Was looking for System of a Down, but this is interesting, honestly
Wow very interesting, thanks for uploading.
Hey. Some of meats always cling to bones seem similiar to this! So they were part of the spine!!
So after getting 755.3 mm you subtract it by 2.6 and the correct pressure should be 752.7 ?
Wat kind of oil?
mScope ML-A-A Microscope Immersion Oil and you need kimwipes lens cloths and Hexane to clean the lens after you use it.
FUN!
Thank you! Some real science for a change!
Thank you, just what I need for my first ever college experiment (which will be conducted online, sadly)
👍🏻
love the "bleh" at the end
You should never rub the lens that has been immersed in oil. The trick is to dab it with a special paper until its oil free.
Mam.Is this real spinal cord
The barometer in your video looks identical to the one I have. It's a "Fisher Scientific" Do you know how I can find its value. Thank you in advance. And...I learned so much from your video. Very nice!
Pls more videos on microscope
We've all been tricked
Thank you. Nice video!
This lady is all over the place oh eaut i forgot its community college
Ma'am I have a question. Can we use any sort of oil or is there a specific oil only meant for this job?
You should use an immersion oil that has a refractive index equal to the refractive index of the lens.
Did you cook it after the demo?
Don't eat spinal cord and brain part of cow. It can cause you mad cow disease. Humans once infection cannot be cured. Patient die within a year.
She fried it with garlic + butter yum yum spinal cord a tasty snack [joking]
Can’t say it didn’t cross my mind
Thank you for this information
1:18 did you use prepared slides to demo the oil immersion? Prepared slides are only designed for dry objective. 😂😂😂😂
That is incorrect.
Thank you 🙏
why are you wearing glasses?
Sound is not proper clear
Thank u sweetie
TC DC isase kaise pata lagate hai
weird flex but ok
was looking for system of a down, but this is fine I guess
😂😂😂😂😂
i was looking for a system of a down song...
DarkPeter i was looking for thoracic viscera.
Same 😂
This was, maybe a best tutorial on microscopy.
thank you for the education. .very interesting information..!!!
Thanks for this informative and easy to understand video! You are beautiful, by the way.
Thanks that was very helpful
Ha ha
Am a spinal card injury pls hepl
@@princessgdprincessmarkus1779 Spinder.
No am srs! Back in like 2011 some clear spike tech was implanted in my neck & I was zapped by some kind've interdimensional being 2 years later that caused it to start cracking & now there's all these things people call "Mandela Effects" I didn't know about before & I can still feel it doing stuff that sounds all "zlitchy"! >;O
Beautifully represented, Jesus bless yah
What do you do if you get immersion oil on the 40x??
clean it
Very clear 👍🏻
Very well done; taking off the immersion oil with a real lens cleaning paper, but when you are not sure that your 100x is clean ALWAYS use a good quality lens cleaner (like ROR) to really clean your frontlens! NEVER clean it dry! RoR is one of the rare cleaners that really resolve parts of immersion oil, instead of dilliputing it!
WHY are you wearing protective goggles? The barometer won't bite your eyes.
Because to protect the eyes form covid water 💧 19
It’s standard to always wear safety goggles in the lab, whether chemicals are being handled or not.
The 100x oil immersion objective will work without oil just fine, but the image will have reduced contrast and resolution. The oil isn't neccessary and nothing bad will happen if you don't use it. -_-
Lajos Winkler it will defract and will not have a clear image if you don't use the oil. It is necessary
Josh H he meant that not using oil wont break the lens or stuff
Great video thanks
Nice explanation 💪🏻🌟. Where's your lab coat 😱😵
i should have seen this before the desaster that i did in the lab
69 likes, nice
thanks great
thanks
Why not talk about adjusting the iris diaphragm for improved contrast and resolution. To remove air bubbles in the oil, rock the 100X objective back and forth through the oil.
Thank you! I had a hard time doing this in microbio lab today :/ Definitely know what to do differently now
can I use mineral oil or baby oil for the oil immersion obj?
We actually did a research project on that and we used 3 oils as substitute and compared them if which one is the best to use as an alternative for immersion oil. It was virgin coconut oil, baby oil and castor oil and according to what we actually performed, the castor oil gives the best results. It is so clear and almost as the same as the immersion oil.
NO..Use only immersion oil. It has refractive index of 1.515. Same as glass cover slip and slide !
good stuff Brutha!
wiping slide with paper towel will also remove the smear, so bad idea to do .
It has a cover slip on.
