OMIS remix

Here’s the first published remix of my Open Millifluidic Inquiry System (OMIS) made by Thingiverse member Steve Gordon.  There are a couple of nice tweaks, including the use of epoxy to keep the support rods in place (a semi-permanent solution, since many epoxies can dissolve in acetone, and since PLA was used in this build, OMIS won’t be permanently damaged by an acetone treatment).  Another nice tweak is the use of automatic pipette tips instead of syringe needles to connect the syringes to the millifluidic device.  I’ve got some projects that will involve acid in one of the channels, so I need to explore this hack further.

More information about OMIS, such as the bill of materials, build guide, and some ideas on how to use it can be found on my OMIS page.
