Visking tubing is made of cellulose and often used as a model gut in class room experiments.
The name of the company visking corporation
sausage tubes or casings is what you did at the job. The company was in bedford park, il or Chicago, il in the 1950's
It has Smll spaces which only allow small particles like glucose, galactose and furctose, as well as amino acids, fatty acids and water to pass through
Visking tubing is a kind of seamless semi permeable tubing, a cellulose tubing, that is made of regenerated cellophane. It is used as an edible casing for sausages or as a membrane in dialysis.
Put a sucrose solution into the visking tube and fasten the ends, then place it in water (at different temperatures). The varying temperatures would quicken or slow the rate of diffusion (osmosis). Then using iodine, you put some in the water that the visking tube was in and if it turns dark blue/black the more sucrose has diffused. This can be put into a calorimeter to check the intensity for different temps. You should find that the higher the temp. the higher the rate of diffusion (because particles are excited and have more kinetic energy and move more). Hope this helps =) Sana (17 yrs)
You may be thinking of the blood capillaries. Like visking tubing, their walls are able to let substances diffuse in and out. This is also true of the cell membranes. However both of these are much more permeable than visking tubing. The kidney contains semi-permeable membranes which allow urea to pass through but not other substances such as proteins.
it needs to dry
Carbon Dioxide (CO2)
fine glucose molecules can pass through the wall of the visking tube.

Cannot pass through visking tubing: sugar starch lactose sucrose Can pass through visking tubing: Iodine Glucose Maltose
small intestine

it is different because widts of the tube and intestine may vary
the visking tubing is useless and we need an alternative. can u helpful human beings help please? we are in the middle of a chaotic crisis trying to find the reason for osmosis. please help you kind human beings :) i hate you bye -from the scientists of Mars :
small intestines and the blood that surrounds in (ie in the capillaries)
can someone tell me what is good about visking tube and whats bad about it asap because i need to give my homework by tmor and my homework relates 2 that

yes it can
