Close-up of the titanium-frame RAS prior to deployment. The main 50-port valve is in the center, with teflon tubes going to each sample container beneath the blue filter holders. Fluid is pumped through the stainless-steel clad teflon tube from the vent and into the valve and then directed to one of the 48 sample holders. Between samples, a small amount of acid is backflushed into the line to prevent clogging in the valve.
