- Dr. Elaine Ingham gives advice on choosing a microscope for soil microbiology. Dr. Ingham is a world-renowned soil microbiologist who pioneered many of the currently used biological soil amendment techniques and pioneered the testing of soil microbial life as an indicator of soil and plant health. Dr. Ingham is the Chief Scientist at the Rodale Institute. She is the founder of the Sustainable Studies Institute and the Soil Foodweb Inc. soil testing labs. Dr. Ingham is the key author of the U.S. Dept. of Agriculture's Soil Biology Primer. She has been the mentor of numerous soil scientists and practitioners of ecologically balanced landscape design, and has helped farmers all over the world to grow more resilient crops by understanding and improving their soil life.
God bless you for sharing this information Dr. Elaine!
I like the Accuscope 3002 LED for soil compost viewing. It meets all the requirements plus it's compact, portable, and rugged. Not to mention it's less expensive than my Leica and the Labomed LX400
Thanks for the suggestion, question: why do we need the optical eye pieces at all? What about going for screen/camera only option? Makes it a lot cheaper?
Is there any specific function this eye pieces serve that you can't get otherwise?
@@Change-Maker Well prefer to have "mechanical" backup in case the digital side is giving trouble. I've not worked with a digital 'scope yet. But I realize now that I'm going to get one just because of the floaters problem I'm getting with my vintage Nikon 'scope. So there's another advantage of using a screen rather than a eyepiece-at least in my case.
1:24 "ABBE" is not an acronym. It is the guy's name!
Ernst Karl Abbe HonFRMS (23 January 1840 - 14 January 1905) was a German businessman, optical engineer, physicist, and social reformer. Together with Otto Schott and Carl Zeiss, he developed numerous optical instruments. He was also a co-owner of Carl Zeiss AG, a German manufacturer of scientific microscopes, astronomical telescopes, planetariums, and other advanced optical systems.
Help! Is their an update? I can’t find a microscope with all the features mentioned in the video. Even the M8311. The shadowing or differential…
did you find one
@@treymurphy6398 I gave up looking
@@queuemaster Don't give up buddy!
You don't have to get DIC, it's overkill for soil analysis. I use SWIFT380 and it's perfect for the job (got it at 150$ US, new/open box shipping next day inc.)
There is other great scope in this price range such as AMSCOPE.
What is important: ABBE 1.25 condenser + adjustable diaphragm, LED, mechanical stage and binocular (trinocular if you wanna do picture with DSLR). I have the binocular and use my phone to take video or photo if needed.
Look at MicrobeHunter to get more info.
THIS IS SO HELPFUL! Thank you!
This was extremly healthy! Thank you so much.
Anyone signed up for the class yet and got a new recommendation for a Microscope and Camera Combo?
I’d like to know too!
2023!
Hi Dr Elaine could you please recommend a good microscope for soil biology as there seems to be so much choice. I definately need to be able to take images ideal linked to a dslr camera for high resolution. Many thanks
You could use SWIFT380T or similar. 'T' stand for trinocular. So you could but your DSLR in that third hole.
I do have the SWIFT380B 'B' for binocular, and it's perfect for my sol analysis. (I paid 150$ for new/open box on Amazon, from Swift).
Well crap. I acquired an old Nikon from University surplus, cleaned it all up-and began looking at things. 40x and 100x are pretty easy to deal with but when I go to 400x the floaters in my eye become the most fascinating thing in view. I've dimmed the room lights to help, but it doesn't really. Is there any way to reduce the visibility of my own floaters?
Recently heard that the supplement MSM helps clear up floaters. Check out Dr. Berg here on UA-cam.
In Chinese Medicine, they say that floaters are usually a Liver related issue. After going to an Oriental Medical Doctor (OMD or DOM, Doctor of Oriental Medicine), I no longer have floaters. The Liver has a major influence on eye health. Liver is capitalized in Chinese Medicine because it includes much more than the liver organ. I hope you can resolve your floater issue.
@@bobbiejofouts1708You do know that chinese medicine is not science, or medicine, right? It's spiritual metaphysics and folk myths. Do you also recommend trepanation for headaches? WTF???
@@thetruth45678 this all depends on how you define medicine. They use a reasoning to figure things out, like inductive reasoning. The scientific method is not the end all, be all in figuring things out. If they did not help people get well, the doctors in many areas of China would not survive. In their culture, if someone gets sick while under an Oriental Medical Doctor's care, the doctor ceases to be paid. It is not some kind of backward mysticism. Yes, the West presents it that way to drive people away from that healing. Westerners primarily treat the symptoms they call disease and falsify studies to ruin us. And, we think we're so smart.
@@bobbiejofouts1708 It is not medicine or science. It is metaphysics and folk myths. Your anti-west lies are not going to win any converts. Kick rocks, Lee.
Isn't this just regular bright field? If i'm not mistaken differential interference contrast microscopy requires polarization and prisms and various other components...
Can someone PLEASE tell me what she means when she said "Shadowing or Differential Interference Contrast"
I really don't want to get something that will barely work.
I dont think she means darkfield, and DIC is hard to find or too expensive.
I've been looking for months. i have talked to dozens of people and no one can give me a straight answer.
You are right, it is DIC, but it's overkill for soil sample. A general bright field like SWIFT380 is perfect for the job. You also get a small filter holder to put a darkfield filter (DIY) and get even more option.
Levenhuk 400B you can use
You're the best!
Thanks a lot,
Looks like they are at least $450. Not what i call inexpensive... is there not anything that doesn't cost as much???
I can't find them in the 180 range. Keep looking.
3:15 ALL SPECIFICATIONS IN THIS MINUTE. COST $350
BINOCULAR
10X WIDE FIELD
4X SCANING LENS, 10-20X & 40X OBJECTIVE ( TOTAL 400 )
ABBI CONDENSER 1.5 MINIMAL
It says Numerical Aperture 1.25 for the Abbe condenser, not 1.5
@@onegrapefruitlover I got a SWIFT380B for 150$ US, new/open box.
Work perfectly for soil analysis.
Thanks - anyone in the UK found any similar?
Anything?
Don't remember commenting but yeah suppose I did 😂
whats better halogen bulb or LED?
halogen is better for your eye health.
LED is better for specimen, it won't harm your preserved slides
this video has no audio?
Audio only in left channel.
LOL
Would I be better of with a swift SW380B 40x-2500x, or an Omax XM82ESC02 40x-2000x????? Choosing one now!
How is your choice turning out for you? I am browsing options now. Thanks :)
@@2HAYEZ works great, I kind of want the camera now tho lol. And I definitely need to take courses, I cant teach myself to identify microbes online nearly as adequately as I hoped I could, classes are definatly necessary.
I need to get on it asap too, cus somehow I'm having major problems in my garden. I thought I gave them all they need and more but somems real messed up.
@@trevorfichtner3539 what microscope did you end up choosing? Yes i look forward to taking the class.
@@2HAYEZ I went with swift SW 380B
Ppl comparing that one to the old 350 B, which is still supposed to be real good, but like 50 bucks more for the new one and everyone loves it, I know I do. Image is very crisp, easy smooth slide adjustment too. I dont think I would have been happier with any other option this thing is pretty nice. I mean I dont have much experience to compare to other ones but, I'm more than happy with this one I'll tell ya that.
@@trevorfichtner3539 great. thank you for the advice. i wish you and your garden the best of luck.
So wait, is she talking about darkfield?
No.
@@garthwunsch
Please, would you care to clarify?
She said "shadowing or Differential Interference Contrast as opposed to Phase Contrast"
I genuinely dont understand what 'shadowing' means. DIC seems hard to find, and if i do find it, its really expensive.
Yeah, took me months to figure all this out
You want a brightfield, preferably one that can do DIC. Dic is much much better, but it will raise the price tremendously. Brightfield should work well enough
