Early Reverse-Osmosis Attempts

We made some progress developing seals for the reverse-osmosis films. Using a water-sample bottle and some plumbing putty, we were able to seal the film to prevent leakage from the fittings. The rate of permeate through the film seemed good (see video), however, we did not achieve the desalination we expected, so we're doing additional research. We're concerned that we might have damaged the film while sealing it or perhaps it requires some treatment before use.
