Microfabrication Equipment

Microfabrication is conducted in the Microfluidic Foundry, Mechanical and Industrial Engineering, room 405. To get access to this lab see our Access and Fees page. The Microfluidic Foundry is a clean environment, all users must gown from head to tow before entering the clean room and no paper or fibrous materials are allowed inside the clean room. Materials left unattended in the clean room will be immediately removed in an effort to keep work space uncluttered. Consumables provided by the facility are: nitrile gloves, ethanol, methanol, isopropanol, acetone, nitrogen cylinders, SU8 developer, low-lint wipes, parafilm, scalpels and razor blades, aluminum foil, scotch tape, microscope slides, and Scotch tape.  Other consumables such as PDMS elastomer kits and SU8 photoresist need to be supplied by the user.
