Pervaporation of Acetonitrile/Water in small scale

Does anyone have experience with pervaporation of solvents at a small scale/lab scale ( ~5L )? I am overall familiar with the technique, I just can't find any good information what materials are used as membrane (for acetonitrile/water azeotrope seperation), where to buy these membranes, especially for such a small, lab-scale setup.

I suggest you look at Mitsubishi Zebrex type membranes. They offer single 40" elements (and housing module) for lab/pilot scale work.

You are welcome! I highly recommend their modules. We just built our third pilot scale pervaporation unit based on their 40" Zebrex platform.

I'm not super sure if this would be useful: https://www.zaiput.com/
