I am trying to locate a group that fabricates the DOW gas transmission cell
or a similar cell device used in Moisture and Vapor transmission rates of
thin film polymer materials. ASTM 1434 listed Custom Scientific Instrument,
Inc, Whippany, NJ. as a fabricator of the instrument. I cannot locate them.
I desire to determine gas transmission rates of pheromones across thin film
polymers. Can anyone help me?
