive and a bigtime disadvantage that you left out is that the specimen MUST be dead which limits its use to vieving miving cells and stuff like that

it can also not use color like it said in the vid.

[hyperbob101]

Well, they can photo print it and give an intence visual of the color.

[hyperbob101]

You have no clue what you are talking about do you? they don't need to be underground. And what do you mean buy "they need a magnetic field cancelling which", that makes no sence at all. Ther building structure allows them to be in contact with vibrations. They do have to be built on flat level grounds though. You have absoulutely no understandings of a microscope.

[jeffykaka]

suck it ricky

[jeffykaka]

yea well..noo

[jeffykaka]

hahhahaha

[jeffykaka]

nnoo u need to give me ancers

[jeffykaka]

hey whats upp

[jeffykaka]

u there dylan?

[jeffykaka]

hey man

[jeffykaka]

hey mrs bell

[DOCPTSD]

Now, when and how is the specimen placed into the "tube" so that the vacuum is preserved?

[TirianB]

Annoying music.

[Kusaldiss]

Nice demonstration. Excellently done
