In this paper we present a miniature bubble trap for efficient removal of bubbles from microfluidic reactors. The new bubble trap has a 10 mm single chamber with posts of different diameters and has a chamber volume of 20 ┬ÁL. The vacuum chamber situated above the bubble trap allows facile removal of traps. The system is versatile, built using soft lithography and can be readily used in microfluidic systems.
