Abstract
An bubble-resistant injector port for fluidic and microfluidic devices includes an air-exhaustion feature to reduce the inclusion of bubbles or voids in injected samples, particularly in samples injected by a micropipette. The air-exhaustion feature comprises an air-exhaustion cavity in gas communication with the injector port through a narrowed channel that permits a flow of air into the cavity, while impeding a flow of injected liquid into the cavity.
