This product worked very well for my daughter's advanced biology osmosis lab. Once it is soaked, it became very pliable and worked perfectly so that she could study the difference in molecule sizes in a solution. I would definitely buy this again.
Exactly what we expected!
I had no experience using this product, but it was simple to use for our osmosis experiment.
Great to work with
I think these were actually longer than 5 feet because I cut them into 1 foot strips and I got 7 out of each of the 2 I purchased, which is cool.
These are excellent membranes to use. They opened easily once soaked in water and we were able to do an osmosis experiment easily with it.
I love Home Science/Training Tools! They have the best customer service around!
