Thank you! I followed the same steps, great to confirm that. Is there any consideration for long term storage?

Great! I am using it for PLGA Preparation. Thanks for you great help!

I am preparing 10% PVA" 99+% hydrolyzed  solution for membrane synthesis 

Any consideration for long term storage ?

Hello Asmaa,

I don't believe there's any consideration for preserving it. You can store it in a room temperature. I read somewhere people add preservative, like benzisothiazolinone with/without methylisothiazolinone.

I hope that help.

thanks a lot 

Dear Josh,

I would like to prepare partially, moderately and completely hydrolyzed polyvinyl alcohol grades, how can I achieve these? pls.
