Need Ion Exchange Membranes

September 9, 2011

I need to get a hold of some Ion Exchange Membranes. In particular I need membranes capable of exchanging Na+, H+ and OH- ions. I know that Nafion is a good for H+ and Neosepta is good for Na+ but I don't need a whole lot of these membranes. Where can I get some cheap sample-size quantities where I don't have to call each company and talk directly with somebody just for them to say, 'we only work with large industrial customers'?
