This is a visual way of demonstrating a semi-permeable membrane.
This video has been developed in partnership with the Society of Biology.

"what you want to do with your students" *the student watching this* the student has become the teacher :D

[@lukrecja_blaq]

I appreciate the clear explanation and presentation. You have an amazing smooth voice!

[@talktoghazaleh6419]

this was absolutely amazing, I really wish you make more videos.

[@dettolsanitizer7839]

Very good explanation, now i understand better

[@abdellatifeltarshouby1589]

Thank you guys.

This is great!

a good demonstration !

What about the pore measuring of Visking tubing?

[@michelleadel]

Brilliant! So very useful to see these practicals done - hope to see many more!

[@arokiyaraj133]

What is the MWCO of the semipermeable membrane?

[@fathimafarween3310]

very good explanation

Damn, learnt a lot from you Laura, sad to see you go, RIP 1983-2021.

how did she die

[@morningstar6223]

Can we able to use these visking tube for separation of proteins from polysaccharides?

[@dr.parasdayma2759]

Can anyone answer me that whether we can use it for partial purification of enzyme?

Thank you, my science lesson will go by so much smoother now :)

[@gachaTeddyBear1127]

I have question two questions
1) why it was important to wash the outside of the tubing?
2) which nutrients-starch or sugar-were able to get out of the tubing?

[@ggbro_22x79]

Starch cannot get through the Viking tubing but glucose can move through

[@mariamalik3480]

Thank you for the video! Now I know how the test works. My class didn't get the chance to do the experiment because we were missing out on too much chapters in our lesson due to our practical teacher who's not really good at teaching probably because she's new.
But now we have a new teacher because the practical teacher transfered school and she was pregnant at that time. Our new teacher decided to not to do the experiment or we won't cover all the chapters we're missing out for the final exam. But anyway, thanks for the video! Really liked your explanation because it's easy to understand ^^

[@adiyatneil9947]

hold on, how is it that starch is found inside the visking tube? isnt starch a larger molecule compared to glucose? shouldnt the partially permeable membrane of the visking tube only let smaller glucose molecules pass inside?

[@steedenscfc]

Guessing you didn't watch the video, give it another go, listen, and you'll see.

[@YT_-vz9ru]

Why is Glucose found in the water surrounding the Visking tube?

[@ammaralharbi3727]

Bella y because it is

[@lisereneedelport2381]

Because glucose molecules are small enough to pass through the visking tubing

[@adiWatches]

Lise Renée Delport u are correct

[@fire_shield9284]

anyone else here cause there science teacher made them wacth this video

Hello fellow students

[@remote6976]

Why did you wash the tubing ?

[@nareshsivakumar]

I think she washed the tubing so that it "gets flexible to work with".

[@drope9991]

This demonstration is based on a false concept: that glucose and starch are soluble in water, which is false. Ony glucose is soluble so it generates a water potential from the inside and the outside, generating the glucose to go through the membrane due to a diffusion. Starch on the contrary is not soluble in water, thus not generating any concentration potential from the inside and the outside and so the molecules have no pressure forcing them inside the tube
