what kind of bacteria can you see with this? can you see DNA/RNA strands ?

Actually, you can see DNA if you prepare your sample for it. I am able to see mitotic chromosomes easily using a 40X objective, but that is with special slide prep where you treat cells with hypotonic solution and then spread them on the slide and fix the chromosomes onto the slide. You can also use acetocarmine to stain DNA. But again, it depends on being able to find mitotic cells. You will not be able to really see nice DNA if the cell is not dividing. If you are looking at plant samples you can check the root tips or anthers, but you may need to digest the cell wall.

DNA/RNA?!? Dream on! You need an electron scanning microscope to see THAT small! Uhh... if you weren't aware of this, the DNA is _INSIDE_ the nucleus of the cell. The AmScope microscope, at it's higher magnifications, will allow you to see single cell organisms but certainly NOT details of the interior cell structure.

The field on this microscope in bottom lit. So you can see anything that the light can shine through. It will also illuminate small insects, their wings, legs etc. Quite alot of the body of the insects are translucent, so you can see inside the bodies etc. I have also looked at blood samples (my own) and it shows the blood cells, and white cells and other scary little critters swimming around in there. I had a microsocpe i gave to my grandaughter that also had a light that shinned from above. This would be nice to have on this one, but does not. with a top light you could look at objects that the light will not shine through. I especially like the camera/computer hookup. I hook it to a 32 inch tv and it gives a great picture of the object and you can take moving videos of little critters, like in pond water, or even small blood samples. the camera and software came with the scope i bought. this scope has four lenses. i use the lowest and next highest the most. that is the .4 and the 10 (which are then magnified by the optical by which ever lens you put in. this scope came with two options. The third lens is a 40, i have a little trouble focusing with this one, you have to get really close to the object, so make sure you use a cover on the slide over the object so you don't get stuff on the lens. And the fourth lens is oil emersion, a small bottle of oil comes with the scope. I think if i where doing it again i would try to find one that is both bottom and top lit. Not sure how that effects the price. Over all very happy with the quality of the scope, I would give it a 9.5 on a scale of 10. Have fun.

Hi! Yes, such as pond water creatures- diatoms, paramecium, and such. My son also did a cheek swab, and checked out those cells.

More media depending on your needs. I've loaded mine with lava rock which promotes 2 types of beneficial bacteria. Anaerobic and aerobic bacteria.

I can not answer that. I gave this to my grandson and he has not tried blood. Sorry. However I can tell you that they have enjoyed looking at other things such as pond water and they could see stuff in it.

It will show you bacteria and other chemical contents. Not sure whether bad taste reason will be exposed by it

Live blood analysis is usually done on a dark field. But you can certainly use this microscope to look at blood cells. It's a great scope for the price.

Yes....I just checked out my bathroom. You can see everything! Urine, toothpaste, soap scum and globs of hand lotion. From now on, I'm cleaning with the black light!

You put the water sample in the small bottle, being careful not to spill the powder in the bottle, fill to 1/2" below the top (cold water side), shake well, place on shelf and in 48 hrs, if it turns a yellow color, there's bacteria present, violet or blue, no bacteria. It does not tell you specifically which bacteria. Some reviews have reported a yellow/blue result, so it's inconclusive (my tests have all been pretty conclusive). If you get that, you might have your water tested professionally for a conclusive test. Only one test is included for each of the variants.

I'm not sure about what UV light does to mites, but I do know that Bacteria and other single-celled organisms are affected by this device.

"Germs" is a term that includes many different organisms. Bacteria, fungi, viruses, and protozoa often all get lumped into this category. There are good (beneficial) organisms as well as dangerous ones. Unfortunately, the beneficial and harmful ones do not follow any specific pattern of fluorescing or not fluorescing under UV light. I've had lots of fun looking at dust under blacklight. You would be amazed at how much of it lights up-- including bits of paper.

Yes you can see it. I run vinegar through it to clean it per instructions. Hot steam seems to clean everything.

Germs are microscopic, but it might reveal colonies of bacteria. I guess many organic fluids, such as those our cats secretly secret around the house, are entirely evident with this light, especially when you also use the tinted googles.

The test kit will turn green in the presence of coilform, which means you need to treat your well. The black light is needed to reveal e-coli, but if the sample turns green why bother?

I found this website very helpful in regard to your question: http://www.thesilveredge.com/bacteria.shtml#.VSVv9tzF-So

No..this device is very stubborn. Only works on specific units. You're allowed(sometimes), to view media being played(output). DNA device

They are coated with something, mine were planted this april and are now blooming. The inoculant is to promote nitrogen fixation, and the ground likely already has this type of bacteria already.
