Yo this literally saved me! My Bio teacher moves too fast when explaining things and I've been getting all of my measurements wrong as a result so this was SO helpful now I feel confident I can do well on our next lab.
I've had 4 different people tried to explain it to me during Environmental Biology Lab at Uni, and I just couldn't understand and wrapped my brain around it. But you've explained it soooo well!! Thanks heaps!
Thank you so much! This is amazing. My teacher likes to talk in circles and it is so difficult. Thanks for being direct and making things much simpler!
7.5 um is almost a little large for RBCs. The Normal clinical hematology value for RBCs is 6.7um to 7.8um. Rather the proper technique to measure the size of RBCs is to use a hemocytometer.
How could we approach to calculate cell volume (average) through a microscope? Kindly provide me any research articles published for the above video and for cell volume too?
you are right, this is just an estimate and you do the best you can. If this were on a test, the answer sheet would suggest a range of possible answers, not an exact. There are other tools used like a graticule eyepiece for a microscope that can be more precise.
Sorry for late reply... the Field of View is (ocular / objective)... most ocular (eye) lenses are 10x then divide by the objective (lens you manually select). IE. 10x / 40x = a field of view of 1/4 or .25mm... convert to micrometers = 250um

Same 😂😂
Lol same
SAME! But he didn’t even explain how to do it.. or he did, duchemin never explains properly

really appreciate hearing that this helped you. thanks
This video really saved me. My teacher has too much fun making things super difficult for us and not elaborating. You are the best!!

happy to know that this helped you.
I have a great teacher but you explained this so easy. Thanks. Sometimes it is in the delivery.
Appreciate the quick tutorial, homie!
Literally saved my life :D

What I was looking for to cut down my time in assessing specimen size! Thanks Professor Pete!
Can you please explain how you calculated FOV in detail first each objective lens which you have in cheat sheet like 40x=0.45mm ?Thanks in advance
you just made this soooooo easy. THANKS!!!
thanks, this was very helpful! i have a test tomorrow that i would have failed had i not found this video
literally just saved me in a university exam
Thank you so much I finally understand it!!!
can u do image size/magnification and then multiply by 1000?
Hi there, Mister you broke that concept down to the A- B- C which was nice so, thank you and blessings.
Thank you so much for your help.
Where did .45 come from? What conversion is that?
Thanks helped with my science lab
thanks man really helpful vid
Thanks, It was a great help
This helped me bro, I had covid and missed out on the time we covered this
This was extremely helpful , thank you
Glad it was helpful!
thank you this will save my test
You help me befor 3 hours from my exam thank you my brother❤
This helped so much! Do you know where I could get practice problems?
two years and no replies rly sadge

awesome man!
You just saved my grade
hi, thank you for excellent video. can you help me with how to find actual image size if I have an eye piece graticule please? thank you again :)
how about 100x ?
I assume FOV at 100x is .18mm and 180um?
thank you!
I know this is the rule, but I just feel it's a guess... What about the space where there's not cells to count? I kind of don't get it yet :/

thats very helpful thanks!
is it possible to determine a plants sex looking at the cells threw a microscope
How did you get each millimeter for each magnification? Thanks!
They might be on the objective lenses.
Thank you!!!
Science saver
how about the WIDTH tho
super! thanks
Thx bro
what is 500x then?
I think 100x is .18mm or 180um so x5?
I thought cell size=pointer length / cell #
How about 100X?
I think it is .18mm or 180um
What do you think of poop sir?
omg ty, my professor does not explain anything in lab
Ty
yaaaaaaaas!!!!!!!!!!!!!!!!
my bio teacher just eats in class and puts on amoeba sisters. weirdo.
been trying for weeks to change bio classes.
Hi, the method is right but then of course, there is the question how to calculate the size of the field of view.
I assume you have to measure that, there is no calculation method, is there?

I could kiss you. Thanks!
