Protium is all of the components you need to create a D5 or DDC pump and reservoir combination. We set out to create the most minimilistic and compact pump and reservoir combination, but at the same time with the most options and compatibility. Each component is carved from a solid piece of material on a CNC Mill or Lathe. Creating our different finishes, frosted and polished acrylic is difficult which is why you don’t often see it. Protium is designed for people who want the freedom to create anything without restriction.
