Frey Scientific 1385196 Dialysis Flat Tubing, 10' Length, 1" Width

Used this for a biology class and it worked just as I needed it to. Unfortunately, I only needed 60 cm of it, so the rest is probably never going to get used. Maybe I'll give it to my biology lab instructor, haha!

Was what I needed but it came late

Used for starch and iodine lab with students. Worked very well

Same stuff as in the catalogues - less expensive, and quickly shipped to plug in the holes for a last minute lab. Couldn't be more pleased. Did what it should - the Lugol's flowed in, and the glucose/starch stayed inside.

This worked great for my AP Biology class. You'll want to order several rolls as I got approximately 5 meters out of one roll. This will let water/iodine diffuse through but not sucrose as it is too large of a polysaccharide.

I had to purchase this for a biology lab. It served its purpose but not I have a ton left over!

well it Work as it's suppose to

Excellent product. Well packed Many thanks
