Very comprehensive. For some reason I find that companies are very secretive about the chemical composition of their synthetic oils. I believe that many modern oils are based on certain epoxies. I have also read a paper about the use of methyl salicylate as an alternative but never tried it. One thing to mention about leaving oil on the objective is that if you use other objectives then the oil immersion one will eventually find its way to being at a steep angle in the turret so the oil can drip into the spring mechanism if left uncleaned and over time cause the retraction feature to cease up which can make focussing a problem and also cause issues with potentially damaging the specimen if you try to rack the focus too far down while trying to get in focus. For those interested in more technical aspects of oil immersion and numerical aperture of illumination I have published a recent paper in the journal of microscopy related to that subject. Thanks for another good video.
Even if I won't use oil immerion, it's still great video. As always ❤
came to learn about immersion oils,
stayed to hear you say "oil",
thanks :)
Sir thanks to you. I am not from Europe or America. I am from Bangladesh. I am happy to see a man is teaching ameture microscophy that is nessesary for me. I wish may Allah grant you the right path of life. Zazakallh kahiran.
I'm always forgetting to put cover slips on my rock slides before in use oil. 😅
Sir what will happen if we use high power telescope eyepiece(like 4mm or 10mm) in a microscope??
Hello do you have affiliate shop/link Amazon for France? I would like to buy a microscope .
Did future of microscope diagnose for malaria is marketable? Cos many development of small device to dectect malaria parasite rather than using microscope machine😢
sir can you suggest what to observe under compound microscopes?
Hello Microbehunter
Whenever I use oil immersion objective, I see cells floating. What could be my mistake, can you tell?
what adapter would you recommend for a DSLR camera - such as you have in your latest videos.
Depends on what quality you expect. But this here is a starting point: ua-cam.com/video/Ju8rgeJr3bI/v-deo.html
you should observe the super dried up solid oil with the microscope and some non dried oil haha wonder if youd see the liquid stuff start to dissolve the solid XD
