DuoClick™ Glass Culture Tubes feature a unique, patent pending screw closure system. DuoClick tubes completely eliminate the excess force, splashing and general frustration of traditional snap-cap culture tubes. The advanced cap design includes two distinct positions for aerobic and anaerobic culturing (see image no. 2). Just rotate the cap to the first click to secure the cap in the aerobic position. Or, rotate it past the second click for a leakproof, airtight seal for anaerobic culturing.
DuoClick tubes are available gamma sterilized, with screw caps attached, and in our exclusive ready-to- use rack packaging. Polypropylene tubes can be centrifuged at up to 4,000xg (1,400xg for polystyrene tubes).
