Hello /sci/
I've got a microscope capable of 40x/100x/400x/1000x magnifications.
Theroretically,i should be able to observe bacteria and protists yet i find it very hard to detect any.Why is this so?
I view a small drop of water without any heat fixing or staining.Is this the problem?

where did you get this drop of water?

[Anonymous No.6523912]

>>6523906
Tap

/facepalm

Go outside and get a drop from a puddle, preferably one in the dirt and not on the sidewalk.

Your tap water is loaded with sterilizing agents, for all the OBVIOUS reasons.

You wont be able to see bacteria except as colonies. Protists are no problem tho. You can 'grow' your own by putting some old leaves from the ground into bottled water and waiting a few days.

paramecium and vorticella are quite common, if you want to find amoeba, try to get puddles from very shady areas with no direct sunlight.

Can you get a picture through the eyepiece somehow? I'd like to see what you find

What's the safest method of tearing out an eyelash?

[Anonymous No.6524040]

>>6524039
just put your fingers in a pinch formation gently on your eyelashes and gently pull forward, hopefully one will come out
if not run your fingers through your hair, one will definitely come out and then use that

>Why is this so?

You need to dye/stain your samples to see anything clearly. Normally most things are mostly transparent otherwise.

The basic is "gram stain" for bacterias, and H&E for normal tissue. You can buy them and several other dyes quite cheaply online, and if you do, you need alcohol rinse and preferrably distilled water also.

And buy a box of gloves too, the dyes work excellent on tissue and are quite dark when not under a microscope, so unless you want to have mottled hands; gloves.

OP posted based Carl Sagan. He can do no wrong.

You can see individual bacteria with a good scope but you need a really high quality objective (and at least a 40x, preferably higher) and a really stable scope.

I stuck some subtilis cells under a good scope on a wet mount last year and could see them all zooming around in my sample

[Anonymous No.6524154]

Had some work to do.
Anyways,i tried to take photos but they didn't come out very well.

Here's hair from my head.

you dont need to stain shit to see protists, anon.

OP here.
Any method to grow bacterial colonies using home-made ingredients?
If that's too hard,what are cheap ways to grow bacteria?

Sticks and mud in water by a window. The messier the better. The water will soon turn a nice green. When I was in middle school one of my classrooms had an aquarium by the window with random mud and sticks in it. When we were done with our work we could put a drop of the water on a slide and go to town with a miscroscope. I had a blast, but the rest of my class was a bunch of niggers who played with their dicks until the bell rang. More microbes for me.

Thanks.
Final question:Is microbiology a field worth doing?
I have to choose between microbiology and genetics and can't decide which one.
Currently doing biotech.

Did you seriously think that people realize they aren't actual quotes?

I think genetics is more interesting, and I think you should make your choice based upon which one interests you more
