Building Hermetic Membranes in EVE Online

What it takes to make Hermetic Membranes, straight from the game's own blueprint data: every material and how many of each. The calculator above prices that list at one region's orders and draws the whole chain as a graph.

What goes into one run of Hermetic Membranes

3 units per run - this one is made on a planet, not in a station
Material	Per run	Can be built too
Genetically Enhanced Livestock	10	yes - its own chain
Polyaramids	10	yes - its own chain

Production runs in whole batches. One run of Hermetic Membranes gives 3 units, so asking for fewer than that still means one full run - the game has no half runs, and rounding down would quietly tell you to buy the missing pieces.

For what Hermetic Membranes actually is - mass, volume, attributes and the description from the game - see its item page, and for what it trades at right now, its market page.
