Some embodiments disclosed herein provide flow path inserts that can redirect flow paths in syringes with axially aligned tips to an outer edge of the syringe. When connected in line with other components, air can become trapped in the system. The syringes can be positioned generally horizontally and air bubbles can be disposed within the body of the syringe. The air bubbles rise to the top or uppermost portion of the syringe. The flow path inserts can facilitate the transfer of the air bubbles disposed within the syringe out the flow path defined by the flow path insert. Some embodiments disclosed herein provide a spinning luer connector for connecting components of a fluidics system.
