- I will attempt to clean a microscope objective, which is in a very bad condition.

@Microbhunter May I suggest one day to make a 4-5 minutes video about the ergonomic of using a microscope.
For example, put the scope on book or something to get the eye piece at the right high. To avoid bending your back and get pain. How to dispose stuff around you to be efficient.
Med Tech of over 40 years in labs and the industry. I had a lab very proud of their maintenance regime, but couldn't understand why their low pwr (20x objective) was so blurred relative to high pwr. I had to beg to use Pathologists private scope and showed them a good one. The maintence guy had been putting lens cleaner on the lens & TWIRLING a cotton tipped applicator on it! This destroyed the lens but they had no idea until I counseled them. My heart sank when I first saw it done, had to bite my tongue.
Ein kleiner Tipp: Anstelle eines Zahnstochers würde ich Wattestäbchen mit Papierschaft verwenden. Den "Wattekopf" kann man dann mit einer Schere in einem engen Winkel abschneiden, dann ist der übrig bleibende Papierschaft sehr fein und spitz aber dennoch weich und auch saugfähig. Den kann man dann in Alkohol eintauchen und damit wirklich jede Stelle in der Optik erreichen - und braucht dabei nur sehr wenig Flüssigkeit, ist also wirklich ungefährlich. Je nach Verschmutzung ist es auch eine gute Idee zuerst mit einer Mischung aus destilliertem Wasser und Spülmittel zu arbeiten, denn damit lösen sich viele Öle und Fette, die sonst auch nach Alkohol und Feuerzeugbenzin überbleiben würden.
I have been occasionally giving my objectives small puffs of canned air to knock off any loose dust, all seems well, I can see cilia and flagella in bright field. I don't think I'd have a choice but to clean it if I got anything that wouldn't come off this way, so thanks for showing me this method. Hope it doesn't come to this.
Is it safe to assume that one should avoid cleaning an objective lens in an ultrasonic cleaner?
Hello @microbehunter_microscopy .. I've been following you since I was in masters..now i am a research scholar too..Your skills are impressive.. I have a question regarding lense.. Can you please tell me how to clean the lens which is showing granular particles while shooting videos from microscope..
What is the difference between coaxial and regular microscope?
Not gonna lie you look like Rowan Atkinson sometimes when you smile, the photos of him in his early ages in black and white 🖤 🤍
Rowan Atkinson, I agree..
Fun fact, he have a very high IQ.
Both brilliant humanist, we are blessed to have access to their talent.
@@alexandrevaliquette3883 absolutely 👍
Hi can i know how to open or fix a loose X knob? Mine is cx23.
The X knob works fine on clockwise movement but it need extra turns counter clockwise, otherwise the specimen holder wont move normally as the clockwise. Please help thank you
Please lemme know about foldscope vs compound microscope 🔬
Hi, interesting idea with the toothpick.
For Olympus objectives I believe they recommend this ether/alcool mix, but I have no idea were I can buy this?
PS: I'm in France.
I once got it from a local drug store who mixed it together for me. Use alcohol/ethanol without additives. 70 ether : 30 alcohol.
@@MicrobehunterMicroscopy Thanks, I'll see if I can buy that to my local drug store. Otherwise I guess I can source ether / alcohol from internet drug stores ?
Hi microbe hunter, I have a question. I use an introductory microscope which can achieve maximum magnification of 320x, If i use a 30x eyepiece with my 20x objective (which is the highest objective I have) the total magnification will be 600x and if I use 25x eyepiece with my 20x objective the total magnification will be 500x. My microscope is telmu XD-1606 inverse microscope, can you please tell me which eyepiece would be compatible with my 20x objective. I need atleast 400x magnification, Thanks in advance btw love your videos
You need to get a 40x objective to combine with your actual 10x eyepiece. A more powerful eyepiece will give you horrible image quality.
You want a high magnification of a clear/sharp image. If you get a 30x eyepiece, you will get a high magnification of a low resolution image: a bad useless image with no sharp details.
This is the most common beginner's mistake (I did it too).
I've look at your TELMU scope... Unfortunately, you can't upgrade the objective. Even if you could, you don't have a condenser and therefore the 40x objective will be deceiving.
I still think you should not buy 30x eyepiece because the image will be horrible/worthless. The 25x eyepiece should already be quite bad; 30 will even be worst.
Save your money, and buy a better microscope would be my advice. Maybe consider borrow one at your local school, university or FabLab?
A good way to get 400x is 40x objective and 10x eyepiece.
@@STEAMChannelOfficial I invite you to read my previous comment. His scope won't support the 40x objective.
@@alexandrevaliquette3883 Oh ok
It's 4h AM and I'm looking at manure compost!!!!
I just got my new SWIFT 380B few hours ago and can't stop tracking all the living creature on my slide!!!
First, I've looked at a Canadian 20$ bill. Lot of colour, safety protection and unexpected texture in 3D ink!
I was quite happy with the overall build quality and amazing picture with 4x and 10x objectives. Not so much with 40x (I later realise it's because I was in air, not water yet)
Then, soil sample #1 (dry soil/dirt mixed with water)
Beautiful sand crystal and general soil structure. And I found my first UFO!
I don't know what it is, but it was small and flying all around VERY fast (could barely track him at 400x). It was a great workout to get used to the left-right-up-down-focus and switching objective when I lost it.
It show good picture quality on 40x objective. Honestly, not as good as I hope for, but still can't complain for 203$ Canadian (138 Euro or $147 US) (shipping Included).
I still have to make some adjustments/alignment and a DIY darkfield to get the best experience from my hardware.
BUT THEN....
I switch to soil sample #2 (3 years composted organic horse manure mixed with water)
Brouaaaaaaaaaaaaammmmmmmmmmmm! A gazillion of theses UFO flying in different direction like there would be no tomorrow!!!! I laughed out loud!
I've watched A LOT of soil microscopy on RUclips and I never saw such high concentration of life... EVER!
There was way too many different kind of living thing per mm2: paramecia, ciliate, many different moving or not moving bacteria and algia, polen, yeast, fungi/mycelium, soil cluster, various living diatoms, various slow/very slow/fast/very fast moving hunter of different size and form, blob kinda thing (look like white blood cell) and the list goes forever and forever!!!!
All the above within 4cm2 on the slide's surface or less than 0.001 g of solid compost sample on the slide. I have a metric ton in my garden; I wish they all pay one cent each for the rent!!
For anybody who have access to a microscope, go find your local farm and look for old composted manure (or maybe the commercial bagged version is decent quality?)
If you like this chanel and don't have a microscope yet; get a SWIFT 380 (or similar price range microscope) and a box of 72 slide + 100 cover slide.
We should take a moment to realise...
I'm almost 50, living in Canada. I'm so thankful to live in a time where high technologie and knowledge is affordable. Internet, free access to knowledge, computer, camera, microscope, phone, 3D printing/laser, endless free software/application, youtube, wikipedia, universal language (english) to share with different culture, arduino, medical health, plane, space exploration, wifi, car safety, freedom of speech, new variety of plants/fruits and the list will never stop.
When my grandmother was a kid....
Most of the above was not even in the wildest sci-fi book!
I won't be there in the next century or millenium... I can fathom what will be the reality then. Maybe they will get that dam hoverboard or flying car working with anti gravity instead of lame propellers!
If you read this, you probably have less than few decade to live... So, have fun, try new thing and enjoy life as much as you can.
