microscope

[The_simpsons]

im 16 and im developing a huge interest in microbiology, and im thinking in buying a microscope, but they can be quite expensive, my question is: how strong microscope do you need to be able to see bacteria and unicelluar eukaryotes(sp?). i know the size can vary greatly, but im mostly interested in the bacillus-type. so im looking for something affordable but that lives up for my needs.

i got a 10x/100x/1000x microscope for about £50 and have used it to see blood and skin cells very easily. not sure how big these are in relation to the other cells as i usually use it for observing crystaline structures now.

I one of similiar magnifying power as insane alien that my dad picked up somewhere. I don't remember if actualy paid any money for it.

 

So, check garage sales, and the like. Also, raid the rubbish bins of you local university or lab... those places are constantly replacing equipment that actually works fine. Or write to a professor and them that you an aspiring young biologist who needs a microscope in the pursuit of scientific exploration. You might get lucky.

If you can get one that can interface with your computer you'll ahve n even better time, though it will cost a bit more... Well worth the extra money though becuase the computer adds a hell of a lot of power too it such as resolving small features, accurate mgnification etc.

 

Good luck!

Just an FYI, blood cells are about 6 microns in size, if I recall correctly.

i found a great bargain, my only question si, will 900x be enough to see bacteria?

You should see something, 900x is pretty powerful most things considering

 

Bacteria are between 0.5 and 5.0 μm so you may be able to see then with a 900x scope you should

I have a microscope with a top magnification of 400x (I haven't bothered to get a stronger one because my current research project is focused on extracting and amplifying DNA) and I could see blood cells decently well.

 

900x should be great, and if it's a bargain; go for it. Good luck with your interests; microbiology/genetics are my focus too and I think they're amazing.

he actually stole it from his school

you could post an ad like that in your local newspaper

Yeah... title it, "Biology Genuis in need of a microscope." Someone we know by association scored a free piano that way.
