Abstract

See full text

A two-position screw cap culture tube includes a snapping ring on the tube, with a pair of recesses in the snapping ring that provide an aerobic clearance, and a snap groove on the cap. The snap groove engages with the snapping ring when the cap is screwed into a first position that provides a second aerobic clearance between the top of the tube and the cap, to provide an air path and an aerobic culturing system. The snap groove disengages with the snapping ring and the tube is pressed against the underside of the cap to block the air path and provide an anaerobic culturing system.
