How To Use Immersion Oil

I've just bought Optika B-293PLi model microscope which has 100x Oil/Water immersion objective.
I didn't use cover slip while looking water because of that, but when I changed 100x to 40x dry objective, 40x also touched water a couple of times. At first, I didn't pay attention to the situation, but now, I'm worried that I could damage 40x objective lenses irreversibly.
Could 40x objective's lenses be damaged with these few occurrences?

Ow, the word for lens in Polish is obiektyw, didn't know it was similar in English

short and full of the neccessary information, exactly what im lookin for. Thanks!!!!

Thanks man 😋😋

Thank you. This was a great lesson.

Impressive .........😇

when using light microscope do you start the largest or smallest distance between the lens and specimen/why?

Thank you! That was precisely what I needed.

Crazy question: Why not make a sealed 40x? Seems like you could charge a premium for them.

Thank you! This helped

Thank you! This helped

Do I have to use oil on my oil condenser with my none oil objective

Thanks boss. I finally took out my nikon microscope and have started exploring it. This helps as I don’t know the purpose of some parts.

Wow...

Thank you!!!

Thanks for sharing. God bless you

Are their lower power oil sealed objectives available to avoid situations where students or trainees would likely make this kind of handling mistakes ?
Great video.

Thanks

thank you so much. I am currently taking microbiology from home and this video has been great.

THANK YOU!!

nice music man, blew my ears away.

Thankyou 😊

شكرا جزيلا

We teach NOT to lower the stage to add the oil because you should only use the fine focus with the oil immersion and never the coarse focus. Is that not standard practice?

Too darn clear and to the point video 🤭🤭🤭 love it...

Thanks! I've been wanting to look at some of my bdelloid rotifers at very high magnification!

I'm learning how to use a microscope that I got to help with some projects I'm working on. I'm not a professional or student, so I wasn't taught any of this. I'd actually never even heard of using oil like this before I got my scope. I'm SO glad I watched this before using oil! (It's probably in the instruction manual, but who reads those?)

Thanksgiving you so much sir

Thank you. Superb information.

Very well explained thanks.

Short, sweet and to the point. Good clarity.

thanks bro ❤️

why the heck don't they just seal all of the objectives??????????

I want only this stand only I have already microscope

Thank you. You saved me from my newbie ignorance. 🙂

I've just bought the microscope and immersion oil is something I'd never come across before. Thank you for this very clear and concise explanation. I think you may well have saved me money and grief!

Why don't you just make all the objectives able to to be immersed in oil without damage even if they don't need the oil?

Great and informative video! I will share this in class with my students. Thanks so much for this!

Great video and great information

Newbie here. Thanks for doing this video. Would have probably ruined my 40x had I not seen this.

One should never try to clean the lower objectives?

Perfect., Thanks.

Thanks very much. I bought a Japanese (Tokyo) microscope in the Recycle Shop for a wapping 38 euro. It even includes the quality control checklist. And guess what, it has a 100x objective, that my secondary school never had. This video is great. When you know microscope basics, you can carefully do the first oil immersion viewing.

And the warning, never get any oil on the other objectives, for you really need to buy a new one, that is a good tip. I'll make it a habit to remove the object glass that has immoil, immediately. Keep the other objectives away. Hai!

Cheers! Nice one.

Thanks a lot

U earned a sub

Thanks 🙏
